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: Wheat
Application type: Postemergence
Controls many broadleaf weeds. Apply after 2-leaf stage but before boot stage of wheat. Always apply with NIS at 0.25 to 0.5% v/v. Can be applied with liquid nitrogen fertilizer, but do not add surfactant if liquid fertilizer is the carrier. Use higher rate for wild buckwheat control and extended residual control. Tank mixes can improve weed control and reduce the risk of herbicide resistance problems. Finesse can be tank mixed with dicamba, Buctril, MCPA, Sencor, or 2,4-D. Do not apply to soils with a pH below 5.0 or above 7.9. In the western tier of Kansas counties, the maximum use rate is 0.3 oz/acre applied not more than once every 24 months, non-STS soybean for 14 months (east of Highway 183, west of Flint Hills), or any other crop until a field bioassay has been performed. STS soybean and IR corn hybrids can be planted 4 months after application if soil pH is 7.5 or lower. Refer to label for additional use and crop rotation gruidelines.
Finesse Grass & Broadleaf is a premix of chlorsulfuron (Glean) and flucarbazone (Everest) herbicides. Controls cheat, Japanese brome, Italian ryegrass, and many broadleaf weeds. Much less effective for downy brome than for cheat or Japanese brome. Apply in the fall to small, actively growing weeds after wheat is in the 2-leaf stage of growth but before grasses exceed the 2-tiller growth stage. Can be applied in liquid nitrogen fertilizer carrier. Apply with 0.25 to 0.5% v/v NIS plus 2 qt/acre liquid nitrogen fertilizer when applied in water carrier, 0.06 to 0.25% v/v NIS with up to 50% liquid nitrogen carrier, and with no NIS if applied in greater than 50% liquid nitrogen carrier. Application in liquid nitrogen carrier tends to increase cheatgrass control and the risk of crop injury. Do not use if soil pH is greater than 7.9. Do not replant wheat until 4 months after application. Do not rotate to soybean for 14 to 28 months depending on geography, soil pH, and cumulative precipitation. Do not rotate to other crops until the completion of a successful field bioassay. Consult the label for additional use and crop rotation guidelines.
