Fusarium wilt is also called wilt disease, which is a fungal soil-borne disease. It is only a melon-like crop. The most serious disease is watermelon and cucumber, followed by melon. Melons can be affected throughout the growth period. The typical symptom of the disease is that the first part of the damaged plant sag is drooping at noon, which seems to be lack of water. It can be restored in the morning or evening, or in the rainy days. Afterwards, the wilting leaves are increasing, the whole plant is wilting, and it can not recover sooner or later, and soon it is dead, cutting the roots. It can be seen that the vascular bundle turns brown. The severity of the disease depends on the amount of pathogens in the soil and environmental conditions. High soil moisture, water accumulation in the roots, high temperature is conducive to disease occurrence. There are more morbid conditions in the climatic conditions after the rain or when the rain is sunny. Large water immersion irrigation, partial application of nitrogen fertilizer, continuous cropping is conducive to the onset. After entering the rainy season, the field is prone to water accumulation, the weather is changeable, the temperature difference is large, and the number of days when the rain is sunny is very favorable for the occurrence of melon wilt. We should seize the fine weather and carry out prevention and control in a timely manner. The control measures are as follows: 1. Agricultural control and non-melon crop rotation, strengthen field cultivation management, increase plant resistance, and find out timely removal of diseased plants. 2. Seed disinfection is carried out after soaking with warm soaking, then soaking with 50% carbendazim WP 100 times for 30~40 minutes, rinse and germination. 3. Before or after the onset of pesticide control, 50% procymidone 1200~1500 times liquid or 50% methyl thiophanate WP 500~600 times liquid, 50% carbendazim WP 500~700 times liquid irrigation Root control, prevention and control once every 7 days, continuous control 2 to 3 times.
