Embodiment 1

[0013] Embodiment 1, the best embodiment

[0014] Take emamectin emamectin 0.5%, thiram 10%, carbendazim 10%, wetting and dispersing agent 2.2%, film forming agent 10%, dyeing agent 0.5%, thickener 0.3%, defoamer 0.25%, antifreeze 5%, deionized water 61.25%.

Embodiment 2

[0016] Take emamectin emamectin 0.3%, thiram 5%, carbendazim 5%, wetting and dispersing agent 1.5%, film forming agent 8%, dyeing agent 0.3%, thickener 0.1%, defoamer 0.1%, antifreeze 3%, deionized water 76.7%.

Embodiment 3

[0018] Take emamectin emamectin 10%, thiram 20%, carbendazim 20%, wetting and dispersing agent 4%, film forming agent 20%, dyeing agent 0.9%, thickener 0.5%, defoamer 0.8%, antifreeze 8%, deionized water 15.8%.

[0019] The preparation method of above three embodiments:

[0020] The first step is to prepare a film-forming agent. The film-forming agent is composed of polyvinyl alcohol, β-cyclodextrin and deionized water with a polymerization degree of 2000±50. Polyvinyl alcohol, β-cyclodextrin, deionized water (weight Ratio) = 5:5:90, obtained by the following preparation method, put polyvinyl alcohol, β-cyclodextrin and deionized water in a container, stir and heat to 85-90°C, dissolve slowly, and obtain a transparent viscous liquid , continue to stir at 70-85 ° C;

[0021] In the second step, the three active ingredients of emamectin emamectin, thiram, and carbendazim are jet milled and the wetting and dispersing agent, film-forming agent, dyeing agent, and thickener of the...

Abstract

The invention relates to a suspension seed coating agent for killing insects and preventing diseases, which consists of emamectin benzoate, thiram, carbendazim, wetting and dispersing agent, film forming agent, dyeing agent, thickener, defoaming agent and antifreezing agent and deionized water as raw materials, processed and prepared according to a certain weight ratio. The invention has the advantages of good film-forming property, high suspension rate, uniform coating, fast decomposition, safety and low toxicity, etc., and can be widely used in seed treatment of soybean, corn, rice, wheat and other crops, and can prevent plant underground pests and various Crop nematodes, root rot, scab, bakanae, blight, blight and other diseases, it is easy to use, when processing seeds, it can be either mechanical seed dressing or manual operation, which can meet the needs of different production users .

Description

technical field [0001] The invention relates to the field of pesticide preparations, and specifically discloses a suspension seed coating agent for killing insects and preventing diseases. Background technique [0002] In modern agricultural production, seed chemical treatment is one of the most convenient and economical methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. Seed coating technology is a kind of application developed on the basis of traditional seed soaking or seed dressing technology. The common seed treatment technology is to coat the seeds with a composition such as a pesticide containing a film-forming agent, so that a protective layer with a certain function and coating strength is formed outside the seeds. This process is called seed coating. The combined substance outside is called seed coating agent, which is a kind of pesticide preparation with film-forming properties used for the treatment of crops or other pla...
