Prochloraz-containing sterilizing micellar emulsion and its preparing method

Abstract

The invention discloses a sterilizing micro emulsion contained prochloraz about 5-30%, solvent 5-15%, emulsifier 10-20%, antifreeze agent 5-10%, other as deionized water, which is 100% totally, or adding diniconazole or myclobutanil 2%-3% to the above formulation. The process for preparing is that, firstly putting prochloraz, diniconazole or myclobutanil into solvent under heating condition and mix around with adding antifreeze agent and emulsifier, then accelerating mixture and entering deionized water slowly after all that material is well-proportioned, whereafter continuing mixing and heating the materials up to 70 deg.C-80 deg.C, the production can be gained after mixture changes from W / O type to O / W type and presents liquid of uniform phase. The invention applies to prevention and cure the pathogen of pseudomonas, ascomycetes, basidiomycetes, pyrenophora and rostrum bacterium with high effect, with simple technique, safety to storage and transport, no danger to human and animals, much less pollution to environment.

Description

technical field [0001] The invention relates to a bactericide, in particular to a bactericidal microemulsion with prochloraz or a mixture of prochloraz and other bactericides as an active ingredient and a preparation method thereof. Background technique [0002] As people pay attention to the living environment, it is required to reduce the environmental pollution caused by the use of pesticide products. In order to meet this social requirement, in the development of pesticide products, while focusing on the development of new varieties of pesticides with low toxicity and high efficiency, higher requirements are put forward for pesticide preparations, and the development of pesticide preparations is required to be solidified and water-based. [0003] Prochloraz is a broad-spectrum fungicide, which can treat and eradicate various diseases on field crops, fruits, vegetables, turf and ornamental plants, and has anti-rot effects on fruits and vegetables during storage.
