What caused the death of zucchini?

What caused the death of zucchini? How to prevent and cure it? The cause of zucchini death is likely to be vine blight, mainly harmful to leaves and stems, followed by melon strips. The leaves are killed, resulting in nearly round or irregular disease spots, and sometimes the disease spots show a "V" shape or semicircle from the leaf edge to the inside, which is light brown to yellowish brown. In the later stage, the disease spot is easy to break, and the wheel pattern of the disease spot is not obvious, and there are many small black spots on the disease spot. Stem damage, mostly occurred in or near the node, began to appear oil stains, oval or fusiform, slightly sunken, gray to dark brown, secreting amber glue substance. After drying, it is reddish brown, the disease part shrinks longitudinally, and a large number of small black spots are scattered on the surface, which can cause stem rot when it is serious. The melon strips were killed and the flesh was light brown. Prevention and treatment: at the initial stage of the disease, 70% methyl topiramate wettable powder can be sprayed 500 times 600 times, or 40% nova EC 10000 times, once every 4 to 5 days, 3 times in a row.
