Supporting the main diseases of melon

Melon diseases have long been a major concern for farmers, significantly impacting both the quality and yield of the fruit. According to **China Pesticide Network**, here are some effective strategies to manage common melon diseases. **1. Mosaic Disease Symptoms:** In the early stages, infected leaves show yellow-green and dark green mottling. The leaves become smaller, curled, and uneven in shape. Vines may twist and shrink, leading to stunted growth and small fruits with mottled or slightly raised spots on the surface. **Control Measures:** - Practice good cultivation and disease prevention by controlling pests like aphids. - Soak seeds in 55°C warm water for 20 minutes, then cool them in cold water before germination and sowing. - Grow strong seedlings and plant them at proper spacing to avoid contact during pruning or pollination. - Implement balanced fertilization to boost plant resistance. - If aphids are detected, spray 20% virus A wettable powder diluted 500 times. **2. Leaf Blight Symptoms:** This disease primarily affects the leaves. Early signs include brown spots that gradually expand, forming large, irregular lesions. The edges may appear water-soaked, and the affected areas can merge, causing the leaves to dry out. Fruits may also show similar symptoms, with bacterial infection leading to rot. **Pesticide Control Methods:** - Use disease-free seeds, and treat them with 0.3% 75% chlorothalonil wettable powder or 50% chlorhexidine wettable powder. - Rotate crops and avoid planting cucurbits consecutively. - Improve soil fertility with organic manure and manage irrigation to prevent waterlogging. Remove diseased leaves promptly. - Spray 75% chlorothalonil WP at 600 times dilution, or 50% phlegm WP at 1500 times, every 7–10 days for 2–3 applications. **3. Anthracnose Symptoms:** Seedlings may develop water-soaked lesions near the ground. On leaves, the lesions are round, yellow-brown or red-brown with a yellow halo. Stems and petioles show elongated, sunken spots. Infected fruits crack open, and under high humidity, pink, sticky fluid oozes from the lesions. **Control Measures:** - Rotate crops with non-melon plants for at least three years. - Use 75% chlorothalonil WP diluted 800 times or 50% thiophanate-methyl WP at 800 times as recommended by **Pesticide Network**. By implementing these preventive and control measures, farmers can effectively reduce the impact of melon diseases and improve overall crop health and productivity.
