Common Pests and Control Methods for Light Bulb Plants
As a star variety among succulents, light bulb plants are deeply favored by gardening enthusiasts for their crystal-clear appearance. However, during the maintenance process, pests such as whiteflies and scale insects often cause the plants to lose their ornamental value. This article systematically analyzes the harmful characteristics and scientific control methods for three typical pests, helping you protect the health of your succulents.
Strategies for Dealing with Whitefly Infestations
Hidden Harm Characteristics
This type of white fly, with a body length of only 1mm, prefers to gather on the back of leaves, causing the plant to wilt by刺吸汁液. The honeydew they secrete can trigger sooty mold, forming black mold spots on the surface of the light bulb, completely eliminating the translucent texture.
Step-by-Step Treatment Plan
At the initial discovery, immediately enhance ventilation and reduce humidity to below 40%. Alternate the use of omethoate (1000 times solution) and malathion (500 times solution), with a 48-hour interval and配合 high-pressure water spray. It is recommended to spray the pesticide twice a week for 3 consecutive weeks, paying attention to rotate 3 or more different insecticides with different mechanisms of action.
Core Technology for Removing Scale Insects
Key Points for Pest Identification
Initially, fluffy attachments appear at the top of the plant, and as the insects secrete more wax, white shields form. Severe infections can lead to vascular bundle blockage, manifesting as overall growth stagnation or even withering.
Physical and Chemical Synergistic Treatment
A small number of insects can be physically removed with 75% alcohol cotton pads. When the pest population erupts, use a quick-acting insecticide (800 times solution) foliar spray combined with root irrigation treatment. It is recommended to apply lime sulfur solution preventively in spring and autumn, which has a significant dissolving effect on the waxy shell.
Comprehensive Control System for Small Black Flies
Pest Occurrence Patterns
Sciarid fly adults prefer humid and humic environments, and their larvae eat the roots, causing wound infections. They have a fast flying and spreading speed, easily causing cross-infection.
Key Points of Environmental Management
Adopt a double-layer protection strategy: cover the surface with 3cm diameter vermiculite to isolate insect eggs, combined with yellow boards for physical adult fly control. Strictly disinfect the growing medium and control watering frequency to keep the soil moisture below 30%. It is recommended to use avermectin granules for preventive soil treatment.
By establishing a full-cycle management system of "prevention, monitoring, and control," the occurrence of succulent plant pests can be effectively controlled. It is recommended to conduct systematic inspections monthly, focusing on hidden areas such as the back of leaves and growth points. Combine biological and chemical controls, maintain a dry and well-ventilated maintenance environment, and allow the light bulb succulents to continuously showcase their crystal beauty.
