The brassica industry has developed an integrated approach to weed control with cultural and herbicide methods used to keep weed populations at low levels such that economic crops can be grown. However, there are no herbicides registered for post-emergence broadleaf weed control in brassica crops, other than at very early post-transplanting. This project aimed at evaluating herbicide options for later post-emergence weed control or strategies using currently registered herbicides to provide effective weed control in Brussels sprouts, cauliflower and broccoli.
