This article provides a systematic prevention and treatment plan for common diseases and pests of滴水观音, helping growers build a complete plant protection system.
滴水观音 Disease Prevention and Treatment System
Key Points for Leaf Spot Disease Prevention and Treatment
Leaf spot disease is often caused by excessive humidity, initially manifested as brown spots on the leaf edges. It is recommended to adopt a three-level prevention and treatment: 1. Improve the ventilation environment; 2. Regularly spray carbendazim 800 times liquid; 3. Spray carbendazim every week during the outbreak period, for 3 consecutive times. Special reminder: Keep the leaf surface dry in winter and avoid spraying water at night.
(T-J) Disease Comprehensive Control
(T-J) disease is highly contagious and requires the use of 75% thiophanate-methyl 500 times liquid for three-dimensional foliar spraying. Focus on the back of the leaves and areas with dense stomata, and use potassium dihydrogen phosphate foliar fertilizer for better results. Prevention needs to be strengthened in spring and autumn, and the potting soil should be disinfected monthly.
