What should be used to control pumpkin pests and diseases? Please give an introductionPumpkins have quite a few pests and diseases. Below are several common control methods for pumpkin pests and diseases for reference:
The main diseases of pumpkin are viral disease and powdery mildew. Viral disease is also called mosaic disease. After the plant is infected, the leaves become mosaic-like, wrinkled and smaller, and dark green tumor-like raised spots appear; the fruit becomes deformed, and the plant is obviously stunted and dwarfed. A relatively effective measure for controlling the virus is to control and eliminate aphids. If diseased plants are found, they should be pulled up and burned as early as possible, and disinfected with lime to prevent spread. Powdery mildew mostly occurs in the middle and late stages of pumpkin growth and can be controlled with triadimefon, carbendazim, colloidal sulfur, and the like.
The main insect pests of pumpkin are aphids and Aulacophora beetles, which can be sprayed and killed with a 600-800 times dilution of 40% dimethoate or a 6000-8000 times dilution of 20% fenvalerate.
