Wheat can't yield high without seed dressing

Why dressing wheat seeds

Dressing wheat seeds is mainly to reduce the losses caused by wheat diseases and insect pests and achieve high yields.

Common wheat diseases: sheath blight, root rot, smut, etc. Some of these diseases harm the base of wheat stems and cause malnutrition of wheat plants and the death of wheat seedlings; some harm the ears and affect the formation of grains in the ears .

Common wheat pests: mainly mole crickets, golden needle insects, grubs, etc., which will cause the lack of seedlings and ridges at the seedling stage of wheat, forming weak seedlings, resulting in the failure of normal growth and filling of wheat, which affects wheat tillers and reduces crop production.

Wheat seed dressing agents are generally compounded with fungicides, which can inhibit the infection of germs and reduce the occurrence of diseases, thereby achieving an increase in yield.

What seed dressing agent is needed

To prevent root rot, sheath blight and other diseases, thiamethoxam, fludioxonil and difenoconazole can be used.

For the prevention and treatment of total erosion, silthiozamide can be used, and the effect will be better.

For the prevention and control of pests such as gold needles, grubs, worms, etc., phoxim, imidacloprid, and thiamethoxam can be used, and thiamethoxam is recommended, which is relatively safe.

Seed dressing time should be 7~15 days before sowing, and the seeds must be aired before dressing, so that ultraviolet rays can kill some harmful bacteria. After the seeds are mixed, they should be air-dried naturally in a cool place instead of being exposed to the sun to prevent the seeds from phytotoxicity.

Seed coating agent ≠ seed dressing agent

Generally speaking, there are three kinds of seed treatment agents: seed soaking agent, seed dressing agent, and seed coating agent. But in actual application, people usually call them "seed dressing agent". Although they are used as seed treatment, but seed coating agent ≠ seed dressing agent.

The common point of seed dressing and seed soaking agents is that before sowing, farmers use solid pesticides or use aqueous solutions containing pesticides to treat seeds according to the needs of prevention and control. It is a method of field application, and seed coatings are dressings. An upgraded version of the seed agent.
