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: Soybean
Application type: Postemergence
Restricted use pesticides. Apply only to Xtend soybeans from emergence through the R1 growth stage but before 45 days after planting for control of susceptible broadleaf weeds less than 4 inches tall. Non-Xtend soybeans will be severely injured or killed. Should be part of a planned weed control program following residual preemergence herbicides. Some crops such as non-Xtend soybeans are extremely susceptible to off-site movement of dicamba, so follow label guidelines near susceptible crops and sensitive areas. Do not spray when wind is blowing in direction of neighboring susceptible crops, including non-Xtend soybeans, and observe buffer guidelines. Only spray between 1 hour after sunrise and 2 hours before sunset when wind speed is between 3 and 10 mph. Do not spray during a temperature inversion. Do not apply with ammonium sulfate, which greatly increases the risk of volatility and vapor drift. Consult labels and respective websites for additional application guidelines and approved tank-mix combinations: xtendimaxapplicationrequirements.com for Xtendimax; fexapanapplicationrequirements.dupont.com for FeXapan; or engeniatankmix.com for Engenia.
