Typical Disease Control Solutions for HongfentaiGe
Measures to Deal with Fatal Black Rot Disease
High temperature and humidity in summer can trigger black rot disease. The pathogen invades through wounds or stomata, causing black spots on the stem at the initial stage, which can spread to the entire plant within 24 hours. It is recommended to adopt a three-level defense system:
Preventive stage: Use a breathable substrate with 70% particle ratio and set up a shading net to control the temperature ≤ 32°C.
Initial treatment: Immediately cut off the affected part when black spots are found and apply carbendazim powder to the wound.
Emergency measures: When the whole plant is rotting, keep healthy leaves for leaf insertion and use a mixture of vermiculite and perlite (1:1).
Identification and Treatment of (T-J) Disease
Common in spring and autumn, the leaves show brown sunken spots. Increase the application of phosphorus and potassium fertilizers to enhance resistance and alternately spray mancozeb and benz醚甲环唑 when the disease occurs.
Comprehensive Pest Management for HongfentaiGe
Tips for Controlling Scale Insects
The waxy layer on the surface of the insect's body makes it resistant to pesticides. A combination of physical and chemical treatments is recommended:
Physical removal: Use 75% alcohol cotton swabs for precise spot-killing.
Biological control: Release natural enemies like ladybugs.
Chemical control: Use螺虫乙酯 2000x solution during the nymph stage (May-June) and focus on spraying the back of the leaves.
Key Points for Controlling Root Mealybugs
This pest is隐蔽性强 and often spreads through infested soil. Soak the roots in 40°C water for 15 minutes when repotting and regularly sprinkle diatomaceous earth on the soil surface to form a protective layer.
Key Preventive Maintenance Measures
Establish a quarterly maintenance calendar: Focus on preventing aphids in March-April, strengthen ventilation to prevent black rot in June-September, and control watering to prevent frost damage from November to February of the following year. It is recommended to use smart monitoring equipment that automatically starts a circulation fan when the ambient humidity is persistently >70%.
By implementing this comprehensive protection system, which includes environmental control, biological control, and precise medication, along with a regular inspection system, the incidence of pests and diseases in HongfentaiGe can be significantly reduced. Remember, prevention is better than cure, and good maintenance habits are the fundamental solution.
