(2) rotation, select sandy soil, and pay attention not to continuous cropping with Solanaceae vegetables or cotton. Eggplant and onion and garlic rotation is the best, and the rotation period is 3-4 years, especially with food crops, especially rice.

(3) to cultivate strong seedlings and improve the planting quality of eggplant. Use red eggplant and other rootstocks to graft, use nutrition bowl to raise seedlings, transplant with soil when planting, and pay attention to prevent or reduce eggplant root injury in the agricultural operations such as seedling division, pseudo-planting, planting, weeding and so on.

(4) after planting, watering in sunny and high temperature, reasonable irrigation, increasing rotten organic fertilizer, hoeing as early as possible, keeping soil moisture, increasing soil temperature and reducing the harm of Verticillium wilt.

Plastic film cover eggplant, increase the ground temperature, the disease prevention effect is obvious.

II. Chemical control of Verticillium wilt of eggplant

(2) after planting slow seedlings, eggplant was irrigated with 50% thiophanate wettable powder 400 times, or 50% carbendazim wettable powder 500 times, or 50% carbendazim wettable powder 500 times + 50% carbendazim wettable powder 800 times. Each eggplant was irrigated with 0.3 kg of medicine solution once every 7 days and 3 times continuously.

(3) 50% carbendazim wettable powder 1000 times, 50% carbendazim wettable powder 1000 times, 5% carbendazim 400 times or 15% carbendazim 1000 times can be irrigated to the root, each plant 200ml, once every 10 days, alternately irrigated for 2 times or 3 times.

Eggplant Verticillium wilt in the seedling stage is less, generally in the door eggplant fruit after the disease, so, at this stage should pay attention to whether infected with the disease.
