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
Application type: Preplant or Preemergence
Sharpen powered by Kixor herbicide can be applied preplant surface, preplant incorporated, or preemergence to field corn, silage, or porcorn for broadleaf weed control. Some popcorn hybrids may be sensitive to Sharpen powered by Kixor herbicide. Check with seed supplier. Do not apply to corn that has emerged, or significant crop injury may result. The maximum rates of Sharpen powered by Kixor herbicide that can be applied to a coarse soil is 2.5 fl oz, medium soil is 3.0 fl oz, and to a fine soil is 3.5 fl oz. Sharpen powered by Kixor herbicide has excellent burndown activity of broadleaf weeds and must be applied with MSO at 1% v/v (minimum of 1.0 pt/acre) plus AMS 8.5 to 17 lb/100 gal or liquid nitrogen at 1.25 to 2.5 gal/100 gal. Sharpen powered by Kixor herbicide rate is affected by soil texture. Sharpen powered by Kixor herbicide may be tank mixed or applied sequentially with but not exclusively with Clarity, Guardsman Max herbicide, G-Max Lite herbicide, Verdict powered by Kixor herbicide, Oulook Herbicide, Prowl H2O, Status herbicide, Atrazine, glyphosate, Harness or Harness Extra. Sequential applications with Sharpen powered by Kixor herbicide or Verdict powered by Kixor herbicide require 14 days between applications. Do not apply more than 0.134 lb/acre saflufenacil (6oz of Sharpen) per cropping season. Do not use if organophosphate or carbamate insecticides were used at planting. Follow label directions.
