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: Postemergence
Facet L herbicide, Quinstar 4L, or Quinstar GT can be applied to grain sorghum from emergence to 12 inches for control of field bindweed, foxtail, barnyardgrass, and morningglory. Best annual grass control occurs when applied with 0.5 to 1.0 lb atrazine, grass density is moderate to low, and plants are less than 2 inches tall. Field bindweed should be growing actively with runners at least 4 inches long. Always apply with MSO when applying alone or tank mixing with atrazine. NIS should be used if tank mixed with growth regulator herbicides. UAN or AMS can be added. The addition of 8.5 lb AMS/100 gallon will help control bindweed. Because of root uptake, rainfall following Facet L herbicide or Quinstar GT application may improve weed control.
