Product Overview
Authority Supreme herbicide is a powerful pre-emergent tool that attacks weeds before they have a chance to harm your field pea, chickpea, and soybean crop. Its dual modes of action also help manage weed resistance, while providing effective control of a variety of broadleaf and grass weeds during a critical crop development period. Glyphosate and Aim® EC herbicide plus glyphosate can be tank-mixed for added protection.

Application information:
Authority Supreme herbicide is applied at a rate of 10 gallons per acre (100 L/ha) for maximum soil coverage, using medium to coarse droplets. For residual or extended control, apply at 33 or 40 acres per jug based on timing and soil characteristics. Spring showers increase activation potential in the early (pre-plant) season. Post-seed application should be considered in higher disturbance situations. Apply only once per 12-month period.
Rates and packaging: 2 x 8 L jugs per case. Each 8 L jug treats 33 or 40 acres per jug.
Water volume: 10 gal/ac provides best uniform soil coverage with medium to coarse droplet sizes.
Rainfastness: N/A
Tank mixtures: Fill spray tank one-half to two-thirds full with water. With agitator operating, add the recommended amount of ingredients using the WAMLEGS order.
