How to carry out chemical seed dressing
For uncoated cotton seeds, the use of chemical seed dressing is an effective measure to prevent underground pests and seedling diseases and improve the seedling rate. There are many types of chemicals that can be used for seed dressing, including the bacteriostatic agents carbendazim, seed dressing double, etc., and the insecticides include carbofuran, etc. In order to improve the control effect, some compound seed dressing agents have emerged in recent years. Many compound seed dressing agents have been commercialized, which can prevent diseases and control insects, and can be purchased according to needs.
The dosage of chemical seed dressing is generally 0.5% to 1% of the dry weight of the seeds. However, the dosage of different products varies greatly, so the dosage must be determined according to the product instructions. If seeds are soaked before sowing, the soaked cotton seeds should be drained and air-conditioned until the linters turn white, and then the seeds should be dressed; if dry seeds (maozi or wanzi) are used for sowing, the surface of the seeds can be sprayed first, and then the seeds can be dressed; If the seeds are soaked to induce germination, then chemical seed dressing should be carried out before sowing. Whether wet seeds or dry seeds are used for seed dressing, it is best to sow seeds immediately after seed dressing. Do not leave them for a long time to avoid reducing seed vitality and efficacy, or causing the risk of accidental poisoning of humans and animals.
