The Pesticide Selector includes suggestions for chemical control of pests in Kansas crops, which are provided by K-State Research and Extension, and may not be relevant for states other than Kansas. We will continue to expand this tool for help in selecting other types of agricultural chemicals, and for other states. Contact the myFields Team if you are interested in contributing content!
