General Information


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.

Aerial Application

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.

Limitations, Restrictions, and Exceptions

SUGARBEET - Broadcast Application (Grasshopper)

Postemergence Treatment

Apply specified rate as a broadcast or banded foliar spray. Treat when field counts indicate that damaging insect populations are developing or present.

Broadcast application: Apply the specified dosage in water using 2 to 5 gpa of finished spray when using aerial spray equipment or 10 to 30 gallons of water per acre when using ground spray equipment.

Chemigation: Nufos 4E may be applied through sprinkler irrigation systems at listed broadcast application rates to control listed foliar pests. See Chemigation (Sprinkler Irrigation) Section for application instructions.

Pest-Specific Use Directions:

Grasshoppers: The low rate will control small nymphs (1st through 3rd instar).

Sugarbeet root maggot adults: Apply anytime from 7 days before until 3 days after peak adult emergence in order to target adults present at time of application based on local field trap monitoring.

To prevent potential development of insecticide resistance in sugarbeet root maggot, producers are encouraged to take the following steps: (1) avoid making more than 2 applications of Nufos 4E per season when adults are active; (2) if an organophosphate insecticide was applied at planting, make no more than 1 postemergence application of Nufos 4E when adults are active.

Specific Use Restrictions:

- Do not make a second application of Nufos 4E or other product containing chlorpyrifos within 10 days of the first application.

- Maximum single application rate is 1 lb ai chlorpyrifos per acre.

- Do not allow meat or dairy animals to graze in treated areas or harvest treated beet tops as feed for meat or dairy animals within 30 days of last treatment.
