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!

Crop type: Corn

Resource is used mainly in tank mixes to enhance velvetleaf control. It can be applied from the V2 to V10 stages (2 to 10 leaf collars visible) of corn. Use 2 oz for velvetleaf up to 4-leaf stage and 4 oz for velvetleaf at 6-leaf stage. Resource tank mixed with atrazine, Accent, Beacon, or similar products must be applied with 1 pt/acre COC and AMS at 2.5 lb/acre or UAN at 1 qt/acre can be added. Resource mixed with 2,4-D amine, Stinger, or dicamba must be applied with 0.25% NIS. Resource mixed with Buctril, 2,4-D ester, or dicamba + atrazine must be applied without the addition of an adjuvant. See label for mixing order recommendations and directions for drop nozzle application. Follow label directions.
