BOISE, Idaho -- The University of Idaho says researchers have developed a computer program to help Pacific Northwest growers better choose herbicides to control weeds and prevent crop damage.
The university's College of Agricultural and Life Sciences says weed scientists worked with farmers in northern Idaho, eastern Washington state and eastern Oregon to develop the program.
Don Morishita at the UI Kimberly Research and Extension Center is working to expand the weed control measures into southern Idaho, helping growers there better manage unwanted weeds.
The goal of the program is to simplify the process and manage weeds that are resistant to herbicides.
Researchers say more than 200 types of weeds have showed resistance to common herbicides.
