Embodiment 1

[0025] Embodiment 1: preventive effect test

[0026] The test was carried out in the farmland of a farmer in Zhengzhou, Henan Province. Emamectin benzoate and fludioxonil were compounded. The test treatments and application rates are shown in Table 1. For example, treatment 3 is emamectin benzoate It is used in combination with fludioxonil, and the seed coating agent for the test is the compound seed coating agent of emamectin benzoate and fludioxonil, and the application rate is that every 100kg of seeds contains emamectin benzoate Formate original drug 50g, fludioxonil 100g. The control effects of each treatment were counted, and the results are shown in Table 2.

Abstract

The invention relates to the field of pesticide preparation, and discloses a pesticidal disease-prevention suspending seed coating agent. The suspending seed coating agent takes the complex of emamectin benzoate and fludioxonil as the effective ingredients, has the advantages of good film-forming property, uniform coating, high suspending rate, safety low toxicity and the like, and can be widely applied to the seed treatment of crops such as soybean, peanut, cotton, rice, watermelon, rape, wheat, corn and the like. Compared with one of the emamectin benzoate and fludioxonil, the pesticidal disease-prevention effect of the suspending seed coating agent is obviously improved; and meanwhile, the sprouting rate of the seeds is improved. The suspending seed coating agent provided by the invention is convenient for use; and when the suspending seed coating agent is used for treating the seeds, the seeds can be mechanically dressed or manually operated, and the suspending seed coating agent can meet demands of different production groups.

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...
