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, which have single functions, only have disease prevention effects, and the use technology is complicated, which is not safe for crops; they can effectively control Subterranean pest products such as phorate and methylthion are highly toxic

Embodiment 1

[0027] Example 1: 3% spirotetramat boscalid suspension seed coating

[0028]

[0029] According to the above formula, in a dispersion tank equipped with a high-speed stirrer, disperse the original drug and additives in water, and coarsely pulverize the original drug; the coarsely pulverized mixture is continuously sent into the pulverizer with a quantitative pump, Carry out fine pulverization; the material separated from the medium and discharged is sent to the final mixing tank, and the xanthan gum solution prepared in addition is added to the mixing tank, and mixed evenly with the pulverized material to obtain 3% spirotetramat. Amine suspension seed coating.

[0030] The coating method of the suspension seed coating agent:

[0031] Use a coating machine or artificial method to mix the corn seeds with the seed coating agent at a ratio of 300g / 100KG corn seeds so that the surface of the seeds is evenly coated with the suspended seed coating agent.

Embodiment 2

[0032] Example 2: 22% spirotetramat boscalid suspension seed coating

[0033]

[0034]

[0035] The preparation method is the same as in Example 1.

Embodiment 3

[0036] Example 3: 31% spirotetramat Boscalid suspension seed coating

[0037]

[0038] The preparation method is the same as in Example 1.

Abstract

The invention discloses a suspension seed coating agent containing spirotetramat. The suspension seed coating agent is prepared from the following components in percentage by weight: 2-30% of spirotetramat, 1-20% of boscalid, 1-8% of wetting dispersant, 1-10% of film forming agent, 1-10% of colorant, 0.1-2% of thickener, 1-5% of antifreezing agent, 0.1-1% of preservative, 0.1-1% of defoaming agentand distilled water being supplemented gradually to reach 100%. The suspension seed coating agent is low in toxicity, good in medical effect, long in persistent effect, high in working efficiency andeconomical and safe, can reduce the dosage of the effective components of pesticide, reduce the environmental pollution, improve the utilization rate of the pesticide, and is convenient to use. Seedscan be treated through mechanical stirring or manual operation, and requirements of different users can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparations, in particular to a suspension seed coating containing spirotetramat and boscalid and a preparation method thereof. Background technique [0002] In modern agricultural production, seed 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 treatment technology developed on the basis of traditional seed soaking or seed dressing technology. Seeds in dry or wet state are coated with a binder-containing pesticide or fertilizer composition to form a protective layer with certain functions and coating strength on the outside of the seeds. This process is called seed coating. The combined substance wrapped on the outside of the seeds is called a seed coating agent, which is a pesticide preparation with film-forming properties used for cr...
