Currently, the herbicides registered in China for napa cabbage include 33% pendimethalin emulsifiable concentrate (100-150 ml per mu), applied as a soil treatment after sowing but before emergence, or before transplanting the cabbage; it can control some grasses and broadleaf weeds. If using pendimethalin over a large area, it is advisable to test on a small area first. For soil treatment, you can also try 50% napropamide wettable powder (100-120 g per mu). There is no post-emergence herbicide for broadleaf weeds in cabbage, only 5% quizalofop-p-ethyl emulsifiable concentrate for grass weeds. In addition, before planting cabbage, you can irrigate first to force weeds to sprout, then use paraquat or glyphosate to kill them.
