2016 Stripe Rust Survey

Stripe_rust_on_wheat Rust was discovered early this year in Texas moving up to Oklahoma and Kansas and has now been found in Colorado. Stripe rust will spread most readily in 50-60 degree temperatures especially during wet rainy weather, which is what eastern Colorado will likely see over the course of the next 1-2 weeks. The disease spread is still likely up to 65 degrees and is possible at 70 degrees. Windblown spores will germinate at night when the temperatures and leaf moisture condition are right.  Spore formation is stopped when daytime temperatures exceed 80 degrees. There are three different types of rust which includes stem, leaf, and stripe rust. Information on the three different rusts can be found here. To help us efficiently communicate the spread of stripe rust during the 2016 growing season we have created a survey that can be used to notify us of rust found on your crops. If you have found rust in your area please take a few minutes and complete the survey so we can help keep those in your area and across the state updated on the pathogen. Don’t worry if you cannot answer all the questions, but try to answer as many as possible. Kirk  D.
