Jade Dew Pests and Control Methods
As a star variety in the succulent world, Jade Dew is deeply loved by gardening enthusiasts for its crystal-clear windowed surface. However, stubborn pests like scale insects and root mealybugs pose a serious threat to the health of the plants. This article will systematically analyze the common pest characteristics of Jade Dew and provide scientific control solutions.
Jade Dew Pest Types and Harm Manifestations
Double Harm Characteristics of Scale Insects
This pest, covered with a waxy shell, damages leaf tissue through its piercing-sucking mouthparts. Initially, the leaf surface appears to have sticky honeydew, and later, it leads to the fogging of the windowed surface and the shrinkage of the plant. Their reproduction is significantly aggregated, with a density of up to 300 insects per square centimeter on a single plant.
Concealed Destruction Mode of Root Mealybugs
The white fluffy material surrounding the roots is actually the nest built by root mealybugs. This pest secretes toxins to inhibit the development of capillary roots, causing continuous dehydration of the plant. If not treated in time, the mortality rate can reach up to 70% within three months.
Systematic Control Scheme for Jade Dew Pests
Physical and Mechanical Pest Removal
For early-stage infections, 75% medical alcohol cotton pads can be used to wipe each leaf, combined with a soft-bristle brush to remove insect eggs from the leaf axils. Ensure good ventilation during operation, and avoid direct sunlight for 24 hours after treatment.
Chemical Pest Control System
It is recommended to build a three-layer protection with systemic insecticides: in spring, apply 3% furadan granules (5g/pot), alternate spraying 40% supplet emulsion (1000 times solution) and 25% thiamethoxam water-dispersible granules (2000 times solution) during the growing period, and pay attention to insecticide rotation to prevent resistance.
Ecological Preventive Measures
Apply Bacillus subtilis microbial agent (500 times solution for root irrigation) monthly and lay a layer of diatomite on the medium surface. New plants must undergo a 15-day isolation observation and soak the roots in metalaxyl solution.
Through the above comprehensive control strategies, the incidence of pests can be effectively controlled. It is recommended to conduct systematic inspections every quarter, especially focusing on hidden areas such as the back of leaves and the root neck. Remember, investing 1 part of effort in prevention is better than spending 10 parts in treatment.
