The melons are sown at seedling stage and seed disinfection is required; after sowing, the melon seedlings are poor in cold resistance, and it is better to use electric heating lines to raise seedlings, and timely remove the knock-out diseased plants caused by freezing, and spray them.

The risk of white rust, and regularly prevent and treat diseases such as sclerotia, downy mildew, virus disease, etc. of the retained strains, increase the seed yield and quality of the retained strains, and reduce the seed colonization rate.
III. Prevention and treatment of special early-ripening cornucopia, anti-season cultivation of eggplant vegetables disease
Special early-ripening and anti-season cultivation of solanaceous fruit crops enters the onset of morbidity. When using Hormones and other hormones, they are mixed with 50% Procymidone (WP) 800 times wettable powder for prevention. Remove residual flowers on the young fruit by hand to reduce the chance of infectious sclerotia and gray mold. At the same time pay attention to insulation and ventilation and dehumidification, regular inspection Solanaceae susceptible to gray mold, leaf mold, sclerotium disease conditions, early prevention and treatment.
