Main plant protection measures at the seedling stage of cotton
The period from emergence to budding is the seedling period, which lasts for about 40-45 days. In this period, the main pests were seedling and seedling disease. 1. Miao Miao: When the planting rate of cotton plants in the field reaches more than 20%, it should be immediately treated with drugs. Can be used imidacloprid WP 2000 times or 3% acetamiprid WP 3000-4000 times spray control. Control agents should be used interchangeably. 2. Underground pests: Small ground tigers are the main underground pests in cotton seedlings, often causing plant deaths and lack of seedlings. Occurrence of heavier fields can be treated with 40% phoxim EC 500-800 times solution or 1.55 powder 2-3 kg 20 kg compounded soil applied in combination with watering, so that it can be used to treat other earthworms such as earthworms and earthworms. . 3. Cotton seedling diseases: Miao disease is a soil-borne disease, especially in the cotton fields of Liansuo. The soil bacterium original is sufficient. If the air temperature at the seedling stage is low, the environmental conditions of rainy weather are easily invaded by pathogenic bacteria and cause dead seedlings. In the seedling stage, root diseases such as blight, anthracnose, and red rot are common and can cause rotten seed, rotten shoots, root rot, stem rot, etc., as well as cotyledons, true leaves, young shoots, and tender stems.
