Wheat seed dressing is a rigid medicine, what are the precautions?

Wheat seed dressing

The use of wheat seed dressing can improve the emergence of wheat seeds and the growth of seedlings, and have a good preventive effect on wheat soil-borne diseases (sheath blight, total erosion, root rot, stem base rot, etc.) and insect pests (grubs, mole crickets, needleworms, aphids, etc.), which can play a role in strengthening roots and seedlings, and lay the foundation for the stable and high yield of wheat in the second year.

Determine the type of medication to take

First of all, according to the local pest and disease situation to choose a good type of medicine, if the local environment in the seedling stage of the insect pest is light, but the disease is extremely important, then the seed dressing only needs fungicide, no need to add insecticides; On the contrary, only pesticides are added, no fungicides are added. But if it is the phenomenon of mixed occurrence of pests and diseases, fungicides and fungicides are needed at the same time, if the underground insect pests are more serious, the pesticide dressing can not achieve the expected effect, and the method of combining seed dressing and soil treatment can be used for comprehensive control.

Pay attention to the dosage

The application amount of pesticides is extremely serious during seed dressing, and some farmers blindly increase the dose of pesticides by feeling when dressing seeds, which may have the opposite effect. According to practice, if the amount of pesticides such as powder rust and ocanthal scale is too much during wheat seed dressing, it will cause pesticide damage to the seeds, resulting in delayed emergence of wheat seedlings, slow growth, and in serious cases, there will be a lack of seedlings and dead seedlings. Therefore, we must strictly follow the medication standards to use drugs, and we must not use drugs blindly.

Mix as you go

Generally, after sowing and mixing with seeds, the time is not too long, so as not to reduce the efficacy, generally after mixing seeds with insecticides, after simmering for 2-3 hours, the seeds can be sown after being absorbed by the seeds. After dressing seeds with fungicides, you should understand that sowing or sowing seeds after drying in the shade, if the simmering time is too long or the seeds are not sown for a long time, it is easy to produce pesticide damage.

The purpose of seed dressing should be clear

Seed dressing is only effective for soil-borne or seed-borne diseases, underground pests and some aboveground pests, and some add micro-fertilizer or regulator to supplement soil fertilization, and cannot replace fertilization. As far as wheat is concerned, seed dressing is ineffective or ineffective against rust, powdery mildew, scab, ground tiger, wheat leaf bee, etc., but it can improve resistance.

Pay attention to the situation of the seeds, choose the appropriate drug to use, pay attention to the use of the drug, pay attention to safety issues, and pay attention to the problem of treatment methods.

Be sure to pay attention to the amount of medicine, pay attention to the ratio of water to medicine, the position of spraying on the plant, pay attention to the time of spraying, and the way of spraying.

It is mainly divided into two types, one is a coating agent and the other is a seed dressing agent. The first is made by mixing some microbiotic fertilizers with insecticidal and sterilization, and the second is insecticidal and disease control, but the effect is not as good as the first one.

There are two kinds of commonly used pesticides for wheat seed dressing, namely seed coating agent and seed seed dressing, which can effectively improve the survival rate of wheat, reduce the impact of pests and diseases, and play a very big role in increasing yield and ensuring harvest.

There are herbicides, insecticides, rodenticides, nutrient solutions, and mosquito repellents. And these agents are very effective, and many farmers will buy them.

Total erosion. The disease is a devastating root disease in wheat production, and once total erosion disease occurs, the effect of medication is very small. Seed dressing before sowing is the simplest and most effective measure to prevent total erosion.

Jaundice, powdery mildew, downy mildew, rust can also kill pests. This method is very effective.

There are still many such pests and diseases, such as mole crickets, grubs, needleworms and aphids and other pests and diseases, so we must do a good job of protection in advance and should do a good job of prevention.
