What Pests Does a Fire Dragon Plant Have
As a star variety in the succulent plant world, the Fire Dragon plant is deeply loved by gardening enthusiasts for its unique shape and fleshy leaves. However, during its growth process, pest issues are always a key concern for caretakers. This article will systematically analyze the three common pest types of Fire Dragon plants and provide practical prevention and control solutions to help you create a healthy and beautiful potted Fire Dragon.
Complete Guide to Preventing and Treating Three Major Pests of Fire Dragon Plants
Whitefly Infestation: The Hidden Killer of Leaf Health
Whiteflies are one of the most common pests of Fire Dragon plants, with these 1-2 mm long white flying insects often gathering on the backs of leaves to suck sap. Initially, the leaves develop yellow spots, and in severe cases, they can curl and fall off. It is recommended to use a 40% omethoate emulsion 1000 times solution for spraying, combined with physical removal once a week (using a cotton swab dipped in alcohol). Special note: After spraying, ensure proper ventilation to avoid residual damage.
Scale Insect Analysis: Identification and Eradication Solutions
Including six subspecies such as shield scale insects and citrus mealybugs, their secretions can cause sooty mold. The key prevention period is in spring and autumn, and you can use a 40% fast-acting emulsion 1500 times solution for continuous spraying three times (with a 5-day interval). For root mealybugs, it is recommended to use the pot immersion method: immerse the entire plant in a 0.1% matrine solution at 40℃ for 20 minutes to thoroughly kill root pests.
Nematode Control: From Soil Treatment to Plant Rescue
This type of white, thread-like parasite mainly harms the roots and can be prevented by disinfecting the cultivation substrate with high-temperature steam (80℃ for 30 minutes). Infected plants need to be treated immediately by pruning the roots: retain the healthy stem sections and dip them in carbendazim solution before re-planting. It is recommended to use a 3% carbosulfan granule formulation for soil pretreatment, which provides effective protection for up to 6 months.
By implementing a triple protection system of regular inspections, scientific application of pesticides, and standardized maintenance, the pest resistance of Fire Dragon plants can be significantly improved. It is recommended to use systemic insecticides (such as imidacloprid) for preventive treatment monthly, combined with the application of phosphorus-potassium fertilizers to enhance the plant's own resistance, allowing your Fire Dragon plant to stay free from pest troubles and display its best ornamental state.
