General Information


This product is a herbicide for use in cotton, fruit, nuts, golf courses, turf, grass seed crops, forestry, and non-crop areas. This product contains a surfactant (wetting agent). Additional surfactant may be required depending on the application spray volume. Local conditions and recommendations vary; consult local agricultural experiment station or extension service weed specialists for recommendations in your area.

See Golf Course and Turf Uses for weeds controlled at those sites.


This product should be applied with a low-volume, low-pressure, properly calibrated sprayer having satisfactory pumping and bypass action. For ground directed spray applications adjust nozzles in a manner to allow maximum coverage of weeds (and in a manner to keep spray off cotton foliage). DO NOT apply with hose-end applicators. This product is somewhat corrosive to certain metals; therefore, use in galvanized steel or aluminum equipment is not recommended.

For aerial application with fixed-wing aircraft or helicopter application, an exactly even swath deposition cannot be achieved, and consequently crop injury or pesticide nonperformance may result wholly or in part. Do not apply by air during periods of thermal inversion.

Apply during warm weather when weeds are in an active stage of growth. Adequate coverage is very important for effective weed control.

Limitations, Restrictions, and Exceptions


GENERAL INFORMATION ON TREE CONTROL: This product is designed for crown kill of undesirable trees through spaced-cut injection methods.

It is useful for the control of the following conifers: Cedar, Douglas fir, Grand fir, Lodgepole pine, Ponderosa pine, Jack pine, Red pine, Silver fur, and Western hemlock. It is also useful for the control of Big leaf maple, but not most hardwoods. It shows negligible translocation through root grafts and has no residual phytotoxic action in the soil. Forked trees require individual treatment.

CARE OF EQUIPMENT: This product is entirely soluble in water. Rinse all injection equipment thoroughly after use.


SPACED-CUT INJECTION WITH ANSUL “HYPO-HATCHET” INJECTOR: The Ansul HYPO-HATCHET injector cuts and injects in one operation.

When a tree is struck with the injector, a pre-set amount of this product is injected automatically into the sapstream of the tree immediately after impact.

The injector works by inertia and is designed to inject at least 1 milliliter of chemical per stroke. The cuts should be evenly spaced around the trunk to give proper distribution into the sapwood. For detailed instructions on how to use the Ansul HYDRO-HATCHET injector, refer to the Operation Manual.

CONIFERS (See General Information on Tree Control) AND BIG LEAF MAPLE (Growing Season): For trees less than 8 inches diameter at breast height (DBH), make one cut per 2 inches of DBH (4-1/2\" spacing between cut edges) at waist height or below. For trees 8 inches DBH and larger, make one cut per 1 inch DBH (1-1/2\" spacing between cut edges).

CONIFERS (Dormant Season): Make one cut per 1 inch of DBH (1-1/2\" spacing between cut edges) at waist height or below.

BIG LEAF MAPLE (Dormant Season): Make a complete frill at waist height or below (cuts need not be overlapping).
