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 but not wild buckwheat. The least injury to wheat can be expected if applied between full tiller (about 4 to 8 inches) and early boot stages. Likelihood of injury is increased if 2,4-D is applied to wheat in the fall when it is not tillered fully. Can be applied in nitrogen fertilizers. Do not apply when wheat is between early boot stage and milk stage. Do not allow grazing on treated fields within 2 weeks after treatment.
Can be used to control wild garlic (wild onion). The least injury to wheat can be expected if 2,4-D is applied after full tiller stage (when wheat is 4 to 8 inches tall) but before wheat plants elongate rapidly or enter joint stage. This rate will not consistently kill wild garlic, but it reduces production of aerial bulblets and knocks down tops of plants.
This is a tank mix of bromoxynil and 2,4-D. Can control wild buckwheat and other broadleaf weeds. Apply after tillering but before jointing stage. Apply before weeds are past 3- to 4-leaf stage or more than 2 to 6 inches tall. Do not allow grazing on fields for 45 days after application.
Apply to small, actively growing weeds after winter dormancy but before joint stage of wheat. Controls wild buckwheat and other broadleaf weeds. Follow label restrictions for pasture and hay for lactating dairy animals.
Controls many broadleaf weeds. Apply with MCPA in the fall or spring after the 2-leaf stage but before the boot stage of wheat. Apply with 2,4-D in the spring after the wheat is fully tillered but before the early boot stage. Apply to small, actively growing weeds up to 2 inches soybean, IR corn, or proso millet for 4 months, barley or oat for 10 months, non-IR corn for 12 months, non-STS soybean for 12 to 34 months, or sunflower for 22 months after Ally application. Do not use on soil with pH above 7.9.
Controls many broadleaf weeds and wild garlic. Apply MCPA in the fall or spring after the 2-leaf stage of wheat but before the flag leaf is visible. Apply with 2,4-D in the spring after wheat is fully tillered but before the flag leaf is visible. Apply with NIS at 0.12 to 0.25% v/v to small, actively growing weeds. Use 0.75 to 0.9 oz/acre for wild buckwheat or wild garlic control. Does not provide residual weed control, but any crop can be planted 45 days after treatment. Do not feed forage from treated areas or allow livestock grazing within 7 days of application. Allow 30 days between application and feeding hay from treated areas to livestock.
