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
Resicore may be used on all field corn, grain, silage, or seed, and yellow popcorn from 28 days before planting prior to emergence. Resicore may be applied early postemergence to all field corn. See postemergence section for further discussion. When organic matter is less than 3% use Resicore at 2.25 qt on coarse soils, 2.5 qt on medium soils, and 2.75 qt on fine soils. When soils are 3% or more organic matter, use Resicore at 2.5 qt on coarse soils, 2.75 on medium soils, and 3 qt on fine soils. When applying Resicore as a split application, both pre and post, see label for restrictions and rates. A maximum of 3.25 qt can be used in the entire season. Weed control with Resicore will be enhanced when applied with atrazine. Rotational restrictions: wheat 4 months, alfalfa, barley, millet, oats rye, sorghum soybean, and sunflower 10.5 months. If applied with atrazine, restrictions to soybean is 18 months. If Resicore is applied after June 1, only corn or grain sorghum can be planted the following year.

Weed control with Resicore will be enhanced when applied with atrazine. Rotational restrictions: wheat 4 months, alfalfa, barley, millet, oats, rye, sorghum and sunflower 10.5 months; soybeans 10.5 to 18 months depending on atrazine combinations, soil pH, organic matter content and precipitation (refer to label). If atrazine tank-mix rate exceeds 2 lb/a, do not plant soybean for 18 months. If Resicore is applied in the High Plains region or after June 1, only corn or grain sorghum can be planted the following year.
