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
Balance Flexx is a restricted-use pesticide. It is prohibited on fields that contain vulnerable sandy loam, loamy sand, or sand soils if the water table is less than 25 feet below the soil surface. See 24(c) label for list of vulnerable soils. Rate depends on soil texture, organic matter, pH, and aplication timing. The addition of atrazine will improve control. Balance Flexx may be tank mixed with many grass and broadleaf herbicides. Do not apply aerially or through any type of irrigation system. Corn seed must be planted at least 1.5 inches deep, completely covered with soil, and the seed furrow firmed. The rotational interval is 4 months for wheat, 6 months for soybean, sorghum or sunflower, and 10 months for alfalfa. No-Till: May be soil surface applied up to 21 days before planting field corn and up to 30 days before planting when used in a planned sequential application program. When applied with COC or MSO, Balance Flexx controls labeled weeds less than 3 inches in height. Tank mix with other burndown herbicides to control a broader spectrum of weeds or larger weeds. Tank mix with other residual herbicides to extend the spectrum and duration of control. Early Postemergence: Balance Flexx can be applied postemergence to corn in a tank mixture with atrazine (only) from spiking through the 2-collar leaf stage of growth. Do not apply with other herbicides, insecticides, fertilizers, or adjuvants, or crop injury including bleaching, leaf necrosis, and stunting may result. Follow label directions.
