Control of Diseases and insect pests of eggplant in early Spring

Eggplant, which is raised in early spring, mainly controls soil-borne diseases such as quenching, blight and Sclerotinia sclerotiorum. Seedbed soil disinfection, using 50 kg seedbed soil plus 20 g 68% Jinlei water dispersible granules and 10 ml 2.5% suspending agent can be sifted and mixed with a nutrition bowl or laid on the seedling bed. The seedling stage was sprayed with 0.1% potassium dihydrogen phosphate, 0.05% potassium dihydrogen phosphate, 0.05% calcium chloride and so on to improve the disease resistance of the seedlings. After emergence, at the initial stage of the disease, 58% metalaxyl manganese-zinc wettable powder and 64% alum wettable powder were sprayed to control cataplexy, 70% methyl topiramate 800-fold solution to control Rhizoctonia blight, and Sclerotinia sclerotiorum was found. it can be controlled with 1500-fold solution of 50% prohydantoin wettable powder or 1000-fold solution of 50% Nongliling wettable powder. Eggplant cultivated in overwintering can be sprayed with 77% carbendazim 600 times solution, carbendazim and 47% Garinon wettable powder to control bacterial leaf spot. Whether it is overwintering cultivation or early spring seedling cultivation, since January is the lowest temperature of the year, attention should be paid to keeping warm and dehumidifying. In addition, cold resistance should be sprayed with potassium dihydrogen phosphate + brown sugar, 68% Jinlei granule 600 times liquid irrigation, 68.75% easy to protect 600 times liquid spray cold damage.
