Hand-Held Equipment:

Thorough saturation of the foliage and stems is required for control, but stop sprays when run-off from weed leaves occurs.

Use low spray pressure to reduce foaming and avoid contact with desirable plants.

Most spray nozzles are designed to operate at 10 to 15 psi and provide uniform spray coverage of weeds.


Directed Spray Equipment:

Use a shielded sprayer to prevent spray contact on desirable plants.


Spot or Directed Applications:

This product may be used as a spot or directed spray application

DO NOT apply beyond runoff. Ensure uniform and complete coverage.

Use a coarse spray.

DO NOT spray during windy conditions. Backpack, pump-up and hydraulic sprayers may be used. Thoroughly clean the sprayer following use.
