Agricultural information for growers and producers in Virginia's Northern Neck
Stripe Rust found at Warsaw, VA
On Friday, 4/27/18, Stripe Rust was confirmed in wheat plots at the Eastern Virginia AREC in Warsaw, VA. The disease was found on Southern States 520. Growers on the Northern Neck should begin scouting their fields for Stripe Rust. If it is found on a susceptible variety, a fungicide application is recommended.
Management recommendations, including variety susceptibility ratings and a fungicide efficacy table for stripe rust from Extension Plant Pathologist Dr. Hillary Mehl can be found here: http://blogs.ext.vt.edu/ag-pest-advisory/stripe-rust-found-in-north-carolina-wheat/

Small Grains Freeze Damage
The weather forecast calls for the temperature in areas of the Northern Neck to drop to as low as 31⁰F on Friday morning April 20. In Warsaw, temperatures are projected to be at or below 32⁰F from 3 am to 7 am. There is also a freeze watch for areas back west of Interstate 95. While some early planted wheat on the Northern Neck is just at boot stage, the majority of wheat is not there yet. Early maturing barley is starting to head, however. Wheat and barley that is early maturing is what is most susceptible to a spring freeze this time of year.
At boot stage, small grains are most susceptible to freeze injury when temperatures are at 28⁰F for two hours. At heading, injury can occur when temperatures are at 30⁰F for two hours. Primary symptoms of injury at these stages are white spikes, floret sterility, and leaf discoloration. It is important to check you small grains for injury at least 48 hours after the freeze event, as it generally takes this long for the damage to become evident.
