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
Apply Bicep Lite II Magnam and Cinch ATZ Lite only if field is planted with Concep-treated sorghum seed. These are mixtures of 2.67 lb atrazine (a restricted-use herbicide) and 3.33 lb S-metolachlor for use by growers wanting to reduce rates of soil-applied atrazine. This premix is recommended for sensitive watersheds, where atrazine best management practices suggest using no more than 1.0 lb atrazine/acre for soil surface applications at planting time. Use only on sorghum with Concep seed treatment. Follow atrazine set-back guidelines and label directions.
