Spodoptera exigua can be controlled by spraying 52.25% of farmland 3000 times or 2.5% of kantrifides 2000 times. Two kinds of pests mixed land can be mixed with the use of the above agents, while adding 72% mancozeb 800 times liquid to prevent fungal diseases such as downy mildew. 3. Note. First, do not eat the cabbage within 7 days after spraying; Second, do not arbitrarily increase the concentration of the drug; Third, the dose should be enough, spray thoroughly sprayed; Fourth, pay attention to inspection after 7-10 days after spraying, as appropriate, re-medication.
