Caring for Fall Mums in the Garden

Welcome to Episode 16 of the Sunshine Gardening Podcast! Thanks for joining me for this episode and I am your host Kristin Hildabrand, Warren County’s Extension Agent for Horticulture. I don’t know if you have been out and about lately but have you all noticed the bright and beautiful mum displays right now!? Mum is definitely the main flower that is in season and to be honest, it is the ray of sunshine in my life! I’ve been amazed at all the colors of mums being offered. One grower that I follow on Facebook, she offered a variety called ‘Darling Pink’ and another one called ‘Strawberry Ice’ mum. Both were absolutely gorgeous!

So, it is officially after Labor Day and home gardeners are planting gorgeous fall mums in their garden and landscape. Have you ever wondered what it takes to help these blooms last? Well, wonder no more because today, I am sharing 5 tips for caring for fall mums in the garden. These tips will help the mums last longer during the season and help them overwinter and come back for next year!


Tip #1: Select mums with more buds than flowers.

When selecting a mum to take home, choose a plant that has several tight buds on it. Over time, the buds will slowly open and help make the flowers last longer. Those buds that haven’t opened will last longer on your deck, patio, porch, or yard.

If you are looking for an instant pop of color to help dress up an outdoor event, go ahead and purchase mums with several flowers in bloom.


Tip #2: Choose the best location.

When choosing an ideal location for growing mums, select a site that receives at least 6 to 8 hours of direct sunlight. Avoid garden spots that receive less than the recommended amount of sunlight hours, since it will dull the vivid blooms.

The next thing to remember about proper site selection for garden mums is to situate them in moist, well-drained soil. Mums are prone to getting root rot issues, so a well-drained soil helps in draining water around the root system. If your soil is less than ideal, incorporate 2 to 3 inches of organic matter such as compost or well-rotted manure. By adding organic material, you are helping the soil drain better and improving nutrient holding capacity.


Tip #3: Plant mums in the ground early.

If your goal is to overwinter mums to get them to come back next year, it is crucial to get the ground prepared and plant as soon as possible. The other important part to this tip is that you need to make sure that the mums don’t have any blooms at time of planting. By planting mums with more buds and planting them early, this allows the root system plenty of time to get established in the soil.

Make sure to plant mums at the same depth that they were growing in their original container. I recommend digging the planting hole first and then adding the mum still in the container to the planting hole. This specific planting procedure allows you to be a better judge of how much more depth or width is needed. Once the planting hole passes inspection, take the mum out of the container and plant into the hole. Avoid adding any fertilizer at this time. If planting more than one mum, space plants 18 to 24 inches apart.


Tip #4: Apply water and mulch.

After planting, water in the mums by targeting the stream of water right at the base of the plant. Avoid splashing the foliage which can lead to foliar diseases. It is best to practice morning watering routines rather than late afternoon watering. The morning watering routine allows plenty of time for the plant to dry off before night-time arrives.

Apply 2 to 3 inches of organic mulch such as woodchips, shredded bark, chopped leaves, or compost to help conserve soil moisture. This step is also important for overwintering since it will help protect the plant’s root system from extreme cold temperatures in the winter.


Tip #5: Pinch when needed.

Lastly, most garden mums will benefit from pinching the plants 2 to 3 times in spring and early summer. Pinching produces a more compact bushier appearance with additional flowers. Pinch back plants when new shoots are 6 inches tall by using pruning shearers or hedge clippers. After pinching, new lateral shoots will begin to develop along the stems. Repeat this same process again when the new shoots reach 6 inches and continue pinching until early July.

NEW Farm Tax Exemption Changes

Agriculture Exemption Number Now Required for Tax Exemption on Farm Purchases

Author(s): Jerry Pierce
Published: July 19th, 2021

A new Kentucky law requires that farmers apply for an Agriculture Exemption Number to make
qualified purchases for the farm exempt from sales tax.

The application Form 51A800 is currently available on the Department of Revenue website
here: https://revenue.ky.gov/Forms/51A800%20(4-21)_fill-in.pdf


The application requires verification of agricultural activity. Any one of the following documents may be submitted with the application:
• IRS Schedule F, Profit or Loss from Farming
• IRS Form 4835, Farm Rental Income and Expenses
• Farm Service Agency number
• Other type of verification
Once approved, the Department of Revenue (DOR) will issue an Agriculture Exemption Number by letter. The number must be renewed every three years. The Agriculture Exemption Number does not exempt purchases from sales tax. It must be used with Form 51A158 Farm Exemption Certificate for farm purchases and machinery, and with Form 51A159 Certificate of Exemption for Materials, Machinery and Equipment for construction of farm facilities. These certificates must be presented to each vendor or supplier along with the DOR letter. Farmers may still use Forms 51A158 and 51A159 without an Agriculture Exemption Number through
June 30, 2022, by using their driver’s license number. Exemption Certificates without an Exemption Number will expire and no longer be valid as of July 1, 2022. Forms 51A158 and 51A159 both list specific items that qualify for exemption from sales tax on
purchases of farm-related items.

For more detail on exempt purchases see Kentucky Revised Statutes (KRS) 139.480. KRS 139.481 was passed in the 2020 legislative session and became effective on January 1, 2021. It is intended to improve the way farmers register tax exemption on sales of qualified purchases with vendors and suppliers. Businesses will also have access to a database for use in purchases with vendors and suppliers. Businesses will also have access to a database for use in confirming the agriculture exemption number.

Watch out for Horse Flies

by: Lee Townsend, Extension Entomologist 
University of Kentucky College of Agriculture 

Horse flies and deer flies are bloodsucking insects that can be serious pests of cattle, horses, and humans. Horse flies range in size from 3/4 to 1-1/4 inches long and usually have clear or solidly colored wings and brightly colored eyes. Deer flies, which commonly bite humans, are smaller with dark bands across the wings and colored eyes similar to those of horse flies. Attack by a few of these persistent flies can make outdoor work and recreation miserable. The numbers of flies and the intensity of their attack vary from year to year. 

Numerous painful bites from large populations of these flies can reduce milk production from dairy and beef cattle and interfere with grazing of cattle and horses because animals under attack will bunch together. Animals may even injure themselves as they run to escape these flies. Blood loss can be significant. In a USDA Bulletin 1218, Webb and Wells estimated that horse flies would consume 1 cc of blood for their meal, and they calculated that 20 to 30 flies feeding for 6 hours would take 20 teaspoons. This would amount to one quart of blood in 10 days. 

Female horse flies and deer flies are active during the day. These flies apparently are attracted to such things as movement, shiny surfaces, carbon dioxide, and warmth. Once on a host, they use their knife-like mouthparts to slice the skin and feed on the blood pool that is created. Bites can be very painful and there may be an allergic reaction to the salivary secretions released by the insects as they feed. The irritation and swelling from bites usually disappears in a day or so. However, secondary infections may occur when bites are scratched. General first aid-type skin creams may help to relieve the pain from bites. In rare instances, there may be allergic reactions involving hives and wheezing. Male flies feed on nectar and are of no consequence as animal pests. 

Horse flies and deer flies are intermittent feeders. Their painful bites generally elicit a response from the victim so the fly is forced to move to another host. Consequently, they may be mechanical vectors of some animal and human diseases. 

LIFE CYCLE

The larvae of horse fly and deer fly species develop in the mud along pond edges or stream banks, wetlands, or seepage areas. Some are aquatic and a few develop in relatively dry soil. Females lay batches of 25 to 1,000 eggs on vegetation that stand over water or wet sites. The larvae that hatch from these eggs fall to the ground and feed upon decaying organic matter or small organisms in the soil or water. The larvae, stage usually lasts from one to three years, depending on the species. Mature larvae crawl to drier areas to pupate and ultimately emerge as adults. 

PROTECTING YOURSELF

Deer flies are usually active for specific periods of time during the summer. When outside, repellents such as Deet and Off (N-diethyl-meta-toluamide) can provide several hours of protection. Follow label instructions because some people can develop allergies with repeated use, look for age restrictions. 

Permethrin-based repellents are for application to clothing only but typically provide a longer period of protection. Repellents can prevent flies from landing or cause them to leave before feeding but the factors that attract them (movement, carbon dioxide, etc.) are still present. These flies will continue to swarm around even after a treatment is applied. 

Light colored clothing and protective mesh outdoor wear may be of some value in reducing annoyance from biting flies. In extreme cases, hats with mesh face and neck veils and neckerchiefs may add some protection. 

PROTECTING ANIMALS

Horse flies and deer flies can be serious nuisances around swimming pools. They may be attracted by the shiny surface of the water or by movement of the swimmers. There are no effective recommendations to reduce this problem. 

Permethrin-based sprays are labeled for application to livestock and horses. These insecticides are very irritating to the flies and cause them to leave almost immediately after landing. Often, the flies are not in contact with the insecticide long enough to be killed so they continue to be an annoyance. These flies will swarm persistently around animals and feed where the spray coverage was not complete (underbelly or legs) or where it has worn off. Repeated applications may be needed. Check the label about minimum retreatment intervals. Pyrethrin sprays also are effective but do not last as long as permethrin. 

Horse flies and deer flies like sunny areas and usually will not enter barns or deep shade. If animals have access to protection during the day, they can escape the constant attack of these annoying pests. They can graze at night when the flies are not active. 

CONTROL

It is difficult to impossible to locate and/or eliminate breeding site of horse flies and deer flies. They breed in environmentally sensitive wetlands so effects of drainage or insecticide application on non-target organisms or water supplies is a concern. Also, these insects are strong fliers that can move in from some distance away. Breeding sites may be very extensive or some distance away from where problems are occurring. 

Fortunately, horse flies and deer flies are sporadic problems for specific times of the year. Some adaptation in behavior or use of repellents can allow enjoyment of the outdoors.

Be on the Lookout for Late Season Stinging Insects!

As we head towards Labor Day and the unofficial end of summer, people are noticing some our different species of stinging insects. The inquiries we have received have all focused on these insects being Asian giant hornets (aka the “murder hornet”), an insect not known to occur in the state. Thus far, that species has only been found in the Pacific Northwest.

What we do have in Kentucky are things like yellowjackets, paper wasps, and European hornets. Some of these are aggressive in their own right, and others do resemble the Asian giant hornet. Here are some tips on identification and advice on managing these insects, if necessary.





Yellowjackets

Yellowjackets are some of the most encountered stinging pests. These bright yellow and black-colored wasps are usually around a half inch long. The workers of a colony are the ones we encounter most often. In the earlier part of summer there are fewer workers, and they are on the hunt for meat, which they can obtain as prey items such as caterpillars or as scavenged material from garbage and roadkill.

Yellowjackets build papery, football shaped nests in the soil or in shrubs and occasionally trees. These nests expand over the course of the summer and by the end of the growing season can commonly contain thousands of workers. The workers switch from looking for protein to looking for more sugary materials. This means fruit, pop, fruit juices, and frozen treats. These workers and the original queen will all die when winter sets in though. Only new queens produced by the original will go into the next season to produce the next round of nests. The switch in diet and need to protect the new queens can mean more encounters with humans and an increased defensive nature when nests are discovered.





Paper Wasps

There are several paper wasp species that can be encountered. They tend to be 1/2 to 3/4 inch long and have smoky-colored wings that you can’t quite see through. Some species are brownish, others red, with some being black and yellow. One of the more common species, the European paper wasp, has coloration that looks very similar to a yellowjacket except their antennae are orange at the tips.

Paper wasps get their name for building umbrella-shaped nests that are constructed out of paper they make by chewing wood scrapings into a pulp. These nests are often found on trees, shrubs, eaves of homes, rafters, railings, and other semi-protected areas. Paper wasp nests don’t get as large as other stinging pests and as a group they tend to be less defensive of the nest than things like yellowjackets. They will sting though, and it can be quite painful. The nest is annual and the insects will die out by fall, with new queens produced overwintering to found their own nest the next season.





European Hornets

This species is the one that has been most confused for the Asian giant hornet. They are also a non-native species, but are slightly less famous than their larger cousins from Asia. Workers of this species are around an inch long, with queens reaching 1 1/2 inches in length. They have a pattern on their abdomen that resembles a yellowjacket’s and is also black and yellow. Their thorax and head are a mix of yellow with patches of dark red, which helps to differentiate them from the Asian giant hornet as well.

They build large paper nests that they will defend by stinging. These large insects are predators; they will consume almost anything they can catch and will eat honey bees (though not quite as aggressively as the Asian giant hornet). They are also known to steal prey from spider webs to eat for themselves. One other interesting feeding habit they demonstrate, in the fall, the workers will girdle tree branches and small trunks and then drink up the sugary material that leaks out.

Management of Stinging Insects

If folks are dealing with a nest of stinging insects, they should consider contacting a professional to help them eliminate the problem. Of course, that might not be feasible for some, so it is important to note the ways that these pests can controlled by homeowners on their own.

First and foremost, they will need to discover the entrance to the nest. Treating individual workers will not eliminate the problem.

Once the nest or entrance has been discovered, an aerosol wasp and hornet product (examples include Raid and Spectracide Wasp and Hornet) can be applied into and onto the nest. These are quick acting products, often needing just seconds to eliminate the nest. The application should be done at dusk or after dark to maximize control and minimize the chances of being stung. The person making the application should also have an escape route planned in advance and a place of safety to retreat to, just in case.

Extension Master Gardeners Make a Difference with a Certified Monarch Waystation

In 2017, the Monarch Joint Venture organization reported that the iconic monarch butterfly has steadily declined by approximately 90% over the last 20 years. Warren County Extension Master Gardeners wanted to make a difference so they designed and installed a certified Monarch Waystation to provide habitat and to help increase the population of monarch butterflies.  A monarch waystation is a garden that includes milkweed plants which serve as the host plant for the monarch butterfly and a variety of nectar plants that the adult butterfly can use as a nectar source. This garden was situated on the Warren County Extension Office grounds to serve as an educational demonstration plot  so the general public would be encouraged to plant more native and pollinator friendly plants in their home garden and landscape.

A Monarch Waystation committee was formed to assist with the installation and timeline for the project. Committee      members worked closely with the agent throughout the 2020 – 2021 year to plan the certified Monarch Waystation. The committee secured a $1500.00 grant from the Warren County Soil Conservation District as well as other community donations. Other committee members contributed by checking and securing material costs and marketing for the project.

Extension Master Gardeners Interns from the virtual 2020  Master Gardener class were given the task of submitting      garden proposals for the future design of the Monarch Waystation. Completed proposals were reviewed by the     committee at the end of January 2021 and the final design was selected. The final design consisted of a combination of multiple designs submitted from the Master Gardener Interns with several native plants arranged in seven 4×8 feet raised beds. 

Warren County Extension Master Gardeners and Interns worked diligently together throughout the spring 2021 season to construct the Monarch Waystation gardens. Volunteers worked on different parts of the project to build the raised bed garden frames, add soil media components to the beds, plant hundreds of pollinator friendly plants, install the water feature and small bubblers for water sources, mulch plants, and water throughout the week. Visit the Warren County Extension Office website at www.warrencountyextension.com/monarch-waystation to see the entire process from start to finish. 

To highlight their efforts, Warren County Extension Master Gardeners received recognition through local media outlets. Their story was featured on WBKO-TV Channel 13, Spectrum News, and in the Bowling Green Daily Times newspaper.    Another TV segment appeared on the Extension Farm and Home Show during National Pollinator Week.

Warren County Extension Master Gardeners have also registered and certified their waystation through Monarch Watch which is the non-profit organization that manages the waystation. By registering their waystation, Warren County Extension Master Gardeners are supporting monarch conservation efforts and the preservation of the monarch      butterfly.

Master Gardeners have donated a total of 218 volunteer hours to the certified Monarch Waystation. According to the National Independent Sector, the value of volunteer time for the state of Kentucky is $23.10 per hour for 2020. If you multiply the hours donated by the hourly rate, Warren County Extension Master Gardeners have given a total of $5,035.80 to the Warren County community.  Plans are currently being made to install other features for the Monarch Waystation in the fall 2021 season.

Garden Spiders in Kentucky

If you have walked through the garden lately, you may have noticed several spiders. Now for some people, the thought of a spider makes them want to jump out of their shoes! But interestingly enough, spiders play an important role in a healthy ecosystem and there are benefits to having them in the garden. To help explain more about spiders, I called up Dr. Ric Bessin, University of Kentucky Extension Entomologist to discuss more about the specific types of spiders found in Kentucky. I was amazed to learn about all the different types of spiders and the benefits that they can offer in our environment! So, make sure to stay right here on the Sunshine Gardening Podcast to hear the full interview!  

Introduction

  • Spiders are known as “arachnids,” and they all have 8 legs, 2 body parts (cephalothorax and abdomen), and no antennae.  
  • Arachnids also have fang-like mouthparts called “chelicerae” which insects do not have.  Insects and arachnids both belong to the same Phylum (Arthropoda), but insects are not arachnids, and arachnids are not insects.
  • Spiders can be distinguished from other arachnids in Kentucky by the connection between the abdomen and the cephalothorax.  In spiders, the connection between the cephalothorax and the abdomen is a narrow stalk.  In other Kentucky arachnids, the connection between the two body regions is broad, so that the distinction between the cephalothorax and abdomen is not obvious.

(Newton & Townsend, 2010)

There are many different types of spiders found in Kentucky. Here are a few types mentioned in this podcast episode.

Types of Spiders

Wolf spiders

Size: Wolf spiders range in size from tiny (the size of a pencil eraser) to about the size of a U.S. silver dollar, with legs outstretched 
Color: There are many species of wolf spiders in Kentucky, but most are dark or light brown, usually with contrasting spots or stripes. 
Features: Wolf spiders are fast-moving and they are typically seen running on the ground. They are not web builders. 
Notes: Wolf spiders often wander into homes. Because they are brown in color, wolf spiders are often mistaken for brown recluses. Like most Kentucky spiders, the bites of wolf spiders are harmless except to allergic individuals. Wolf spiders are among the most common kinds of spiders in Kentucky.

(Newton & Townsend, 2010)

Funnel web/grass web spiders

Size: About the size of a U.S. quarter, with legs outstretched.
Color: Brown with prominent longitudinal gray or tan stripes. 
Features: Prominent hind spinnerets: these are two, small, finger-like projections on the end of the grass spider’s abdomen (used to spin the web). Many other spiders have spinnerets, but they are very large and distinctive in grass spiders. 
Notes: Grass spiders are very common in Kentucky lawns where they build large, funnel-shaped webs. They also occasionally wander into homes. Because they are brown and of a similar size, grass spiders are often mistaken for brown recluses. Like most Kentucky spiders, though, the bites of grass spiders are harmless except to allergic individuals.

(Newton, Townsend, 2010)

Fishing spiders

Size: A little larger than a U.S. silver dollar, with legs outstretched.
Color: Brown with contrasting, darker brown patterns. 
Features: Very large brown spiders; sometimes seen running on the ground or sitting motionless on tree trunks. 
Notes: Fishing spiders are common near streams and wooded areas in Kentucky, and they sometimes wander into nearby homes. They are among the largest spiders in our state, but they are not considered dangerous. Like most Kentucky spiders, the bites of fishing spiders are harmless except to allergic individuals. They are sometimes mistaken for brown recluse spiders, but adult brown recluses are smaller and lack the fishing spider’s distinct dark brown patterning.

(Newton & Townsend, 2010)

Jumping spiders

Size: Typical jumping spiders are about the size of a U.S. dime, with legs outstretched. 
Color: There are many species of jumping spiders in Kentucky. Many are gray or black, while some are vividly colored. 
Features: Jumping spiders have distinctive, large eyes and a “flat faced” look. They are characterized by quick, herky-jerky motions and they do not build webs. 
Notes: Jumping spiders are common on the outsides of homes and buildings and they often wander into homes. Because some are brown in color, jumping spiders are sometimes mistaken for brown recluses. Like most Kentucky spiders, though, the bites of jumping spiders are harmless except to allergic individuals.

(Newton, Townsend, 2010)

Crab spiders

Size: Typical crab spiders are about the size of a U.S. nickel, with legs outstretched. 
Color: There are many species of crab spiders in Kentucky. Some are brown or tan, but most common species are bright white or vivid “neon” green or yellow. 
Features: Crab spiders are low and flat and their front two pairs of legs are very long. Crab spiders are not web builders. 
Notes: Crab spiders are very common in Kentucky flowers (where they hunt for bees), but they sometimes wander into homes. Because some crab spiders are brown in color, they are occasionally mistaken for brown recluses. Like most Kentucky spiders, the bites of crab spiders are harmless except to allergic individuals.

(Newton & Townsend, 2010)

Orb web spiders

Size: Orb weavers range in size from tiny (the size of a pencil eraser) to a little larger than a U.S. silver dollar, with legs outstretched. 
Color: There are many species of orb-weaver spiders in Kentucky. Some are solid tan or brown, while others are colorful with vivid patterns. 
Features: Orb weavers are distinguished by their webs: no other common Kentucky spiders make organized, circular, grid-like webs. Orb weavers are almost always encountered inside their webs. 
Notes: Orb weavers are commonly found on porches and gardens in Kentucky, especially in late summer. Occasionally, they will wander into a home and build a web in a doorway or windowsill. Some orb weavers are very large, but, like most Kentucky spiders, the bites of orb weavers are harmless except to allergic individuals. The Yellow-and-black Argiope (pictured below, top left), one of the largest spiders in Kentucky, is a type of orb weaver.

(Newton & Townsend, 2010)

Harmful Spiders

There are two Kentucky spiders that can cause harm to humans: the black widow spider and the brown recluse spider. Tan to dark brown, a brown recluse’s abdomen and legs are uniformly colored with no stripes, bands, or mottling. The legs are long and thin and lack conspicuous spines. They have a dark violin-shaped mark on their back, with the neck of the violin pointing toward the rear of the spider. This feature is consistent in adult brown recluses, but is less obvious in younger spiders.

Their bites are serious and require immediate medical attention, but brown recluses are timid and unlikely to bite unless handled. These spiders are common in all areas of Kentucky. They tend to occur in hidden locations indoors and outdoors, such as piles of cardboard or paper, stacks of cut wood and wall-voids of buildings.

Black widow spiders are also common throughout the state. The female black widow is about a half-inch long and is glossy black with a variable number of red markings on the top and/or bottom of her abdomen. Adult males smaller and are similar in color, but with a few added white markings. Juveniles are highly variable. Their bites are very serious and require immediate medical attention, but the spider is timid and unlikely to bite unless handled. They tend to hide out in concealed outdoor locations such as piles of rocks or firewood and dark corners of garages and out-buildings. Females are common; males are very rarely encountered.

If interested in learning more information about spiders found in Kentucky, check out the Critter files that are posted on the University of Kentucky Extension website. Find the link to these files posted below in the references section. Field guides can also be a useful tool to keep on hand.

Using Wheat for Grazing

Source: Jimmy Henning, Chris Teutsch, Ray Smith, UK Extension Forage Specialists and Tim Phillips, UK Plant Breeding and Genetics

It may surprise you that producers use as much as 25% of Kentucky’s wheat crop for forage or cover crops rather than harvesting it for grain. Wheat is a very attractive option to forage and livestock producers because it is winter hardy, planted later in the fall and adapted to most soils in Kentucky.

Livestock can graze wheat as forage in the fall and spring. The crop performs best as a forage on ground that is limed to a pH of at least 6.4 or higher and fertilized according to soil test recommendations. If you plan to graze the wheat, splitting the nitrogen application between fall and spring will increase total forage production. Make the fall application before seeding and a late winter/early spring application to stimulate early spring growth.

If you plan to harvest wheat for a stored forage such as hay, baleage or silage, soil test each year and fertilize based on test results. Wheat harvest will remove nutrients from the soil.

If you plan to have livestock graze wheat in the fall, plant it in September or as early as your crop rotation and soil moisture allow. Be aware that this early planted wheat is at a greater risk for aphids, which can transmit barley yellow dwarf virus. Since the wheat is grazed by livestock when it is in a vegetative state, it should be protected from Hessian fly damage if only used for grazing.           

Plant wheat used for stored forages after the Hessian fly free date in October. This date varies each year but most often occurs by Oct. 15. Plant wheat two to 2.5 bushels per acre and 1 to 2 inches deep using a no-till drill into crop stubble or by broadcasting seed and lightly discing the ground to get the seeds at the proper soil depth.

Wait to turn livestock into wheat pastures until the plants are well established and at least 6 to 8 inches tall. Monitor fields for wetness and trampling of plants by the livestock. This is especially a concern during spring grazing. Only allow livestock to graze plants to 3 to 4 inches and allow the forage to recover to 6 to 8 inches long before grazing again.  Small grains fit well into rotational grazing systems as they recover and increase production similar to pasture grasses.

If you still want to get a grain crop from the wheat, only allow livestock to graze it lightly in the early spring. Do not graze wheat after plants reach the Feekes 6 growth stage, which is when the first node is visible above the soil surface and at the beginning of stem elongation. Grazing after this stage removes the growing point and prevents the seed heads from developing.  

For the best quality stored forages, harvest the crop at the boot to early head stage. Early cut wheat will ensile easier because it contains higher amounts of fermentable carbohydrates and forms denser bales. Feed early cut wheat to livestock with high nutrient needs like calves or lactating cows.

Nitrate poisoning is very unlikely under normal plant growth and weather conditions. However, periods of cool, cloudy weather, hail damage, frost and drought can cause nitrates to accumulate in wheat. The ensiling process removes about 50% of nitrates and reduces toxicity risk.

More information on using wheat for forage is available in the University of Kentucky publication AGR 263: Growing Wheat for Forage. It is available online at https://bit.ly/3eK5Z9x or by contacting the Warren County office of the UK Cooperative Extension Service.

2021 Annual Flower Garden Trial

The Warren County Extension Master Gardeners planted 20 new cultivars of annual flowers in May for the University of Kentucky Flower Trial Program. The University of Kentucky (UK) flower trial is a state-wide cooperative effort with the Master Gardener program to help evaluate performance of new flowering bedding plant cultivars in Kentucky. The main trial garden is located at the UK Arboretum in Lexington which contains 35 bedding plant cultivars.

Angelonia “Aria Purple”

Warren County is a trial site along with other counties including  Barren, Boyle, Breckinridge, Christian, Daviess, Hardin, Hopkins, Marshall, Mason, Mercer, Pulaski, and Washington.

The goal of the trial garden is to provide a fair evaluation of the garden performance for each flowering plant species and cultivar included.  To achieve this goal, it is necessary to use uniform cultural practices across the garden and to minimize environmental effects.

Pentas “Butterfly Red”

Extension Master Gardeners maintain the demonstration plots by watering and weeding the beds each week. Twice each month from mid-May until October, they rank the flowers on a scale of 0 to 5 with “5” being the best and “0” being the poorest.  

Lantana “Havana Sunset”

Here are some of the annual flower varieties that you will find in the 2021 growing season.

Bidens “Bidy Gonzales Top”
Canna “Cannaova Yellow”
Canna “Cannaova Red”
Lantana “Havana Harvest Moon”
Pentas “Butterly Light Lavender”
Catharanthus “Tattoo Papaya”
Catharanthus “Tattoo Cherry”

Buy Kentucky Fresh from Local Farmer’s Markets

Local foods tastes better. Fruits and vegetables grown  locally and sold at the farmer’s market spend more time maturing in the field, and less time on the road.

Tips for shopping at the farmers’ market

· Mind your budget. Before you go, decide how much you have to spend. Bring along a calculator or paper and pencil to track spending. Don’t buy more that you can store safely and eat or preserve before it spoils.

· Bring the kids and let them help pick out some of the fruits and vegetables. They will learn how to shop wisely and might even get excited about trying new foods.

· Arrive early for best selection. Popular items may sell out fast.

· Shop late for best prices. Some farmers will sell items at a lower price, rather than taking them home. Don’t be afraid to bargain.

· Make a lap around the market before making  purchases.  This will allow you to see which booths have the best quality food for the lowest prices, which vendors accept EBT or nutrition program benefits, or offer promotions such as Double Dollars.

· Keep an open mind. Produce sold at the farmers’ market is usually grown for taste, not appearance. It may look imperfect, but taste great.

· Ask for seconds. Sometimes farmers have good     produce that didn’t look good enough to display. Ask if they have seconds that they will sell at a reduced rate.

· Buy fruits and vegetables in season. That’s when they’re at the height of quality and lowest price. See below for information for when produce is in season.

· Ask questions. Farmers are usually happy to answer questions about their produce, and they often have good cooking and serving suggestions.

· Take notes to help you remember which vendors have good prices on high quality food. Next time you visit the market, refer to your notes.

· Buy now, enjoy later. If possible, buy large amounts of produce in season and freeze, can or dry it for the winter. Contact your county Extension office for   classes in food preservation.

Flies and Pink Eye a Problem Again This Summer

By Ric Bessin and Jonathan L. Larson; UK Entomology Extension Specialists

Face flies are annoying pests for cattle that can impact the animal’s welfare by just constantly molesting the eyes of our animals. These flies are looking to feed on tears but will also feed on saliva, blood, and nasal discharges. They do this by using their unique mouthparts, which resemble sponges and help them consume their liquid foods. Recently, county Extension agents informed us that they have received a large influx of questions regarding the connection between these pests and their transmission of pink eye.

Identification & Life cycle

Face flies look very similar to house flies in shape and coloration but are slightly larger than their close relative. They are dark grey with four black stripes that run down their back. As with a lot of flies, the maggots develop in fecal material. Specifically, face fly maggots develop in freshly deposited cattle manure. The maggots will hatch from eggs and then go through four stages of development over 15 to 25 days, depending on the weather. During the summer, face flies are not often found in structures, but the adults do overwinter in barns or attics and will become active again in the spring to start the next generation of flies.

Adults can be found resting on plants and fences when not on animals. (Photo: Whitney Cranshaw, Colorado State University, Bugwood.org)

Pink Eye Transmission

High numbers of face flies are associated with higher rates of pink eye issues. The feeding style of the flies causes more avenues of introduction by scratching the eyes, and the flies have been demonstrated to carry the causative agent of pink eye as well. Some estimates put the cost of pink eye in cattle at about $150 million annually.

Management Must Be Multifaceted

Fly control is essential, but can be difficult as face flies are only on the animal for a small percentage of the time. Therefore, addressing the egg and larval stages of the fly, as well as the adults, is most effective. A moderate to heavy fly infestation is when there are 10 to 20 flies per animal during the middle of the day. A single fly-control program will not work on every farm, so it often takes multiple tactics of control to achieve good results.

Fly tags (mid- to late May, through mid-September-October)(one ear tag or session or two sessions; be sure to use the number of tags required by the manufacturer), insecticide pour-ons, back rubbers (no 2 diesel), dust bags and knock-down sprays (Bachpack or ATV) are helpful in reducing the number of adult face flies on your animals. Fly traps in barns can also be helpful in reducing the number of flies. Feed additives with insect growth regulators are available that target the maggots that are laid in the manure. Encouraging dung beetles, which break down the manure pat, will also decrease egg survival.

Face flies can develop resistance to pesticides over time, so switching the drug mode of action of pesticides used every year is important. For example, if pyrethrins are used one year, then organophosphates should be used the following year. Waiting until the start of fly season to apply fly tags and removing the old fly tags in the fall also decreases the development of resistance. It is also extremely important to follow the safety precautions recommended by the manufacturer, as these insecticides can be toxic to people if handled improperly.

Appropriate grazing, along with clipping pastures will prevent seed-head development, reducing the irritation to the eyes of cattle, as well as reducing the resting areas for the flies. Clipping pastures to a low stubble height in May just after the seed heads emerge and again in mid-summer when weeds appear is recommended. Shaded areas need to be available to decrease the ultraviolet (UV) exposure and, in Herefords, breeding for pigmented eyelids has been successful, as this is a heritable trait. A good management program, including an appropriate vaccination program [especially infectious bovine rhinotracheitis (IBR) and bovine viral diarrhea (BVD)] and having good quality nutrition and minerals available at all times, will improve the overall condition of the cattle and decrease the incidence of this disease. Overhead hay feeders should be lowered and round bales should be rolled out. Ensuring adequate bunk space will decrease direct contact between the animals. Animals that develop pinkeye should be isolated if possible.
