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

TREE FRUITS AND TREE NUTS (Trunk Spray or Preplant Dip)

Apply Nufos 4E to tree trunks and lower branches using a coarse, low-pressure spray to control pests listed in the following table. Use a higher rate in the rate range when there is increased pest pressure. Unless otherwise specified, a second application may be made after 2 weeks and a third application may be made after harvest. Avoid spray contact with foliage in sweet cherries as premature leaf drop may result. Consult your State Agricultural Experiment Station or Extension Service Specialist for proper application timing for your area.

Pest-Specific Use Directions:

- Preplant Dip Application (Peaches and Nectarines Only). For preplant control of peachtree borer, use Nufos 4E at the equivalent application rate of 3 quarts per 100 gallons of water. Dip trees several inches above the grafting bud scar and plant immediately or allow them to dry before returning to storage. Do not allow peach trees to remain in contact with the dip solution.

- For control of peach tree borer in established trees, apply before newly-hatched borers enter the tree. Use as a coarse, low-pressure trunk spray and thoroughly wet all bark areas from ground level to scaffold limbs. Do not allow spray to contact fruit. Consult written recommendations provided by your State Agricultural Experiment Station or Extension Service Specialist for proper time to treat in your area.

Specific Use Restrictions:

- Preharvest Interval: Do not apply within 14 days of harvest of almonds, peaches and nectarines or within 21 days before harvest of cherries.

- Do not make more than 1 chlorpyrifos application per year in peaches and nectarines and no more than 3 chlorpyrifos applications per year in cherries.

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

- Do not allow meat or dairy animals to graze in treated orchards.

3 pints/acre - peach tree borers

1.5-3 pints/acre - other pests

Restricted Entry Interval

4 days
