Simazine water dispersant granule and preparation method thereof

Abstract

The invention discloses a simazine water dispersant granule and a preparation method thereof. The simazine water dispersant granule comprises the following components: 3-30 percent of simazine, 3-12 percent of dispersant, 3-10 percent of wetting agent, 5-25 percent of disintegrating agent and the balance of carrier. The simazine water dispersant granule has the following four advantages: 1. since the simazine water dispersant granule is free from organic solvent, the damage to ecological environment is mitigated and the production cost is lowered; 2. the toxic action on the applicators is significantly decreased; 3. after being made into water dispersant, the simazine water dispersant granule is characterized by good dispersibility and suspension property, high effective component content and stable physical and chemical properties, can expand the application scope of the drug, extend the persistent period, improve the drug effect, save organic solvent, and do no harm to environment, and has the advantages of both wettable powder and suspending agent; and 4. the granule is convenient to be packaged and transported.

Description

technical field [0001] The invention relates to a pesticide herbicide, in particular to a simazine water-dispersible granule and a preparation method thereof. technical background [0002] Simazine is a highly invasive systemic herbicide, which mainly controls grass weeds and broad-leaved weeds. It is applied in the early or mid-emergence stage before the weeds emerge. [0003] Most of the current simazine preparations are suspension concentrates and wettable powders, which have excellent herbicidal activity and are quickly degraded in the environment. The disadvantages are that the active ingredient content is low, unstable, poor suspending and wettability, and drug efficacy. Poor, easy to generate dust during packaging and transportation. [0004] Water-dispersible granules are new formulations developed on the basis of wettable powders and suspension concentrates. Wettable powder is a traditional solid dosage form, and most fungicides and some herbicides are processed i...

AI Technical Summary

Problems solved by technology

But in the promotion and application, there are also certain shortcomings

The formulation and process technology of the suspension is more complicated than that of the wettable powder, and there are many influencing factors. After a long time of storage, stratification and sedimentation often occur. When used, the sediment is not easy to resuspend, and it cannot be poured out. Even if it is poured out, it will seriously stick to the wall, which is not good Metering, and the packaging material is not easy to handle

Coupled with the large amount of packaging, storage, transportation, inconvenience, etc., for this reason, pesticide processing workers have made further research and introduced a more ideal new dosage form of water-dispersible granules
