The 2020 VA Ag Expo has been cancelled. The Ag Expo committee with guidance from the Virginia Soybean Association and Virginia Grain Growers Association have made this difficult decision to ensure the health and safety of exhibitors and guests as a result of the COVID-19 pandemic. We will be reaching out to each exhibitor and sponsor to discuss our next steps. We appreciate your support and look forward to 2021!
The Virginia Grain Producers Association has announced the rules and entry forms for the small grains yield contests. This is a great way to promote good small grain management and for top producers to be recognized.
CANCELLED! Due to Virginia Tech’s response to COVID-19 and out of concern for everyone, we are cancelling all of these workshops. We will reschedule after field season in Nov. or Dec.

The recent hot and dry weather is really drying the wheat down quickly. We harvested our first wheat today (the moisture was ranging from 16 to 20%) and planted soybean immediately afterwards. Just 2 days ago, the wheat grain moisture was in the mid-20’s!
That experiment is part of our ongoing efforts to harvest higher quality wheat and increase our double-crop soybean yields. Now, I’m not advising you to harvest your wheat at 20% unless you have a buyer that will take it, preferably without a discount, or you have a way to dry down quickly. High moisture wheat will heat up quickly and you will need to do something with it right away.
With that said, we have seen great benefits from harvesting higher moisture wheat and getting the soybean planted immediately. Our Mid-Atlantic regional project conducted from 2015 thru 2017 found greater wheat yields and test weight, and greater soybean yields. Our data is shown below. Note that I’m only showing Virginia wheat data as the date where yield began declining differed among the states (this data was earlier as we moved south), but the general shape of the graph was similar. Different colored symbols represent different years.
In summary, there is benefit from harvesting wheat and planting soybean as soon as possible. However, read the previous blog, To Plant or Not to Plant into Dry Soil, before making too many decisions. Not only is our topsoil dry, but the wheat may have removed moisture much deeper – giving us little total soil moisture.
Fusarium head blight (FHB) risk is continuing to increase in parts of Virginia. Upcoming rain events will increase risk over the next three days (see figure below). Much of the wheat in the southern part of the state is past the vulnerable flowering stage, but wheat that is at or about to enter flowering may be at risk. Consider applying a fungicide if risk is moderate to high, especially on susceptible or moderately susceptible varieties. Fungicides should be applied at early flowering or up to one week later. Do not apply a strobilurin-containing fungicide since this can increase DON contamination. Recommended fungicides include Prosaro, Caramba, Proline, and Miravis Ace. Increased incidence and severity of leaf blotch and powdery mildew have been observed in some fields, and these fungicides will also provide control of foliar diseases.
There is increased risk of Fusarium head blight (FHB) in some parts of Virginia, especially near the Northern Neck and Eastern Shore of Virginia. Wheat in much of the state is flowering, and if a field is in a high risk area a fungicide application is recommended. Recommended fungicides for control of FHB and DON contamination include Caramba, Prosaro, Proline, and Miravis Ace. Do not apply a strobilurin-containing fungicide after the flag leaf stage since this has the potential to increase DON concentrations in the grain. To maximize their effectiveness, fungicides for FHB and DON control should be applied at early flowering or up to one week later. Fungicides that control FHB and DON will also control foliar diseases including powdery mildew, leaf rust, stripe rust, and leaf blotch.
Wheat varieties vary in susceptibility to FHB and DON, and this should be considered when making decisions of whether or not to apply a fungicide at flowering for FHB control. The FHB Risk Tool (http://www.wheatscab.psu.edu/) allows you to select the susceptibility of your wheat variety to determine risk. You can find information on FHB susceptibility of your wheat variety from your seed dealer or in the Virginia Cooperative Extension Small Grains publication. The FHB Risk algorithm adjusts the relative risk based on the variety susceptibility as illustrated below. For assistance with small grains disease identification or for additional management recommendations contact Dr. Hillary Mehl, Extension Plant Pathologist (email@example.com).
Most of the wheat crop in Virginia is currently between flag leaf emergence and heading with some wheat close to the flowering stage. Foliar diseases including powdery mildew and leaf blotch have been observed in some fields, but overall levels of disease have been low so far. As wheat reaches the flowering stage, it is susceptible to infection with Fusarium head blight (FHB), and this is the critical stage for making fungicide applications. Currently, the risk for FHB infection is low throughout Virginia. In addition, the 3-day forecast indicates risk will remain low. FHB risk can be monitored using the Fusarium Risk Assessment Tool (http://www.wheatscab.psu.edu/).
Recommended fungicides for control of FHB and DON contamination include Caramba, Prosaro, Proline, and Miravis Ace. Do not apply a strobilurin-containing fungicide after the flag leaf stage since this has the potential to increase DON concentrations in the grain. To maximize their effectiveness, fungicides for FHB and DON control should be applied at early flowering or up to one week later. Fungicides that control FHB and DON will also control foliar diseases including powdery mildew, leaf rust, stripe rust, and leaf blotch. For specific wheat disease management recommendations or assistance with disease identification, contact Dr. Hillary L. Mehl (firstname.lastname@example.org).

A series of half-day workshops will be held in Maryland, Delaware and Virginia this winter for farmers interested in learning about the problems of herbicide resistant weeds and how to manage them. Hosted by University of Maryland Extension in collaboration with Virginia Tech and University of Delaware, these workshops are designed to equip farmers with the knowledge to improve weed control on their farms.
Farmers in the mid-Atlantic area are starting to see the impact of herbicide resistant weeds on their crop yields. With many problematic weeds now found throughout the region it is essential that farmers learn the key management strategies to control these weeds.
Sessions will cover integrated weed management tactics; palmer amaranth, common ragweed and marestail control strategies; and developing a weed management plan. There is no charge to attend and lunch will be provided. Pesticide (commercial and private) and CCA continuing education credits will be offered.
