• Preen Lawn Crabgrass Control can be applied with a drop or rotary spreader designed to apply granular fertilizers. For best results, apply this product evenly and uniformly over the turfgrass area, avoiding streaking, skips or overlaps.
• To optimize product performance apply this product within a few days after mowing and delay mowing again for a few days after the application. Most effective weed control will be obtained when Preen Lawn Crabgrass Control is activated by rainfall or irrigation. Performance is improved if application is followed by 1/2" of rainfall or irrigation. Erratic weed control may result if not activated by rainfall or irrigation within 30 days after application.
• Preen Lawn Crabgrass Control should be applied in the spring or fall prior to weed seed germination for control of weeds in established yards.
