January eggplant pest and disease control and management technical points
For eggplants raised as seedlings in early spring, the main focus is controlling soil-borne diseases: damping-off, Rhizoctonia rot and sclerotinia rot. To disinfect the seedbed soil, mix 50 kg of seedbed soil with 20 g of 68% Jinlei water-dispersible granules and 10 ml of 2.5% Shileshi suspension concentrate, sieve and blend the soil, then fill nutrient pots with it, or spread it over the seedling bed. During the seedling stage, spray 0.1%-0.2% monopotassium phosphate, ...
For eggplants raised as seedlings in early spring, the main focus is controlling soil-borne diseases: damping-off, Rhizoctonia rot and sclerotinia rot. To disinfect the seedbed soil, mix 50 kg of seedbed soil with 20 g of 68% Jinlei water-dispersible granules and 10 ml of 2.5% Shileshi suspension concentrate, sieve and blend the soil, then fill nutrient pots with it, or spread it over the seedling bed. During the seedling stage, spray 0.1%-0.2% monopotassium phosphate, 0.05%-0.1% calcium chloride, etc., to improve the disease resistance of the seedlings. After emergence, at the early stage of disease, spray 58% metalaxyl-mancozeb wettable powder at 500 times dilution or 64% Shadufan wettable powder at 500 times dilution to control damping-off; drench with 70% thiophanate-methyl at 800 times dilution to control Rhizoctonia rot; if sclerotinia rot is found, use 50% iprodione wettable powder at 1500 times dilution, or 50% vinclozolin wettable powder at 1000 times dilution for control.
For overwintering eggplant cultivation, to control bacterial leaf spot, spray 77% Keshade wettable powder at 600 times dilution, Xijunling, or 47% Jiaruinong wettable powder.
Whether for overwintering cultivation or early spring seedling raising, since January is the month with the lowest temperatures of the year, attention should be paid to keeping warm and removing moisture. In addition, spray monopotassium phosphate + brown sugar to resist cold, drench with 68% Jinlei granules at 600 times dilution, and spray 68.75% Yibao at 600 times dilution to prevent cold damage.
