Vegetable Crops

Currently, if a product is available for post-emergence over the top on the intended crop, then it can be used as a postemergence-targeted application with AI driven camera technology. University research is still needed to expand recommendations with new weed control equipment. Follow the equipment manufacturer's advice for effective use.

clomazone (Command 3ME)

Rate 0.5 lb ai/A (21.3 oz/A)

Time Apply to soil before or after seeding but before crop emerges.

Remarks Crop rotation restrictions may be up to 16 months, depending on rate. Sensitive crops include tomatoes and wheat. Some temporary chlorosis of green peas may occur. Avoid overlaps while spraying.

Rate Coarse soils: 1.5 lb ai/A (48 fl oz/A). Medium-texture and fine soils: 2 lb ai/A (64 fl oz/A)

Time Apply after planting and activate with at least 0.5 inch water. If sufficient water will not be available to incorporate the herbicide, incorporate it mechanically before or at planting.

bensulide (Prefar 4-E)

Rate Preemergence: 1.875 lb ai/A (60 fl oz/A); early postemergence: maximum rate is 5.25 fl oz/A at 2- and 4-leaf stage, and 10.6 oz/A at 6- to 8-leaf. Weed control diminishes in fine-texture soils and soils with high organic matter.

Time Apply after planting and activate with at least 0.5 inch water.

clethodim (Select Max, Section Three)
