CORN (FIELD, SWEET AND GROWN FOR SEED) - POSTEMERGENCE APPLICATION (1.5-2 pints/acre)
Broadcast Foliar Application
Apply with conventional power-operated spray equipment using nozzles and spray pressures recommended for insecticides. Apply Nufos 4E in a spray volume of not less than 2 gallons per acre for aerial application equipment (fixed wing or helicopter) or not less than 10 gallons per acre for ground equipment, unless otherwise specified. Increase spray volume to ensure adequate coverage with increased density and height of crop canopy. See Spray Drift Precautions section for recommendations on droplet size.
Ground Application: Orient the boom and nozzles so that uniform coverage is obtained. The swath width should not be wider than the boom. Follow nozzle manufacturer’s recommendations for insecticide nozzles with respect to nozzle type, pressure, and spacing.
Broadcast Soil Application
Apply with conventional power-operated spray equipment that will apply the product uniformly to the soil surface. Use nozzles that produce medium or coarse droplets (235-400 microns). Unless otherwise indicated, a spray volume of 10 gallons or more per acre is recommended. For band application, use proportionally less spray volume.
Use a minimum spray volume of 2 gallons per acre and follow recommendations for best management practices for aerial application, above.
Marking of swaths by flagging, permanent markers or use of GPS equipment is recommended.
Chemigation (Sprinkler Irrigation)
Nufos 4E may be applied to the following crops through sprinkler irrigation equipment: alfalfa, citrus (orchard floors only), corn (field and sweet), cotton, cranberry, mint, sorghum, soybeans, sugarbeet, orchard floors (almond, pecan and walnut), and wheat, or other crops as specified in Cheminova supplemental labeling. Do not apply this product by chemigation unless specified in crop-specific directions in the label or Cheminova supplemental labeling. Do not apply to labeled crops through any other type of irrigation system.
Note: Unless otherwise indicated in specific use directions, the application rates for chemigation are the same as those recommended for broadcast application.
CORN (FIELD CORN AND SWEET CORN, INCLUDING CORN GROWN FOR SEED)
Conservation Tillage: Preplant, At-Plant, or Preemergence Applications
Apply as a broadcast spray to the soil surface using power-operated ground spray equipment. Use a total spray volume of 20 gpa or more. Use a higher rate in the rate range to extend residual control.
Tank-Mixing: Nufos 4E may also be applied in tank-mixtures with paraquat or glyphosate and/or liquid fertilizer solutions. See Mixing Directions section for tank mixing instructions. Read and carefully follow all applicable directions, restrictions, and precautions on labeling for each product used in combination with Nufos 4E.
Apply as a postemergence broadcast spray using sufficient spray volume to ensure thorough coverage of treated plants, but no less than 15 gallons per acre (gpa) for ground spray equipment or 2 to 5 gpa for aircraft equipment. Control may be reduced at low spray volumes under high temperature and wind conditions. Nufos 4E may be tank-mixed with glyphosate products such as Glyfos herbicide when application is to be made to glyphosate-tolerant corn. Note: Do not apply aerially in Mississippi.
Chemigation: Nufos 4E may be broadcast applied postemergence through sprinkler irrigation systems at listed application rates to control listed foliar pests. For best results, tank-mix Nufos 4E with 2 pints of nonemulsifiable oil. See Chemigation (Sprinkler Irrigation) section on the product label for application instructions.
Pest-Specific Use Directions:
For southwestern corn borer, a second application may be applied 21 days later if needed due to reinfestation.
Specific Use Restrictions:
- Do not make a second application of Nufos 4E or other product containing chlorpyrifos within 10 days of the first application.
- If more than 1 lb ai granular chlorpyrifos per acre is applied at-plant (for a maximum of 1.3 lb ai per acre per season), only 1 additional application of a liquid product containing chlorpyrifos at 1 lb ai per acre is allowed per season, for a total of 2.3 lb ai chlorpyrifos per acre per season.
- Do not apply in tank-mixes with Steadfast or Lightning herbicides.
