Description

A kind of aqueous pesticide and preparation method thereof
Technical field
The present invention relates to pesticide field, specifically, the present invention relates to a kind of aqueous pesticide and preparation method thereof.
Background technology
The widely-used meeting of chemical pesticide pollutes environment, and people and animals are also had certain murder by poisoning, therefore, reduces toxicity, improves the inexorable trend that drug effect is the agricultural chemicals development.And there are problems such as scarce capacity, cost height in China's present pesticide original medicine research and development, research and develop by formulation therefore that to reduce toxicity, improve drug effect be a kind of economy mode efficiently.
At present, China is more single in the formulations of pesticide, and 70-80% is missible oil and wetting powder in all preparations.Obviously, this far can not adapt to the variation of current agricultural production development to the agricultural chemicals demand, and has influenced the marketing and the service life of Pesticidal products to a great extent.Therefore, more should pay attention to the transformation of existing formulation and the novel form that research and development meet production and environmental requirement.
The novel form of agricultural chemicals also can increase new feature to agricultural chemicals, more can give full play to the action characteristic of former medicine self, overcome and remedy the deficiency of the original formulation of agricultural chemicals, toxicity and excitant to people and animals are all lower, and can alleviate poisoning to crop, improve physico chemistry and biological property, enlarge range of application, prolong the service life of medicament etc.
Comparatively convenient and what generally use is liquid formulation in the agricultural chemicals, wherein using maximum formulations is missible oil.Missible oil needs to use a large amount of organic solvents in process, as benzene,toluene,xylene or the like, the use of a large amount of organic solvents not only causes the waste of industrial chemicals, and since the combustibility of solvent on transportation, storage and container selection, also be restricted.Simultaneously, brought very big murder by poisoning for environment and human health.Developed country limits or forbids using in a large number the pesticide new variety registration of toxic organic solvent preparations such as benzene,toluene,xylene from sustainable development target.Therefore, reduce or avoid these virulent organic solvents, develop the trend of the times that novel liquid formulation has become the agricultural chemicals development.Wherein, Water-borne modification is exactly one of dominant direction of formulations of pesticide development.A series of water base property novel forms such as aqueous solvent, microemulsion, emulsion, suspending agent, suspended emulsion, microcapsule formulations etc. have appearred in recent years.
Aqueous solvent comprises: active ingredient forms the homogeneous liquid preparation of true solution behind soluble concentrate (soluble concentrate the is called for short SL) dilute with water.The aqueous solution preparation of aqua (aqueous solution is called for short AS) active ingredient and auxiliary agent.But active ingredient forms the glue-like preparation of true solution behind glue (water soluble gel the is called for short GW) dilute with water.China is used for the former medicine content generally not high (as dimehypo) of process water solvent, is difficult to be processed into the aqueous solvent of high concentration, thereby packing charges and storage fee are with higher.
External principal item has 41% farming to reach (aqueous solvent that is the processing of 360g/l glyphosate and 15% auxiliary agent), 48% Dicamba, 20% Gramoxone and 25% prowers aqueous solvent etc.China's principal item has glyphosate and amine salt, 2-first-4-chlorine, jinggangmeisu, ethrel, dimehypo, single carbonamidine aqueous solvent etc.
