In the blink of an eye, when the wheat is planted in the autumn season, in order to prevent pests and diseases, in recent years, when the wheat is planted, the seed dressing agent will be selected. Many people are blind when choosing the seed dressing agent. It can be said that I don’t know how to do this at this time. Choosing seed dressing agents, the pesticide network Xiaobian believes that the choice of seed dressing agents must first understand what kind of pests and diseases can be controlled by seed dressing:
First, soil-borne diseases, mainly sheath blight, total erosion, root rot. These bacteria can survive for many years in the soil, and the bacteria can be infested when the seeds begin to germinate after wheat seed dressing.
The second is the system infecting diseases, mainly stalk smut, smut and smut, the pathogens invade the growth point from seed germination, and systematically infect with the growth of wheat plants. The ear stage is a symptom.
The third is underground pests, mainly cockroaches, cockroaches and golden worms. They bite the roots of wheat in the autumn seedling stage and after returning to green, causing lack of seedlings and ridges. An effective method is to dress the pesticide.
After understanding the role of the seed dressing, let's look at how to choose wheat seed dressing:
First, make a coated seed germination test. The germination rate of the seed after coating is the most important part of determining the quality of the seed coating product, and is the means to determine the effect of the coated seed and the unincorporated seed.
The second is the identification of seed dressings. Seed coating agents are well received by farmers' friends because of their good advantages. However, there are many kinds of seed coating agents on the market, and the fish are mixed. This requires people to pay attention to the identification of true and false when buying seed coating agents to prevent being deceived. The specific methods of identification are as follows: (1) The seed coating is too thick, and there is dust falling off after rubbing, which is often a poor quality or fake seed coating agent. (2) The high-quality seed coating agent is a semi-transparent film attached to the surface of the seed, the color is uniform and uniform, and the skin color can be seen through, while the inferior seed coating agent tends to be too dark. (3) The fake seed coating agent has no puncturing and glare. Some fake seed coating agents are prepared by inoculating pesticides with pigments. They have the smell of insecticides and pesticides. The improper operation has a particularly serious effect on the germination rate of seeds.
In this busy autumn season, I hope that every farmer friend can choose a good wheat seed dressing agent.
