Learn about the main types of pests and diseases of peanuts and their proper period of occurrence so as to help early prevention and treatment.
The main pests:
1, underground pests. The main pests are earthworms, ground tigers, cockroaches, and golden needles, which are the main low-level pests that affect peanut germination, fruit setting, scab, and yield. They are harmful to the entire growth and development period, especially in the sticky soil.
2, locusts. The hazard period is from May to June (the seedling stage) and from July to August (mid-and late growth period), and the seedling stage is the main damage. In the high-temperature and drought climate conditions, serious damage often occurs.
3, red spider. The period of damage is June-August, and drought often occurs in drought years.
4, cotton bollworm. The period from June to August is mainly the third and fourth generations of cotton bollworms, especially in drought years.
Major diseases:
1, root rot. Peanut root rot, commonly known as "rat tail" and "root rot", is a fungal disease in peanut blight. The harm is relatively serious, especially when the seed is exposed to rain, or the mass of land that has been replanted, occurs quite. serious.
2, peanut virus disease. Peanut virus diseases include peanut stripe virus disease, peanut yellow mosaic virus disease, peanut dwarf virus disease, and peanut bud disease virus disease, among which the most widespread are streak virus diseases.
