Product quantity per acre
1.0 to 1.5 pt Kochiavore

Kochiavore can be applied to burndown broadleaf weeds, preplant to corn. Wait a minimum of 7 days before planting corn or apply preemergence after corn is planted in a no-till system. The seed furrow must be completely closed at the time of application or severe crop injury may result. Kochiavore can be applied to corn from V3 through V5 growth stage and a directed spray only from V6 growth stage up to 2 weeks prior to tassel. Do not cultivate for 7 to 10 days following treatment to avoid stalk breakage. DO NOT tank mix with atrazine, crop oils, or other adjuvants such as NIS.

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!
