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: Postemergence
Liberty 280 SL is a nonselective herbicide for use over corn designated as Liberty 280 SL Link or corn warranted by Bayer CropSciences as being resistant to Liberty 280 SL. Optimum weed control is a chieved by applying with atrazine or Laudis Herbicide when weed height is 1 to 4 inches and corn height is less than 12 inches. May be applied without atrazine to corn up to the V7 stage (7 leaf collars visible) or until corn is 24 inches tall (freestanding), whichever comes first. Liberty 280 SL is primarily a contact herbicide, so thorough spray coverage is important. For best results on crabgrass, sandbur, and yellow foxtail, apply before tillering. Always condition water carrier with spray-grade AMS at 3 lb/acre before adding Liberty 280 SL to the spray tank. Do not add surfactants. See label for rate guidelines, according to weed species and size. Liberty 280 SL is foliar active and has no soil activity. Unless weed pressure is light, apply over a soi-residual herbicide, or apply twice in a season. Follow label directions.
