Chemical selector
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!

Apply preplant up to 14 days before planting through preemergence for control of small-seeded grasses and pigweeds. Weak on large-seeded broadleaf weeds. May be tank mixed with glyphosate, paraquat, or 2,4-D for enhanced burndown control in no-till. Do not apply in counties west of U.S. Highway 281. Do not rotate to wheat for 4.5 months, corn for 10 months, or grain sorghum for 18 months after application. Do not apply additional fomesafen product in the same season and only use in alternate years.
