How to prevent and control pests and diseases in early spring eggplant? Key technical points to master
For eggplant seedlings raised in early spring, the main focus is preventing and controlling soil-borne diseases: damping-off, rhizoctonia rot and sclerotinia rot. For seedbed soil disinfection, mix 50 kg of seedbed soil with 20 g of 68% Jinlei water-dispersible granules and 10 ml of 2.5% Shileshi suspension concentrate, sift the soil and mix well, then fill nutrient pots, or spread it over the seedling bed. During the seedling stage, spray 0.1%-0.2% monopotassium phosphate...

For seedbed soil disinfection, mix 50 kg of seedbed soil with 20 g of 68% Jinlei water-dispersible granules and 10 ml of 2.5% Shileshi suspension concentrate, sift the soil and mix well, then fill nutrient pots, 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 500x solution or 64% Sandofan wettable powder 500x solution to control damping-off; drench with 70% thiophanate-methyl 800x solution to control rhizoctonia rot; if sclerotinia rot is found, use 50% iprodione wettable powder 1500x solution, or 50% vinclozolin wettable powder 1000x solution for control.
For eggplant grown over winter, to control bacterial leaf spot, spray 77% Kocide wettable powder 600x solution, Xijunling, or 47% Kasumin wettable powder.
Whether grown over winter or raised as early spring seedlings, 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 for cold resistance, drench with 68% Jinlei granules 600x solution, and spray 68.75% Yibao 600x solution to prevent cold damage.
