What to Do When Succulents Have White Worms
During the care of succulents, if you find white fluffy substances or waxy small insects attached to the leaves, it is likely that they are infested with scale insects. This type of pest not only affects the ornamental value of succulents but can also trigger complications such as sooty mold disease. This article will provide a comprehensive analysis of the response plan for white worms on succulents, from pest identification to systematic control.
Succulent Pest Diagnosis and Control System
One, Chemical Disinfection for Precise Pest Control
For pests that have reached a certain scale, it is recommended to use a 40% carbaryl emulsion diluted 1500 times for foliar application. Three points need to be noted during operation: applying the pesticide in the early morning or evening to avoid burning, focusing on the back of the leaves where eggs gather, and using the pesticide continuously with a 7-day interval. After the application, the succulents should be moved to a well-ventilated area to prevent residual pesticide from causing secondary damage.
Two, Threefold Physical Control Strategies
1. Local Pruning Method: For plants with less than 30% pest damage, use a sanitized scissor to make an oblique cut 2mm from the leaf edge and apply carbendazim powder to the cut. 2. High-Pressure Washing Method: Choose to wash the leaves with a pressure sprayer at a 45° angle when the temperature is above 25°C at noon, controlling the water flow intensity to less than 0.3MPa. 3. Tobacco Ash Solution: Mix 20g of tobacco ash with 500ml of warm water, let it sit for 24 hours, filter it, and add 3 drops of dishwashing liquid to enhance adhesion.
Succulent Care Prevention System
Three, Key Points of Environmental Regulation
Choose breathable containers like red pottery, and use a soil mixture in a 3:2:1 ratio (akadama soil: vermiculite: coconut bran), and disinfect at high temperature in the microwave for 5 minutes. Wipe the pot edges with 75% alcohol wipes monthly and regularly check for eggs in the leaf axils. Maintain the environmental humidity between 40-60%, and place them with a 10cm spacing to enhance ventilation.
Four, New Trends in Biological Control
Introduce natural predators such as ladybugs for ecological control, releasing 2-3 adult insects per square meter. Combine planting with pest-repelling plants such as mint and rosemary to form a natural protective barrier. It is recommended to apply neem extract biological preparations once each in spring and autumn to establish a long-term protective mechanism.
Through a three-phase management system of 'early prevention + mid-term control + late-stage maintenance,' the incidence of pests can be effectively reduced by over 85%. Regularly observe the plant's condition, take timely measures when pests are found, and配合 scientific care environment to keep succulents always in a healthy growing state.
