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
Can control winter annual weeds such as cheat, downy brome, and mustards. Apply only on selected varieties of dryland winter wheat in fall or early spring. Wheat varieties differ in tolerance to metribuzin. Refer to the label for information on sensitive and tolerant varieties. Can be applied to wheat from the 2-leaf to jointing stage of growth, depending on application rate. Do not apply when wheat is in winter dormancy. Fall applications generally provide better cheatgrass control than spring applications. Can be tank mixed with 2,4-D, dicamba, bromoxynil, Ally, Amber, Finesse, Glean, Harmony Extra, or MCPA. Crop injury can occur from application to wheat that was seeded less than 1 inch deep, on coarse-textured soils, soils low in organic matter, calcareous soils, or soils with a pH above 7.7. Do not allow grazing on treated fields for 14 days after application.
