Poisonous Plant Pest Control
As a popular choice for indoor green plants, the poisonous plant is often affected by pest problems, which can impact its ornamental value. Mastering scientific control methods can not only save the infested plants but also prevent the spread of pests from the source. This article provides systematic solutions for three common pests, along with real-life photographs to help you accurately identify pest characteristics.
Poisonous Plant Leaf Roller Control System
Pest Characteristics and Identification
Curled new leaves in summer and autumn are typical symptoms. The larvae roll the leaves into cylindrical nests, hiding during the day and eating the leaf flesh at night, which can cause the entire plant's leaves to wither and turn brown when severe.
Chemical Control Plan
Use a 40% dimethoate emulsion diluted 1000 times to spray the back of the leaves, once a week for three weeks. Applying the pesticide in the early morning is most effective, and combining it with manually removing the rolled leaves can increase the elimination rate.
Poisonous Plant Aphid Comprehensive Management
Spread wood ash around the tender buds to form a physical barrier, and rinse the leaf surface with a high-pressure water gun weekly. Using neem leaf extract (1:10 dilution with water) can establish a biological protective layer.
Medication Use Specifications
When spraying a 10% imidacloprid solution diluted 2000 times, cover the leaf veins, focusing on the tender shoot areas. After application, avoid direct sunlight for 48 hours to prevent crystallization of the medication that could damage the leaf surface.
Poisonous Plant Scale Insect Eradication Plan
Physical Removal Steps
Gently wipe the pest bodies with alcohol wipes dipped in a soft-bristled brush, and apply 75% medical alcohol locally. For severely infected leaves, it is recommended to prune the entire branch, and the tools should be sterilized at high temperatures to prevent cross-infection.
Alternately use dichlorvos 2000 times solution and spirotetramat suspension, and implement preventive spraying monthly. Strengthening environmental ventilation and maintaining air humidity between 40%-60% can effectively inhibit egg hatching.
Establishing a pest control calendar can significantly improve control results: focusing on preventing aphids in spring, monitoring leaf rollers in summer and autumn, and removing scale insect eggs in winter. It is recommended to combine physical methods such as yellow sticky traps to form a three-dimensional protection system. Regularly applying seaweed acid foliar fertilizer can enhance the plant's resistance to pests, keeping the poisonous plant in the best ornamental condition.
