supplying the northern United States ( USDA, 2017b ). In Florida, cabbage is typically grown without a plastic mulch and as a result, weeds are a significant problem in most fields. Weed competition may reduce cabbage growth, quality, and yield by competing

summer weeds can be problematic in fallow fields. Cover cropping can provide effective weed control, but the practice must be simple to implement. In the northeastern United States, there are few options available fitting the requirement for a rapid

Crop tolerance (CT) to weed interference is the ability of the crop to endure or avoid competitive stress from weeds without substantial reduction in growth or yield. Historically, CT has been a fundamental component of weed management, although the
