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
Controls annual broadleaf weeds. Broadcast apply when weeds are small and growing actively and sorghum is in the 2- to 5-leaf stage but before it is 8 inches tall. On sorghum from 8 to 15 inches tall, apply with drop nozzles to keep dicamba off leaves and out of whorls. Failure to observe these height guidelines can result in damaged seed heads. Do not apply to sorghum grown for seed. Do not allow grazing of treated areas or feed treated forage or silage before mature grain stage. Do not apply when the temperature on the day of application is expected to exceed 85 degrees F. Expect some crop response in the form of rolled-up leaves and leaning stems. The addition of AMS to a spray mixture containing dicamba will increase the risk of volatility of dicamba and mitigate the benefits of lower volatility of products like Clarity or DiFlexx.
