Complete Solution for Control of Four Major Pests of Echeveria 'Flower Moon'
Scale Insects: A Common Pest in Spring
This type of 2-3mm long, elliptical pest often gathers at the stem nodes, absorbing sap through刺吸式口器. The honeydew they secrete can easily cause sooty mold, leading to dual damage. In early spring, when temperatures rise to 15°C, a mixture of 40% omethoate emulsion and mineral oil can be sprayed on the undersides of leaves to damage their waxy protective layer.
Spider Mites: The Enemy of High Temperature and Dryness
This 0.5mm red mite reproduces by weaving webs on the undersides of leaves, causing dense yellow spots on the affected leaves. It is recommended to use a 30% pyridaben emulsion 2000 times solution with atomized spray every week, maintaining an environmental humidity of over 60%. Special attention should be paid to the web traces at the junction of new and old leaves.
Foreign Invasion: The Crisis of White Spider Mites
Compared to native red spider mites, white spider mites have stronger resistance to pesticides. Their characteristics include a pale body color and rapid movement. For control, alternate the use of 5% spirodiclofen suspension and 22% abamectin·spirodiclofen. Pay attention to drug rotation to avoid resistance and keep the application interval at 7-10 days.
Invisible Killer: Root-Knot Nematodes
This type of soil pest causes tumors in the roots and stem rot. Monthly application of 1.8% abamectin emulsion 1000 times solution can effectively prevent it. Diseased plants need to be repotted immediately, with the original soil treated with high-temperature steam sterilization, and healthy branches can be soaked in carbendazim solution before being re-rooted.
By regularly inspecting hidden areas such as the undersides of leaves and stem bases, combining physical removal with chemical control, the incidence of pests can be significantly reduced. It is recommended to apply slow-release furadan granules every quarter, combined with hanging yellow sticky traps to monitor pest conditions, building a comprehensive protection system.
