The newly knotted cantaloupe began to turn black and then rot.

Young melons that harm flowers are most common. At the early stage of the disease, the buds and pedicels of young melons were soaked in water, and the color gradually faded, and the diseased parts became soft and rotten. When wet, the surface of the lesion is densely covered with gray-black mold. Corolla withered and rotted, melon branches stopped growing, and melon tips rotted.

Prevention and control methods:

First of all, we should control the temperature and humidity in the greenhouse and create an ecological environment with high temperature and low humidity to control the occurrence and development of gray mold.

? Second, pay attention to crop rotation, increase the application of organic fertilizer, rationally fertilize water, adjust the relationship between balanced nutritional growth and reproductive growth, and promote the health of melon seedlings.
