Comprehensive control 1. Keep the plant healthy: Strengthen daily maintenance and improve the disease resistance of multiflora plants. 2. Detect and deal with in time: Regularly inspect multiflora plants and take timely measures when soot blight and scale insects are found. 3. Reasonably match control methods: According to the actual situation, reasonably match physical, biological, and chemical control methods to achieve the best control effect.
