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 Italian (annual) ryegrass. Apply to actively growing weeds after wheat emergence but before the jointing stage of growth. Application before wheat tiller initiation have a greater risk of stunting the crop. Must be applied with MSO or NIS plus nitrogen fertilizer adjuvants. Topdress liquid nitrogen fertilizer applications are not recommended within 21 days of Osprey treatment because of the increased potential for crop injury. Can be tank mixed with Ally, Finesse, Harmony Extra, MCPA ester, or Starane. Do not plant barley, sunflower, soybean, or cotton until 90 days, corn 12 months, or any other crop until 10 months after Osprey application.
