A Detailed Guide to Peanut Seed Dressing Methods and Precautions

Peanut is an important economic crop in China, with an extremely wide planting area, and peanut seed dressing is an important way to achieve high peanut yields. It can not only reduce the occurrence of pests and diseases, but also effectively prevent the phenomenon of dead seedlings and dead plants. At the same time, it can also regulate water quality and promote high yield and good quality. So what seed dressing methods are there for peanuts? What should be noted? Let's take a look together with the editor.

1. Chemical seed dressing

The chemicals used for chemical seed dressing can be selected according to the pests and diseases that commonly occur locally. Generally, chemicals such as thiophanate-methyl, carbendazim, and fenaminosulf can be used. The chemical dosage can be 0.3%-0.5% of the seed weight for seed dressing, which can effectively prevent root rot and dead seedlings. Now, using phoxim emulsifiable concentrate and dimethoate emulsifiable concentrate for seed dressing can effectively control underground pests; using kerosene or diesel at 0.1%-0.2% of the seed weight for seed dressing can effectively prevent underground pests and birds and animals from damaging the seeds and improve the emergence rate.

2. Water-retaining agent seed dressing

Peanut water-retaining agent is a kind of polymer water-absorbing material, a very excellent water-retaining material. It can absorb water hundreds of times its own weight and is suitable for use in dry and poor land, generally increasing yield by about 10%. The method is to moisten the seeds, evenly sprinkle 150-300 grams per mu onto the seeds, and then stir evenly, or carry out coating. The water-retaining agent can also be put into clean water, stirring while adding, so that the water-retaining agent quickly absorbs water and expands until it is mixed into a paste, then pour in the seeds, stir continuously, and after mixing evenly, spread thin to dry for sowing.

3. Seed coating agent seed dressing

Peanut seeds can also be coated with a seed coating agent, which can achieve excellent sterilization and pest control, improve seed vigor, avoid or reduce the impact of unfavorable environments, and also help achieve uniform and strong seedlings and promote early seedling development.

4. Precautions

Try to choose efficient and low-toxicity seed coating agents to ensure safe emergence. When dressing seeds, first pour the chemical into a container, add a small amount of water and stir, then pour in the seed dressing fertilizer, and finally dress the seeds after mixing evenly. When the seed dressing agent can mix the seeds evenly, the less water added the better. Too much water easily causes the seeds to wrinkle and peel. Whether by manual stirring or mechanical stirring, under the premise of mixing the seeds evenly, the shorter the stirring time the better. In addition, after seed dressing, spread them out to dry. Do not let the seeds suffocate and do not expose them to strong sunlight.
