Authority® Assist
The Foundation Preemergence with Grass Assist for Higher Yielding Soybeans
Authority Assist stops small-seeded broadleaf weeds and grasses before they start – before they steal yield at season’s end. Grass Assist means you can make more timely – effective – Roundup® application in your Roundup Ready® soybean system. In addition, Authority Assist rules against glyphosate-tolerant summer weeds like lambsquarters, pigweed, nightshade, morningglory and kochia.
- Delivers multiple modes of action
- Excellent solubility works across variable soil, residue, and moisture conditions for more consistent performance
- No pH restrictions fits multiple soil types and geographies, with very low risk for carryover to corn
- Grass Assist provides added grass control for a broader spectrum foundation product
- Superior crop safety for greater yields
“Authority Assist is cleaner than the competition and we needed a product that gave us flexibility in our corn seed rotation.”
