A new computer program developed by University of Idaho weed scientists for dryland farmers in northern Idaho, eastern Washington and eastern Oregon is designed to simplify herbicide selection and prevent development of herbicide resistant weeds and damage to future crops.
Weed scientists Donn Thill, Joan Campbell and Traci Rauch developed the program. Weed scientist Don Morishita at the Kimberly Research and Extension Center is working to expand the program's use to southern Idaho irrigated crop rotations.
"The goal is to help growers make decisions about which herbicide might best control weed problems and fit into their crop rotations," said Thill, a professor of weed science and superintendent of the Palouse Research, Extension and Education Center at Moscow, Idaho.
The program, "Herbicide Resistance and Persistence Management," is available on a free trial basis to growers. Growers who decide to use the program will be charged a $50 annual subscription fee to cover updates.
