Common Pests and Control Methods of落地生根
As a star variety among succulent plants, 落地生根 is favored by gardening enthusiasts for its unique propagation methods and ornamental value. However, pest problems often become the biggest threat to its healthy growth during maintenance. This article will systematically analyze the characteristics of three typical pests and provide scientific control solutions to help you create healthy plants.
Characteristics and Control Strategies of Aphid Infestation
Pest Identification and Harm Analysis
Aphids often gather on new leaves and buds, absorbing plant sap through their piercing-sucking mouthparts, leading to curled and deformed leaves. The honeydew they secrete can easily cause sooty mold, resulting in dual damage.
Four-Step Ecological Control Method
1. Orange Peel Ferment Liquid: Soak fresh orange peels for 48 hours, then dilute 1:50 and spray. 2. Chili Garlic Water: Boil dried chili and garlic, filter the liquid, and spray in the morning. 3. Yellow Board Trapping: Hang yellow sticky pest boards around the plants. 4. Biological Control: Introduce natural enemies like ladybugs to establish ecological balance.
Key Points for the Control of Scale Insects
Control of Insect Development Cycle
The best control period is the nymph stage (1-3 instars), when the waxy layer is not fully formed, and the drug penetration rate is increased by 40%. It is recommended to check the back of leaves and stem joints weekly.
Scientific Drug Application Schedule
• Early Spring: Prevent with 40% omethoate emulsion 1500 times liquid. • Outbreak Period: 25% thiazine suspension + organic silicone additive. • Winter: Use lime sulfur mixture to clear the garden and kill overwintering eggs.
Comprehensive Control of Comma Butterfly Larvae
Construction of Physical Barrier System
Use a 60-mesh anti-insect net to create a three-dimensional protection, paying special attention to the sealing of the net frame at the junction with the potting soil. Combine with regular manual inspections and promptly remove egg masses.
Application Scheme of Biological Agents
Apply Bacillus thuringiensis (BT preparation) 200 times liquid on the leaf surface, combined with the nuclear polyhedrosis virus preparation of the diamondback moth, to achieve green control.
Establish a preventive maintenance system: Apply 3% furan丹 granules (5-8g per pot) monthly, combined with matrix high-temperature disinfection (exposure to the sun for 3 days in summer). By controlling temperature and humidity (keeping the environmental humidity below 60%) and combining reasonable plant spacing, it can reduce the incidence of pests by 85%. Regularly rotating the drug application mechanism can effectively delay the development of pest resistance.
