ASPARAGUS - PEST CONTROL

General Information

APPLICATION DIRECTIONS

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

ASPARAGUS - Pest Control

Apply as a ground broadcast foliar spray. Use sufficient volume of finished spray to ensure thorough coverage of crop foliage. Note: Nufos 4E may be applied aerially or with ground equipment for control of armyworms and grasshoppers.

Pest-Specific Use Directions:

1. For armyworms, asparagus beetles, asparagus aphids and grasshoppers, apply during the fern stage when field counts or crop injury indicates that damaging pest populations are developing or present.

2. For cutworms, it is preferable to apply when the soil is moist and worms are active on or near the soil surface.

3. For symphylans, apply at least two weeks before harvest for optimum control

Specific Use Restrictions:

- Do not make more than 1 preharvest application per season or apply within 1 day of harvest.

- Do not make more than 2 postharvest applications during the fern stage.

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

- For use only in the Midwest and Pacific Northwest states.

Pre-Harvest Interval

1 days

Restricted Entry Interval

24 hours
