Authority 480 is a pre-plant/pre-emergence solution for broadleaf control. It can be applied with or without glyphosate and will alleviate pressure from the first flush of weeds and help make post emergent weed control more effective. Authority’s broad spectrum control and excellent crop safety make it an ideal component in an IP program.
