How to Prevent and Control Watermelon Wilt Disease
This article provides an overview of how to prevent and control watermelon wilt disease and shares some small experiences in plant cultivation. Let's find out more.
Watermelon wilt disease causes the leaves and vines to wilt, presenting a dehydrated and dry appearance, but watering or sprinkling cannot solve the fundamental problem. To effectively prevent and control watermelon wilt disease, it is necessary to select wilt-resistant varieties when planting watermelon, treat the soil, and sterilize and disinfect it thoroughly by either sunning and fumigating or using chemicals. Strengthening the growth management of the plants, scientifically raising seedlings, and properly handling seeds before sowing, with the best method being alternating between irrigation and dry farming. Let's delve into the details together.
1. Seed Treatment
Seeds can be soaked in a 40% formaldehyde solution diluted 150 times for about an hour, then rinsed clean, or soaked in warm water at 55°C for 1-2 hours before germination and sowing. Seeds soaked in a 100-fold dilution of Trichoderma viride solution for 2 hours can be sown directly.
2. Scientific Seedling Raising
The soil for raising seedlings can be mixed with well-rotted manure, but soil previously used for growing melons should not be used. The soil can be treated with sunning, fumigation, or sterilized with 50% carbendazim wettable powder. Mix Trichoderma viride with the seedling substrate at a ratio of 1:10, then evenly sprinkle it on the seedbed. When transplanting, immerse the roots of the melon seedlings in a 500-fold dilution of Trichoderma viride solution for about half an hour before planting. Using a 2% Agrochemical 120 aqueous solution diluted 200 times as a root irrigation treatment can effectively prevent the occurrence of watermelon wilt disease.
3. Implementing Crop Rotation
Alternating between irrigation and dry farming can reduce the incidence of the disease. Planting or rotating with Allium crops can reduce the number of pathogens in the soil, effectively mitigating watermelon wilt disease.
4. Root Grafting
Using pumpkin or gourd as the rootstock for grafting can achieve a control effect of over 90% against wilt disease.
5. Chemical Control
Apply a 50% ferbam aqueous solution diluted 500-1000 times or a 50% validamycin wettable powder solution diluted 800 times. Each application should be spaced 7-8 days apart, with a total of 3-5 applications.
The above information provides a comprehensive explanation of how to prevent and control watermelon wilt disease, and detailed methods for preventing and controlling the disease. I hope it can serve as a starting point to solve your green plant problems.
