Comments and limitations

Controls cheatgrass and certain broadleaf weeds. Apply after wheat is in the 2-leaf stage but before jointing for control of small, actively growing weeds. Fall applications have provided better cheatgrass control than spring applications. Do not apply when wheat and weeds are dormant and not growing actively. Apply with NIS at 0.5% v/v. Liquid nitrogen fertilizer can be used at a maximum of 50% of the spray carrier volume. NIS should be used at 0.25% v/v when fertilizer is part of the carrier. Can be tank mixed with 2,4-D, Ally, Glean, Finesse, Express, Harmony Extra, bromoxynil, or MCPA. Wheat can be grazed immediately after application but should not be harvested for hay until 30 days after application. STS and IR corn can be planted 3 months after Maverick treatment if soil pH is less than 7.5 and cumulative precipitation exceeds 18 inches. Cotton and non-STS soybean can be planted 12 months after Maverick treatment if soil pH is less than 7.5 and cumulative precipitation is over 30 inches. Planting sorghum, non-IR corn, or sunflower is not recommended until at least 22 months after Maverick treatment. Rotation to other crops or with shorter interval requires successful completion of a field bioassay, and no sooner than 3 months after Maverick application. Risk of Maverick carryover is greatest on high pH soils.

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!
