Authority First Recommendations Timing for Fall Applications – Optimum residual activity is obtained when fall applications are delayed until soil temperatures are 50°F or cooler, which generally occurs after mid-October in many areas. Timing for Spring Applications – Spray weeds early in spring, before weeds reach 6 inches in height or 4 inch diameter rosettes. Treatments – Authority First 3.2 oz + Rage D-Tech 12-16 oz/A + COC. Add glyphosate if grasses are emerged or as an additional mode-of-action for marestail and other broadleaf weeds.
