Planetary Pest and Disease Control Methods
Key Points for Planetary Pest and Disease Control
As a classic variety of succulents, Astrophytum is deeply loved by gardening enthusiasts for its unique star-shaped ridges. Its pest and disease control requires special attention to temperature and humidity regulation and daily maintenance. The following text will provide a detailed analysis of the characteristics and systematic control methods of three typical pests and diseases.
Fungal Disease Control for Planets
Recognition of Grey Mold Symptoms
In a closed environment with an average daily temperature of 18-23°C and humidity >90%, a water-soaked brown spot appears on the surface of the plant, which forms a gray downy mold layer within 48 hours, and severe cases can lead to the rotting of the ball. Flowering plants are more prone to secondary infections due to pollen scattering.
Development Pattern of Scab Disease
Initially, it presents as an oily spot, and as the pathogen proliferates, it gradually forms a waxy yellow raised granule, eventually evolving into a woody wart with a diameter of 2-3mm, affecting the photosynthetic efficiency of the plant.
Fungal Control Plan
At the early stage of the disease, spray the entire plant with a 70% methyl thiophanate 1000 times solution, supplemented with calcium and magnesium elements to enhance cell wall strength. Every quarter, apply a mixture of benzothiazole and thiamethoxam to the roots, forming a three-dimensional protective system.
Comprehensive Control of Planetary Pests
Characteristics of Red Spider Outbreak
This mite completes one generation every 15 days in a dry environment, piercing the juice of the star body with its mouthparts to form yellow spots, and in severe cases, it can cover the growing point with a web. It can spread to surrounding plants within a 3-meter range through the wind.
Pest Eradication Strategy
Use an alternating spray of 40% omethoate 1500 times solution and pyridaben 2000 times solution, focusing on the back of the leaves and the surface of the potting soil. Combine with hanging yellow sticky traps to monitor changes in pest density.
Planetary Health Maintenance System
Establish a three-level protection mechanism of "prevention-monitoring-control": apply Bacillus subtilis biological agents every month in spring and autumn, set up a rain shelter in summer to control humidity, and maintain a day-night temperature difference of ≤8°C in winter. Regularly rotate the potted plants to ensure uniform light exposure, and new plants need to be isolated and observed for 15 days.
By precisely controlling the soil mixture ratio (particle soil proportion >70%), combined with smart temperature and humidity monitoring equipment, the incidence of pests and diseases can be reduced by 83%. Remember, a healthy growing environment is the best natural protective barrier for planetary plants.
