Weed Control for Broccoli

Cultural Practices

• A number of cultural practices and pre-planting strategies help to control weeds in broccoli through the entire growing season. These include planting in high density, crop rotation, mulching and cover cropping.

Preplanting/Preemergent Herbicides

• Preplanting and preemergent herbicides retard the germination of weed seeds and keep them from emerging. Preplanting herbicides for broccoli include carfentrazone. Metolachlor is a preemergent herbicide and bensulide is both a preplant and preemergent herbicide recommended for broccoli.

Postemergent Herbicides

• Postemergent weed control solutions target already growing weeds and many are available for use with broccoli. These include paraquat, sethoxydim and glyphosate, all sold under a variety of different tradenames.
