Excellent Weed Control for
Vineyards and Orchards.



Keep weeds under control with new Grapple™ Herbicide. Grapple delivers outstanding weed control on many crops, but it’s designed with the unique challenges of vineyards and orchards in mind. Count on Grapple to knockdown existing weeds and keep floors clean with lasting residual. Plus, Grapple is tank mix compatible with many pre-emerge herbicides for added weed control options.


FORMULATED FOR WEED CONTROL IN TREE AND VINE CROPS
  • Outstanding broad-spectrum pre- and post-emergent control of many weeds
  • Labeled for use on a wide range of crops, but formulated to deliver excellent results in vineyards and orchards
  • Long-lasting residual control

USE SUMMARY
CITRUS FRUIT, TREE NUTS, POME FRUIT, STONE FRUITS, GRAPES
Apply Grapple™ Herbicide as a uniform broadcast application to the orchard or vineyard floor or as a uniform band application directed at the base of the trunk or vine.

For broadcast applications: make a single application of Grapple at 4 ounces/A/year. For improved weed management, tank mix with other registered pre-emergence herbicides.

For banded treatments (50% band or less): Grapple may be applied twice a year. However, do not apply more than 4 ounces/A on a broadcast application basis per year. Unless otherwise specified on the product label, allow a minimum of 30 days between applications.

To help ensure uniform coverage, use a minimum of 10 gallons of spray solution/A. Nozzle selection should meet manufacturer’s spray volume and pressure instructions for pre-emergence or post-emergence herbicide applications.
Do not apply Grapple by air. Use ground application equipment only.

Apply only to crops that have been established for one full growing season and are in good health and vigor.

Best results are obtained when the soil is moist at the time of application, and ½ inch of rainfall or sprinkler irrigation occurs within 2 weeks after application. Time the application(s) to take advantage of normal rainfall patterns and cool temperatures. Moisture for activation should occur within 2-3 weeks after application.

Grapple may also be applied by certain chemigation methods, such as micro-sprinkler. However, do not apply by overhead, flood, or drip irrigation.

Avoid direct or indirect spray contact with crop foliage or fruit, except undesirable suckers.

Do not use Grapple in a spray solution with a pH below 4.0 or above 8.0 with spray additives that buffer the pH to below 4.0 or above 8.0, since degradation of Grapple may occur.

PRE-HARVEST INTERVAL (PHI)
Citrus Fruit (Crop Group 10) - 3 days
Pome Fruit (Crop Group 11) - 7 days
Tree Nuts (Crop Group 14) - 14 days
Stone Fruit (Crop Group 12) - 14 days
Grapes - 14 days

See label for complete directions for use.


PRECAUTIONS AND RESTRICTIONS
Direct sprays to minimize spray contact with fruit or foliage.

Avoid spray drift to any adjacent crops or desirable plants as injury may occur.

Draining or flushing equipment on or near desirable trees or other plants, or in areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots may injure these plants. Trees or desirable plants whose roots extend into a treated crop use area may be injured.

For best results, maintain spray tank solution at pH 5 to 7.

If the selected companion herbicide has a ground or surface water advisory, consider the advisory when using the companion herbicide.

Crop injury may occur from applications made to poorly drained soils.
