Problems solved by technology

[0004] At present, there are many kinds of seed coating agents promoted and used in China, but most of them have some problems, such as Li Kexiu, Shileshi, and Seed Dressing Shuang, etc. have single functions, only have disease prevention effects, and the use technology is complicated, which is not safe for crops; the application number is The Chinese patent of 98106559.7 discloses a seed coating agent, which has both insecticidal and bactericidal effects, but one of its combinations can only be used for wheat and corn seeds, and the other can only be used for cotton seeds , but cannot be used as a seed coating agent for various crop seeds at the same time, and the application range is narrow

Embodiment 1

[0025] Embodiment 1: preventive effect test

[0026] The test was carried out in the farmland of a farmer in Zhengzhou, Henan Province. Difenoconazole and thiamethoxam were compounded. The test treatments and application rates are shown in Table 1. For example, treatment 3 was used in combination with thiamethoxam and thiamethoxam. The seed coating agent is a compound seed coating agent of thiamethoxam and difenoconazole, and the application rate is 20 g of the original drug of thiamethoxam and 100 g of difenoconazole per 100 kg of seeds. The control effects of each treatment were counted, and the results are shown in Table 2.

Abstract

The invention, relating to the field of pesticide preparation, discloses a flowable concentrate for seed coating for insecticidal purpose and disease prevention. The flowable concentrate for seed coating for insecticidal purpose and disease prevention comprises difenoconazole and thiamethoxam as effective components, has the advantages of good property of film forming, uniform coating, high suspensibility, safety, low toxicity and the like, and can be widely used for the seed treatments of wheat, corn, soybean, peanut, cotton and other plants. Compared with the single use of difenoconazole and thiamethoxam, the flowable concentrate for seed coating has obviously better insecticidal effect and better effect of disease prevention. The flowable concentrate for seed coating can improve the germination capacity of seeds. The flowable concentrate for seed coating is easy to use, when treating seeds, the flowable concentrate for seed coating can be used with mechanical seed dressing or manual operation, satisfying requirements of different production population.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a suspension seed coating agent for killing insects and preventing diseases. Background technique [0002] Subterranean pests refer to a class of pests that live in the soil during the harmful period, mainly including mole crickets, grubs, cutworms and day lilies. There are many kinds of such pests, which harm a wide range of hosts and harm crops such as wheat, corn, sorghum, and cotton. They mainly feed on the seeds, roots, stems, tubers, tubers, seedlings, young leaves and growth points of crops, often resulting in lack of seedlings, broken ridges or poor growth of seedlings, which has a great impact on crop yield. In modern agricultural production, seed pesticide treatment is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. [0003] Seed coating technology is a widely used new seed tr...
