Description

A kind of Herbicide Jing quizalofop-ethyl EC containing Synergistic plant oil and preparation method thereof
Technical field
The invention belongs to Agrotechnical formulation field, more particularly to a kind of Herbicide Jing quizalofop-ethyl EC containing Synergistic plant oil And preparation method thereof.
Background technology
Quizalotop-ethyl is a kind of arylphenoxy phenoxy propionic acid selectivity, inner sucting conduction type, cauline leaf process low toxicity herbicide;For Selective post-emergence herbicide, leaf Assimilation and conductivity, accumulate and destroyed in top, internode separate living tissue, lose power of regeneration, stop Grow and wither;Quizalotop-ethyl is mainly processed into missible oil use, and missible oil is one of basic formulation of agricultural chemicals, compared with other formulations, It is formed and processing technology is simple, and preparation stored stability is good, easy to use, and prevention effect is good;But contain in traditional missible oil Low, the volatile petroleum aromatic class organic solvent of a large amount of flash-points, therefore require strict in produce, store and transport and use etc., and And environment is easily polluted after use;In recent years, with concern of the people to food and Environmental security, organic solvent in agricultural chemicals commodity Side-effect problem has been highly valued, and organic solvent content is high especially in high activity emulsifiable concentrates for agricultural chemicals, in addition rhinestone in recent years The problems such as soaring solvent cost brought of oil price lattice improves has caused the extensive concern of people.
Under the pressure of the pressure of environmental protection, resource and cost, the use of traditional aromatic hydrocarbon solvent is gradually restricted;Exploitation easily drop Solution, reproducible non-petroleum class solvent be a kind of approach to solve the above problems, and its solvability to various active compounds, into This, on security of crop etc. be influence such solvent can promotion and application important limiting factor.
The content of the invention
The present invention solves above-mentioned technical problem present in prior art, there is provided a kind of herbicide containing Synergistic plant oil Quizalotop-ethyl missible oil and preparation method thereof.
To solve the above problems, technical scheme is as follows:
A kind of Herbicide Jing quizalofop-ethyl EC containing Synergistic plant oil, include the raw material of following parts by weight:
Quizalotop-ethyl, 1~20%;
Synergistic plant oil, 5~50%;
Builder, 1-3%;
Emulsifying agent, 7~35%;
Cosolvent, 20~50%;
Synergistic plant oil is soybean oil, rapeseed oil, cottonseed oil, coconut oil, castor oil, turpentine oil, enriching vegetable oil, The group of any one or a few in methyl oleate, isooctyl oleate, sunflower oil, peanut oil, olive oil, palm oil, corn oil Close;
Vegetable oil is a major class of grease, is widely present in nature, resource very abundant, and there is biology completely to drop for it Xie Xing, renewable, small toxicity, biodegradation is fast, Environmental compatibility is good, flash-point is high, stores and transports the advantages that safe, meets pesticide in future Formulation develops the requirement to solvent, therefore possesses the potentiality for substituting traditional agricultural chemicals organic solvent in theory, has preferably society And ecological benefits;
The builder is black tea tincture.
Preferably, the emulsifying agent is that APES formaldehyde condensation product, polyoxyethylene laurel ether, nonyl phenol gather Oxygen vinethene, alkylaryl APEO, Tween-80, calcium dodecyl benzene sulfonate, neopelex, PO-EO The combination of any one or a few in block polyether.
Preferably, the cosolvent is in cyclohexanone, acetone, DMF, DMSO, 1-METHYLPYRROLIDONE, dimethylbenzene, toluene Any one or a few combination.
The preparation method of Herbicide Jing quizalofop-ethyl EC containing Synergistic plant oil, comprises the following steps, by Quizalotop-ethyl It is dissolved in the mixture of the Synergistic plant oil, builder and cosolvent, adds emulsifying agent, stir, that is, obtains outer See limpid bright Quizalotop-ethyl missible oil.
Relative to prior art, advantages of the present invention is as follows,
The Herbicide Jing quizalofop-ethyl EC containing Synergistic plant oil of the present invention, using vegetable oil as pesticide solvent, its is right The solubility of Quizalotop-ethyl agricultural chemicals is higher;Compared with conventional solvent, its flash-point is higher, and more than 100 DEG C, peace is compared in production, storing Entirely;Volatility is weak, small to the producer and user's excitant;Under the synergistic effect of builder, Quizalotop-ethyl missible oil decomposes Rate is low, develops no bad influence to soybean, seedling growth of rice, the drying time of decoction significantly extends, the deposition of medicament Amount improves, and solvent strength is higher, and effect is more obvious;Reduce environmental pollution.Aromatic organic solvent in conventional missible oil Content is up to 65~80%, and such solvent is reduced to 20~50% in the missible oil of the present invention, thus reduces organic solvent pair The pollution of environment;
The Herbicide Jing quizalofop-ethyl EC preparation method of the Synergistic plant oil of the present invention is simple, and mild condition is green.
