Microcapsule suspension concentrate containing triallate and preparation method thereof

Abstract

The invention discloses a microcapsule suspension concentrate containing triallate and a preparation method thereof. The microcapsule suspension concentrate comprises the following components in percentage by weight: 10-50% of the triallate, 5-20% of organic solvent, 1-10% of wall material, 1-5% of surfactant, 1-5% of dispersant, 0.01-2% of pH regulating agent, 0.01-1% of viscosity regulating agent, 0.1-1% of anti-freezing agent, 2-5% of preservative and the balance of water. The preparation method of the microcapsule suspension concentrate containing the triallate comprises the following steps of: firstly dissolving monomers of the triallate and the wall material in the organic solvent to get an organic phase, adding the organic phase into a water phase for dissolving the surfactant, uniformly mixing, then adding the dispersant, the anti-freezing agent, the preservative, the pH regulating agent and the viscosity regulating agent, and uniformly stirring to get a product. The microcapsule suspension concentrate containing the triallate, disclosed by the invention, improves the stability and safety of the triallate, reduces the harm to crops and effectively prevents the efficacy of the triallate from being reduced due to strong volatility, thereby reducing the dosage and lowering the cost.

Description

technical field [0001] The invention relates to a product processed by pesticide technology, in particular to a microcapsule suspension which takes the herbicide tricamba as an active ingredient and a preparation method thereof. Background technique [0002] Tricamba is an efficient and selective herbicide for controlling wild oats. It is mainly used for soil treatment and absorbed through the bud sheath and the first cotyledon during the germination of wild oats. However, it is highly volatile, and the soil must be mixed immediately after application, and the crop seeds cannot directly contact the agent. Usually in order to avoid phytotoxicity, it is necessary to separate the sowing depth and the application layer. [0003] Compared with conventional pesticide formulations, microcapsule preparations (microcapsule suspensions, microcapsule granules) have the advantages of prolonging the special effect period, improving the effective utilization rate of pesticides, avoiding ...

AI Technical Summary

Problems solved by technology

[0003] Compared with conventional pesticide formulations, microcapsule preparations (microcapsule suspensions, microcapsule granules) have the advantages of prolonging the special effect period, improving the effective utilization rate of pesticides, avoiding the decomposition and loss of pesticides caused by the external environment, reducing toxicity and phytotoxicity, and reducing pesticide damage. Due to the characteristics of environmental pollution, microcapsule preparations have become one of the important development directions for the processing of pesticide formulations. Processing wild wheat camb into microcapsule suspensions is expected to solve the above problems, but there is no domestic preparation of wild wheat camb into microcapsules.
