Abstract
The invention provides application of a low-melting-point insoluble substance to a green pesticide solvent and the low-melting-point insoluble substance, and relates to the field of pesticide preparation, in particular to a green pesticide solvent. By aiming at the defects in the prior art, the invention provides the nontoxic green pesticide solvent favorable for plant growth. The solvent consists of R<1>R<2>R<3>N<+> X<-> and urea. In the preparation process, raw materials are stirred and mixed at 80 DEG C, and transparent viscous liquid is formed, wherein the R1 is any one of methyl, benzyl or ethyl; the R2 is methyl; R3 is ethoxy or acetyl hydroxyethyl; the X<-> is one of Cl<->, F<-> or NO3. The water solubility of the pesticide solvent is high, so that the pesticide solvent can be used for various water-soluble or hydrophilic active compound solvents; the solvent has low toxicity and can be degraded; the use is safe; the solvent has a good regulation effect on the plant growth; the pesticide effect of the pesticide is ensured; meanwhile, the crop yield increase is realized; the solvent storage performance is good; the solvent cannot be volatilized and layered; the raw material cost of the solvent is low; the production is simple; the large-scale production is convenient.
Description
Technical field
The present invention relates to field of pesticide preparation, particularly relate to a kind of environment friendly agricultural solvent.
Background technology
Shi Ge large agricultural country of China, agricultural chemicals is in great demand, in the preparations such as the soluble liquid of being gone into operation by domestic-developed in recent years, introduce the omnifarious polar organic solvents such as dimethyl formamide, decyl amide, cyclohexanone, dichloroethane, butanols, octanol, isoamyl alcohol in a large number.By 2004, this series products obtaining legal procedure reached tens, and this series products is transparency liquid, water-soluble, and with " Environmental security " for slogan, development speed is very fast.But the in fact many harm of solvent to environment and personal safety has exceeded benzene kind solvent, if do not controlled, when benzene class organic solvent fails to be inhibited, the plant protection of China is faced with again the threat of the larger solvent contamination of new class toxicity.
Summary of the invention
The object of the invention is the defect existed for above-mentioned existing pesticide solvent, provide a kind of safety and low toxicity and the low melting point the helping plant growth application of molten thing on environment friendly agricultural solvent and low melting point eutectic thereof altogether.
The invention provides the application of molten thing on environment friendly agricultural solvent altogether of a kind of low melting point.
The present invention also provides the low melting point being applied to environment friendly agricultural solvent molten thing altogether, and described low melting point is total to molten thing by R

The present invention has following beneficial effect:
This low melting point has the advantage of good water solubility when altogether molten thing is applied to pesticide solvent, can be used for the solvent of the various water-soluble or former medicine of hydrophily; This solvent Storage is good, and solvent is non-volatile, not stratified, solvent low toxicity degradable, use safety; To plant growth, there is regulating action, while guarantee pesticide efficacy, realize increasing income of crops; Low in raw material price, produces simple, is convenient to large-scale production.
