See specific product label to determine correct rate for the soil type and weed species found in individual fields. Use herbicides, rotary hoeing, spike-tooth harrowing, cultivation, or a combination of these for weed control. Do not make ridges when cultivating. The ridges will interfere with harvesting. Do not plant soybeans in fields with perennial broadleaf weed problems.
Authority contains the single active ingredient sulfentrazone.
Authority controls certain broadleaves, so tank mix to broaden control spectrum or use within a planned pre followed by post herbicide program. Do not apply Authority if soybeans have emerged, otherwise severe crop injury will result. See label for other restrictions. Command 4E must be incorporated immediately following application on moist soil or within 8 hours on dry soil. Command may drift as spray particles or volatilize off the soil surface and turn off-target vegetation white.
