Dimetric® EXT

Broad-spectrum Weed Control

Versatile grass and broadleaf weed control

Dimetric® EXT herbicide controls a broad spectrum of broadleaf weeds and grasses in a wide range of field crops, including corn and soybeans. A member of the triazine family, Dimetric® EXT herbicide contains the active ingredient metribuzin in a dry flowable formulation. This effective herbicide, which may be applied to the soil or postemergence, is taken up by the roots or through foliage, working as a photosynthetic inhibitor.

For extra convenience, Dimetric® EXT herbicide may be used with liquid fertilizers, impregnated on dry bulk fertilizer and chemigated (in certain crops). It also can be tank mixed with various other crop protection products. Application methods include ground or air (certain crops).

Weeds controlled

Dimetric® EXT herbicide controls a broad spectrum of broadleaves and grasses. In fall applications, it controls common chickweed, henbit, purple deadnettle and other winter annuals. And, it can be tank mixed with many other herbicides for fall or spring burndown applications prior to corn and soybeans.

Adjuvant Use

Urea ammonium nitrates, ammonium sulfates and nonionic surfactants may be used with Dimetric® EXT herbicide tank mixes applied postemergence in field corn. Adjuvants, including oils, may be used for fall or spring burndown prior to corn or soybeans, depending on the tank-mix partner. Depostion adjuvants such as InterLock® adjuvant may also be used. See the product label for adjuvant recommendations and restrictions.

8 x 5-pound bags


Refer to the label for specific weeds controlled and rates of application. Rates are determined by crop, organic matter, application timing, pH, region and other factors.

Application timing depends on the specific crop, but is generally preemergence or postemergence. For corn and soybeans, Dimetric® EXT herbicide can be applied in the fall, preemergence, postemergence or in split applications.
