Abstract: In recent years, with the expansion of melon planting area, the frequent and frequent occurrence of diseases and pests has become the primary problem in the planting process. If the prevention and control is improper, it will lead to the outbreak of diseases and pests, resulting in the consequences of yield reduction or even no harvest. Comprehensive use of agricultural control, physical control, chemical control and other measures to control melon diseases and pests can achieve good control effect and provide technical support for melon farmers with high and stable yield.
