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: Soybean
Application type: Preplant or Preemergence
Controls many annual weeds in soybean in and east of Jewell, Mitchell, Lincoln, Ellsworth, McPherson, Harvey, Sedgwick, and Sumner counties. Apply preplant (up to 45 days before planting) and incorporate with two passes in top 2 inches of soil. Preemergence application can be effective if enough rainfall to wet the soil to a depth of 2 inches is received within 7 days of planting. Wheat can be planted after 4 months. Field corn can be planted after 9.5 months if 15 inches of rainfall were received from 2 weeks before application through November 15. Do not allow grazing and do not feed treated soybean forage.
