Classic® Herbicide

Residual Activity and Control of Tough Perennial Broadleaf Weeds

With residual activity and control of tough perennial broadleaf weeds, DuPont™ Classic® herbicide is a popular choice for growers of IP, conventional and glyphosate-tolerant soybeans.

Controls tough broadleaf weeds: Classic® provides excellent control of late-emerging perennials like dandelion (top growth), yellow nutsedge, common ragweed, redroot pigweed and velvetleaf, as well as suppression of wild carrot and volunteer adzuki beans.

For one-pass control of both grassy and broadleaf weeds, tank-mix Classic® with Assure® II.

For crop rotations, refer to the label for specific planting intervals for various crops based on the pH level of your soil.
