What if cantaloupe dies?

The leaves appear pale yellow or even dark brown concentric wheel-shaped depression, which causes cracks for a short time. The stem is soaked first, and always secretes reddish-brown fat, and finally becomes a gray-brown cork-like dry diseased spot with small black spots (capsule shell) on it. Disease spots often occur at the root head or stem node, and the root head often expands to make the whole plant wither and die (commonly known as head failure).

Control method: spraying mankuning 800 times solution. Once every 5 ~ 7 days, 4 ~ 5 times in a row.

Use 10 times water of Wankunning or 53.8% copper hydroxide to smear the diseased part of stem, once every 5-7 days when the disease occurs.
