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: Sorghum
Application type: Preplant or Preemergence
Degree Xtra and Fultime NXT are restricted-use herbicides. May be applied preplant incorporated, preplant surface, preemergence surface, or postemergence surface to grain sorghum (grain sorghum is a supplemental label and must use safened seed). The rate used in sorghum is dependent on soil texture and organic matter. If atrazine has been used early preplant, do not exceed a total of 2.5 lb atrazine active ingredient per calendar year. When applied to sorghum planted in alkali, eroded, or calcarious soils, crop injury may result. May be applied postemergence to sorghum up to 11 inches tall. Must be applied preemergence to emerging seedling grasses for adequate control.
