Product Overview

Authority 480 herbicide is a powerful, flexible pre-emergent Group 14 herbicide that provides extended activity on challenging broadleaf weeds in soybeans and many other crops.

Authority 480 herbicide can be applied alone or can be tank-mixed with glyphosate and other registered partners. Its convenient liquid formulation ensures ease of use and mixing.

Ideal for IP soybeans, Authority 480 herbicide controls many of the most troublesome weeds you face. These include lamb’s-quarters, pigweeds, Eastern black nightshade and common waterhemp. Plus, it works well with herbicide-resistant soybeans, too.
