Have a preventive effect. (2) after the onset with thiophanate-methyl, carbendazim, 400 times IRRIGATING Epu Long pesticide, 8-10 days filling time, controlled spreading effect. The diseased plants should be removed in time, and the above drugs should be used for disinfection in the acupoints to control soil transmission.
Cucumber wilt disease agricultural control: (1) Selection of resistant varieties, such as Changchun Mia, Jinza 2, 3, 4 and Zhongnong 5, etc. (2) Seed disinfection, seed coating or 55 ° C warm water soaking for 15 minutes disinfection. (3) Adopting germination live broadcast. After the seed is germinated, the seedling is broadcasted in the nursery, and the seedling transplanting is not carried out twice, and the root is not damaged. (4) Rotation. For more than 5 years of rotation with non-melon crops, the seedbed should be exchanged or replaced with new soil after 2-3 years. (5) Improve cultivation management.
