Pest and Disease Control Techniques and Methods for Greenhouse Watermelon
This article introduces the relevant aspects of pest and disease control techniques and methods for greenhouse watermelon. Next, the editor will introduce to everyone.
Pest and Disease Control Techniques and Methods for Greenhouse Watermelon
When planting greenhouse watermelon, it is necessary to use soil that has not been planted with other crops and disinfect with carbendazim. When the soil moisture is high, apply plant ash to reduce the water content. When the disease occurs, it is necessary to spray the medicine in time for treatment. After seedlings emerge, you can use mancozeb and thiophanate-methyl.
Common Diseases in Greenhouse Watermelon Planting
1. Damping-off: This disease mainly occurs on the stems and stem bases of watermelon, showing brown, water-soaked lesions. The leaves will not wilt, and the disease progresses quickly in low temperature and high humidity environments. Seedlings can die within 2-3 days after infection.
2. Root Rot: This disease mainly occurs on the tip of the watermelon root, showing brown lesions that gradually rot, and the leaves will also wilt. The disease is more likely to occur in low temperature and high humidity environments.
3. Bakanae Disease: Similar to damping-off, this disease occurs on the stems and stem bases of watermelon, showing water-soaked, brown sunken lesions. The leaves of watermelon wilt, and the disease is more likely to occur in high temperature and high humidity environments.
4. Root Rot Disease: This disease mainly occurs on the tip of the watermelon root and severely affects the growth and development of the plant, especially the root part. It is more likely to occur in high temperature and humid environments.
Major Pests in Greenhouse Watermelon Cultivation
The most common pest when planting greenhouse watermelon is nematodes, which usually occur simultaneously with fungal diseases, such as the common wilt disease. After the disease occurs, it causes wounds in the plant roots, and then a large number of pathogens will infect through the wounds, leading to worsening of the disease.
