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
Provides residual control of grasses and certain broadleaf weeds. Apply preplant up to 45 days before planting or preemergence. Use the lower rates on coarse-textured soils and the higher rates on fine textured soils. Early preplant applications more than 15 days before planting are not recommended on coarse-textured soils or in higher-rainfall areas. Do not apply more than 2.1 oz/a Zidua or 3.5 oz Zidua SC on coarse-textured soils, 3.0 oz/a Zidua or 5.0 oz Zidua SC on medium-textured soils, or 3.5 oz/a Zidua or 5.75 oz Zidua SC on fine-textured soils per crop season. Does not provide control of emerged weeds. Soybean and corn can be replanted any time after Zidua application. Do not plant wheat or cotton for 4 months; sorghum for 6 to 12 months; alfalfa for 10 months; small grains other than wheat for 11 months; or any other crop for 18 months after Zidua application.
