6 GENERAL DESCRIPTION:

A translocated, leaf and root absorbed, residual herbicide for the control of some woody weeds, sedges, perennial grasses and broadleaf weeds around buildings, pasture and in pine plantations.

7 APPLICATION METHODS AND TIPS:

This product may kill many trees and other desirable plants if not correctly applied.

Don't use near waterways or where water may leach herbicide to desirable species.

Don't use adjuvants for selective overall spraying.

Best results when applied to actively growing plants and temperature is greater than 250C. Symptoms may be slow to appear in cool weather.

For soil application, best results when applied to bare, moist soil and rain follows.

On slopes greater than 20-30 degrees apply as spot or strip treatment.

9 ADJUVANTS:

Don't use adjuvants for overall application on pines.
