Key points for high-yield cultivation management of summer cultivars
Entering May Day, the early rice enters the stage of weeding and fertilization, and after the work of transplanting the rice, it is a good season for sowing the eggplant in summer. During this period, the eggplant planting is hot and rainy in summer, and the pests and diseases are high.

It should be applied every 10 days, 10 kg of urea per acre, or other fertilizers with the same nitrogen content. At the same time, combined with the prevention and control of pests and diseases, adding 0.3% potassium dihydrogen phosphate and other trace element fertilizers to delay plant senescence and increase the yield in the middle and late stages.
5. Pest control
The common pests and diseases of eggplant include rickets, blight, plague, verticillium, gray mold, red spider, etc. The control measures are as follows:
(1) çŒ ç—… disease, blight: use the fine nail cream Mn-Zn, smog water or methyl thiophanate spray, spray once every 5-7 days, even spray 2-3 times.
(2) Verticillium wilt: the central diseased plant is removed in time; the plants around the central diseased plant are rooted with Bacillus subtilis, preferably once at the time of colonization, and once again when the citrus is expanded.
(3) Cotton blight: spray with azoxystrobin, manganin, manganese zinc, frost urea, manganese zinc, etc., focus on spraying the fruit, spray once every 10 days, for 2-3 times.
(4) Gray mold: use procymidone, cyprodinil, etc., spray once every 5-7 days, 2-3 times in a row. In the time of silk flowering, add procymidone or cyprodinil or fluvox eye, etc., or handle or spray flowers.
