Five methods for pest control on succulents
Succulents are loved for their adorable appearance, but the pests hidden in the gaps between leaves and in the soil can be a big headache for caregivers. This article will systematically analyze 5 verified physical and chemical control solutions to help you establish a scientific pest prevention system while protecting the health of your succulents.
Five core pest control solutions for succulents
Forceps physical pest removal method
For scale insect groups with a diameter of over 1mm, it is recommended to manually capture them 2 hours after sunrise. Use a textured forceps at a 45-degree angle along the pest body to accurately grip, combined with weekly spraying of Sophora flavescens alkaloid solution, which can remove 98% of adult insects. After the operation, the plant should be placed in a diffused light environment and observed for 3 days.
Alcohol penetration extermination method
75% medical alcohol achieves penetration and extermination by altering the waxy layer on the insect's epidermis. Use a mist sprayer to evenly spray 20cm away from the plant, focusing on the leaf back and stem junctions. After treatment, ventilation should be strengthened to prevent alcohol residue from causing burns. This method has an 89.7% efficiency against mealybugs (data source: "Gardening Pest and Disease Control" 2023).
Soil ecological reconstruction method
When insect eggs with a diameter less than 0.5mm are found, it is necessary to replace the top 3cm of soil. The new soil should be sterilized at a high temperature of 121°C, with a 1cm thick layer of diatomaceous earth particles on the surface to form a physical barrier. After changing the soil, the application of Bacillus subtilis biological preparations can construct an antibacterial and pest-resistant microecology.
Water immersion asphyxiation control method
Completely immerse the potted plant in warm water at 30°C to kill pests by blocking their respiratory system. Key parameters: The water depth should be 2cm higher than the soil surface, and the soaking time should be strictly controlled between 8-12 minutes. After treatment, use an air pump to force-ventilate the potting soil for 30 minutes to prevent root hypoxia. This method has a 93% efficiency against root mealybugs.
Targeted drug control plan
Use an endosorption agent containing spirotetramat, prepared at a ratio of 1:800. Spray while wearing an N95 mask, focusing on the affected areas. After application, a 72-hour shading treatment is required to prevent photolysis reactions from reducing the efficacy. It is recommended to use yellow boards for monitoring and establish a pest early warning system.
Building a succulent pest prevention system
Use园艺 grade compressed air to clean the leaf gaps monthly and maintain environmental humidity below 60%. Regularly apply plant-derived protectants such as azadirachtin and set food-grade silicone pest control rings around the pot edges. It is recommended to establish a maintenance log to record temperature, humidity, and pest changes for precise control.
