Product Overview
Authority® 480 herbicide is a powerful, flexible Group 14 herbicide that’s ideal for fall application. Applied with or without glyphosate, it provides extended activity on challenging weeds like kochia, redroot pigweed, lamb’s-quarters, wild buckwheat and cleavers.
Authority® 480 herbicide requires moisture to be activated. By applying in the fall, it will move into soil water with the snowmelt and/or an early spring rainfall, becoming available for uptake by emerging weeds. By controlling weeds before they emerge in the spring, there’s less competition for water and nutrients. That means a better start for your crop.
Many weeds are now resistant to one or more herbicide Groups. As a Group 14, Authority® 480 herbicide is active on the following resistant weeds: redroot pigweed (Groups 2 and 5), lamb’s-quarters (Group 2), cleavers (Groups 2 and 4), kochia (Groups 2 and 9) and wild buckwheat (Group 2).
One jug of Authority® 480 herbicide treats 32 acres to 43 acres, with a convenient concentrated formulation, compared to 80 acres for one large tote of competitive granular herbicide.
