The Diseases and Pests of Xue Zhi Pagoda and Their Control
As a star variety in the succulent world, Xue Zhi Pagoda is deeply loved by flower enthusiasts for its layered pagoda-like shape. However, improper environmental regulation during maintenance often leads to diseases and pests, which can affect the ornamental value or even cause plant death. This article provides an in-depth analysis of three typical diseases and pests and offers scientific control solutions.
Diagnostic Guide for Three Typical Diseases of Xue Zhi Pagoda
Fungal Leaf Spot: A Crisis Caused by Excess Water Accumulation
When the humidity of the maintenance environment is too high, leaves will show brown water-stain-like spots, which are typical features of fungal leaf spot disease. This condition usually occurs during the seasonal transition between spring and autumn, and special attention should be paid to controlling the watering rhythm, keeping the surface of the substrate dry for 2-3 days before re-watering.
Scale Insects: Persistent Juice Plunderers
This type of white waxy pest often gathers in the axils of leaves, initially visible as scattered white dots, which can cover the entire plant within half a month. The honeydew they secrete can also trigger sooty mold, causing secondary damage.
Black Rot Disease: The Hidden Killer in Summer
In high temperature and humidity conditions, black-brown rot first appears at the base of the stem, which can spread to the entire plant within 48 hours. This disease is highly contagious and requires immediate isolation of the affected plants.
A Three-Stage Stereoscopic Control System
Environmental Regulation: Preventing Trouble Before It Starts
Use a special substrate with 70% particle ratio, combined with red pottery pots to enhance breathability. In summer, set up a shading net to control light intensity and maintain a day-night temperature difference of more than 8°C.
Physical Control: Rapid Emergency Response
Immediately use 75% alcohol cotton swabs to kill scale insects upon discovery, cut off the affected leaves in the early stage of leaf spot disease and seal the cut with wood ash. For black rot disease, cut the top for propagation, retaining the healthy top.
Chemical Intervention: Scientific Medication Program
Apply Mancozeb 800x solution for leaf spot disease once a week for three weeks. Use Thiamethoxam 2000x solution for root irrigation during the孵化 period of scale insects, and apply Metalaxyl 3000x solution in the early stage of black rot disease.
By establishing a closed-loop management system of "prevention-monitoring-control," the disease resistance of Xue Zhi Pagoda can be significantly improved. It is recommended to use Bacillus subtilis for biological prevention every month, combined with intelligent humidity monitors for precise maintenance, ensuring that your succulent pagoda remains vibrant forever.
