Drone Fungicide Applications in Corn

3/12/2021 (new)
Authors: Ricky Arnett, Pat Hardesty, Nick Roy, Kiersten Wise

Foliar fungicide applications occur commonly in corn to manage foliar diseases such as gray leaf spot. University of Kentucky research indicates that the most effective application timing for both foliar disease control and yield benefits is at tasseling/early silking (VT/R1). Because of the height of corn at this growth stage, these applications are typically applied aerially, with fixed wing or helicopter aircraft. However, many Kentucky fields are small, surrounded by trees or other obstacles to aircraft, meaning that fungicide application is not an option in these areas.

Seedling Diseases of Corn

3/8/2021 (major revision)
Authors: Carl Bradley, Kiersten Wise

Corn seeds and seedlings are susceptible to infection by a number of soilborne fungi. When planted into cool, wet soils, seeds may decay before or after germination. Affected plants that survive past the seedling stage may go on to produce an ear if nodal roots develop normally, although stunting and reduced ear size can occur as a result of seedling diseases. Severely affected plants may die during stressful weather as the result of an inadequate root system.

Drone Fungicide Applications in Corn

3/5/2021 (new)
Authors: Ricky Arnett, Pat Hardesty, Nick Roy, Kiersten Wise

Drone technology has improved in recent years and has also become more accessible. In Kentucky, commercial drone fungicide application is now an option in several areas. Drones specifically designed to apply products can potentially be used to apply fungicide in fields that are not accessible to other aircraft. This publication describes experiments to determine if drone fungicide applications can reduce foliar diseases in corn and discusses factors to consider when using drone technology to apply fungicides.

Organic Corn Production in Kentucky

1/15/2015 (new)
Authors: Chad Lee, Will Martin, Sam McNeill, Lee Meyer, Michael Montross, Edwin Ritchey, Tom Sikora

The number of organic dairy cows in Kentucky has been steadily increasing for years, yet there's not enough organic corn produced in the state to feed the growing herds. In short, a new market has developed in the state, but few local farmers are taking advantage of it. While Kentucky farmers are no strangers to corn, growing corn organically utilizes different management, cultural and marketing practices and requires new skills. And, importantly, organic production must follow an approved farm plan that allows farmers to sell their corn as certified organic. This publication is designed to be both an introduction to a new enterprise as well as a practical manual for those interested in pursuing organic corn production on their own farms.

Corn for Grain and Silage

6/15/2013 (minor revision)
Authors: Matthew Ernst, Cheryl Kaiser

Corn for grain and silage can be produced for on-farm use and/or off-farm sale. There are a variety of local and regional markets for corn in Kentucky, such as local grain elevators. U.S. producers face international competition in the livestock category; corn prices have fluctuated greatly in recent years. Expanded corn markets, as well as the emergence of more uses for corn, could help stabilize future prices. In addition to animal feed, field corn uses include industrial (sweeteners) and energy (ethanol) products

Broomcorn

4/18/2013 (minor revision)
Authors: Matthew Ernst, Cheryl Kaiser

Broomcorn (Sorghum vulgare) is not actually corn, but is instead related to the sorghums used for grain and syrup (Sorghum bicolor). Broomcorn has a coarse, fibrous seed head that has been used to make various types of brooms and brushes for several hundred years. While there are still artisans creating these natural brooms today, this crop is now more commonly used to make decorative items, such as wreaths, swags, floral arrangements, baskets, and autumn displays. It takes about 60 sprays (heads) to make a broom, but wreaths and dried arrangements require only a few plants. Broomcorn is available in natural colors, as well as purple and various fall colors.

Authors: Don Hershman, Cheryl Kaiser, Paul Vincelli

Interest in the use of foliar fungicides for corn and soybean has expanded dramatically in the U.S. over the past few years, resulting in a major change in how these crops are being produced on many farms. Until recently, foliar fungicides for soybeans and corn were reserved for seed production fields to protect seed quality in very specific circumstances or for specialty crops. Applications for the purpose of protecting crop yield were rarely economical. However, the current trend in Kentucky, as well as many other corn/soybean producing states, is towards an increased use of foliar fungicides on these crops as a means of maximizing yields.

The Corn and Soybean Production Calendar was developed to help producers prioritize and schedule work events in a timely fashion on the farm. Weather events and equipment breakdowns rarely follow an organized schedule. However, if other practices within the farming operation are prioritized, perhaps a producer can better address the emergencies that will occur.

Estimating Hail Damage in Corn

7/27/2007 (new)
Authors: Chad Lee

Hail is precipitation in the form of irregular shapes of ice. Hail can shred leaves off corn plants, bruise stalks, and turn a beautiful field of corn into bare stalks with a few ragged leaves. The initial sight of hail damage is sickening to any farmer. Small corn, with the growing point below the soil surface (see corn staging below) is highly tolerant to hail damage. As the growing point moves above the soil surface and the corn plant gets closer to tasseling, corn becomes more susceptible to hail damage. Corn is most susceptible to hail damage from the period just prior to tasseling through early milk. Once corn passes the early milk stage, it becomes more tolerant to hail damage.

Authors: J.D. Green, Jim Herbek, Chad Lee, Jim Martin, Paul Vincelli

Evaluating damaged corn stands and determining when to replant is often a difficult task. Survival, health, and expected yield of the current stand must be weighed against replanting costs, additional management, and expected yield of a replanted crop. The options are rarely clear-cut because damaged corn is rarely uniform throughout the field. The following information will help when making evaluations and management decisions.

The corn grown in Kentucky is used mainly for livestock feed and as a cash crop. As a cash crop sold from the farm, corn ranks third behind tobacco and soybeans but is the number one row crop in terms of acreage. Because the cost of producing an acre of corn is high and the value per bushel has declined in recent years, producers must manage and market their corn crop more carefully for adequate profits. The goal of this publication is to serve as a guide for corn production strategies that focus on efficient use of resources and provide the principles and practices for obtaining maximum, profitable corn yields.
