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: Corn
Application type: Preplant or Preemergence
Lumax EZ is a premix of 2.49 lb S-metolachlor (Dual II Magnum), 0.268 lb mesotrione (Callisto), and 0.935 lb atrazine (a restricted-use pesticide). Use the 2.7 qt rate when organic matter is less than 3.0% and 3.25 qt when organic matter is 3% or greater. Apply up to 14 days before planting or preemergence. Controls a wider spectrum of weeds than Bicep, especially velvetleaf, pigweed, and waterhemp, if properly activated. Can rotate to winter wheat 4.5 months after application and to cotton, soybean or sorghum the following spring. Application to sands and loamy sands where the water table is near the surface may result in groundwater contamination. Follow atrazine rate limits and label directions. No-till: May be tank mixed with Gramoxone SL, glyphosate, or a 2,4-D product (see 2,4-D label for restrictions) for preplant burndown of existing weeds. May be applied in liquid fertilizer before corn emerges. Follow label directions.
