Detailed Explanation of Key Technical Points for Pest and Disease Control in Large-Leaf Privet
Large-leaf privet (Ligustrum lucidum) has strong adaptability and is basically free of pests and diseases; only when its growth is too weak will scale insect damage occur. Control methods: 1. Use a grass bundle or brush to wipe and brush off the overwintering female insects on the trunk and branches and the male pupae inside the cocoons. 2. In May and June, spray for control with 50% malathion 600 times dilution, or 25% imidan 1000-1500 times dilution, or 40% dimethoate emulsifiable concentrate 1000 times dilution, or 10% fenbutatin oxide 400 times dilution.
