These five diseases harm different parts of the plant, and the characteristics of the disease are also different. but in the later stage, it will cause grape fruit rot and soft grain phenomenon.

Prevention and control methods: any disease should be treated from the source first, disinfect and sterilize the environment before planting, turn the soil deeply into the sun, and remove all the residual plants in the first year, so as to put an end to the possibility of survival and transmission of pathogens.
