Disease and Control Methods of Fózuolián
Fózuolián, as a star variety among succulent plants, is deeply loved by horticulture enthusiasts for its unique lotus seat shape. However, in the actual maintenance process, fungal infections and environmental factors often lead to plant diseases. This article systematically sorts out the key points of prevention and control through the analysis of 4 typical disease illustrations.
Control Plan for Fózuolián Fusarium Disease
Symptom Identification and Transmission Characteristics
Bacterial Fusarium disease quickly invades through root wounds, causing brown spots on the rootstock at the early stage of infection, which can lead to the entire plant rotting within 48 hours. This bacterium can survive in moist soil for up to 6 months, so it is necessary to pay special attention to pot changing and disinfection.
Three-step Prevention and Treatment Method
1. Soak the roots of new plants in 70% thiophanate-methyl 1000 times solution. 2. After drying, apply sulfur powder to form a protective layer. 3. Replace the breathable matrix containing perlite every spring.
Strategy for Dealing with Fózuolián (T-J) Disease
Typical Disease Evolution Process
Fungal (T-J) disease is most prevalent during the plum rain season, with initial leaf spots appearing as brown pinpoint spots, which expand to circular spots 3-5mm in diameter within 7 days. Excessive application of nitrogenous fertilizer can accelerate the reproduction of the pathogen, causing plant dehydration and withering.
Environmental Control and Fungicide Selection
• Maintain 50% shade net coverage. • Install a circulating fan to maintain air circulation. • Alternate between spraying methyl thiophanate and (T-J) fomesafen dual-effect fungicides.
Comprehensive Control of Fózuolián Rust Disease
Symptom Feature Identification
The epidermis of the stem shows raised rust-colored plaques, spreading upwards along the vascular bundles. This disease has a distinct seasonality, with an incidence rate in spring and autumn three times higher than in summer, requiring key monitoring.
Precise Fungicide Application Plan
At the early stage of the disease, apply 12.5% diniconazole 3000 times solution to the stem base, twice a week for 3 consecutive weeks. When pruning diseased branches, wipe the tools with alcohol cotton to avoid cross-infection.
Prevention of Physiological Diseases in Fózuolián
Environmental Abnormal Symptoms
Strong light causes leaf margin scorching (sunburn disease), lack of light leads to stem internode elongation (yellowing syndrome), and low temperature causes damage to the growth point (dormancy phenomenon). It is recommended to configure a temperature and humidity meter for real-time monitoring, maintaining an ideal range of 15-28°C.
Intelligent Maintenance Suggestions
• Install intelligent grow lights (6 hours daily). • Use ceramsite mulch to adjust the matrix moisture. • Apply phosphorus and potassium fertilizers monthly in spring and autumn to enhance resistance.
Through systematic disease prevention and scientific maintenance, Fózuolián can maintain a 5-8 year ornamental cycle. It is recommended to establish a maintenance log to record temperature and humidity changes and fertilization cycles, use biological control to replace chemical agents, and achieve ecological health management.
