How to prevent melon wilt
Fusarium wilt is one of the serious diseases of melons. It is a systemic disease that is invaded by the soil (nutrient solution) and invades the vascular bundles from the roots and rhizomes. The typical symptoms are wilting. Melon growth can occur during the whole growth period, but it is most severe when the vines reach the result stage. After sowing, it can cause rotten seedlings, and the cotyledon or whole-plant wilting occurs at the seedling stage, and the base of the stem becomes brown and shrinking, showing a cataplexy. The incidence of flowering plants up to fruit setting. In this regard, it is necessary to strengthen cultivation and management, adopt comprehensive prevention and control based on crop rotation, selection of disease-resistant varieties, rational irrigation, and supplemented by chemical control. Seeds should be disinfected before sowing. They can be soaked with 40% formaldehyde and 150 times solution for 30 minutes, or with 0.2% to 0.3% of seed weight. It is forbidden to use flood irrigation and string irrigation. A reasonable combination of fertilizers can enhance plant disease resistance. Before the planting, serious disease can be applied to the soil, and the ratio of the soil to the soil is 1:100. The lower part of the hole is covered with a cover and covered with soil. 50% carbendazim or 50% thiophanate-methyl may be used as an agent; in the early stage of disease, when a sporadic diseased plant is found, benzoate, carbendazim, or 500-1000-fold solution of dexamethasone may be used to water the roots of the plant. The strain is administered 200-250 ml, and the interval is 7-10 days. The total irrigation is 2 or 3 times.
