Description

A kind of agricultural chemicals synergist composition and application thereof
Technical field
The invention belongs to pesticide field, it is specifically related to a kind of agricultural chemicals synergist composition and application thereof.
Background technology
Oil of Eucalyptus (eucalyptusoil) is also known as eucalyptus oil, refer to the essence oil that extraction methods such as adopting wet distillation is extracted from the leaf of blue gum, folium eucalypti tree, camphor tree etc., branch, for colourless or yellow, delicate fragrance are pungent, be insoluble to water, be soluble in the multicomponent mixture of organic solvent, main component 1,8-cineole.
Citric acid mono-glycerides (CMG) is also known as citric acid glycerin fatty acid ester, citric acid glyceride, citric acid list, it it is the esterification products of molecule distillating monoglyceride and citric acid, it by the carbochain in hydrophilic radical and fatty acid molecule of the-OH in citric acid molecule and-COOH for hating water base, in parents' molecular structure, belong to anion surfactant.
Prevent and treat in process in agricultural pest, conventional atomizer is mostly used to carry out spraying pesticide liquid at present, when liquid sprays application in crop surface, only have that 20-30% liquid is auxiliary to be opened up in crop blade face, but the auxiliary liquid opened up on crop blade face can because of the reason such as solar irradiation and temperature rapid evaporation; Other 70-80% liquid because opening up, interior suction poor-performing be formed in big drop and tumble in water or field, thus cause agricultural chemicals utilization ratio low, agricultural chemicals mu usage quantity increases, the problems such as the anti-effect of disease and pest is low, and contaminate environment is big.
Therefore urgent need a kind of inert ingredient composition to solve in prior art the various defects existing for conventional spraying.
At present, we not yet find relevant patent and the document report of the agricultural chemicals synergist composition of Oil of Eucalyptus and citric acid direactive glyceride.
Summary of the invention
The present invention is directed to the deficiency that aforesaid method proposes, a kind of inert ingredient composition is provided, it can reduce the evaporation of crop surface liquid, play moisture-keeping function, increase the interior absorption of medicament in crop surface simultaneously, improve the utilization ratio of agricultural chemicals, it is to increase the prevention effect of disease and pest, and then reduce drug cost.
For realizing above-mentioned object, the technical scheme of the present invention is:
A kind of agricultural chemicals synergist composition, this builder composition is made up of Oil of Eucalyptus and citric acid direactive glyceride; Described builder composition accounts for the 1%-10% of pesticide preparation mass percent.
In the present invention, as further explanation, the mass ratio of described Oil of Eucalyptus and citric acid direactive glyceride is 2: 1��1: 12.
In the present invention, as further preferably, the mass ratio of described Oil of Eucalyptus and citric acid direactive glyceride is 1: 1��1: 9.
The using method containing agricultural chemicals synergist composition of the present invention, it is in the pesticide preparation containing one or more combinations of Avrmectin, Affirm (Merck Co.), Cypermethrin and pymetrozine.
The present invention contains agricultural chemicals synergist composition, and it is applicable to the preparation of aqueous emulsion, missible oil, wettable powder or micro-emulsion form.
It is uniformly mixed by the agricultural chemicals synergist composition of the present invention when preparing pesticide preparation together with former medicine, Ricinate, solvent or emulsifying agent or carrier, and the conventional machining technique according to each formulation of agricultural chemicals is prepared into Pesticidal products.
Ricinate is polyoxyethylene nonylphenol ether, aliphatic alcohol polyoxyvinethene phosphate, fatty alcohol-polyoxyethylene ether graft copolymer, sodium lignosulfonate, sodium methylene bis-naphthalene sulfonate, pull open powder, at least one in tristyrylphenol polyoxyethylene ether, castor oil polyoxyethylene ether, thermally coupled distillation columns, fatty alcohol-polyoxyethylene ether and APG.
Solvent is at least one in dimethylbenzene, pimelinketone, methylcarbonate and water.
Emulsifying agent be agriculture breast 600# phosphoric acid ester and agriculture breast 600# at least one.
Carrier is at least one in white carbon black and kaolin.
The component of the present invention is commercially available prod.
The density of the Oil of Eucalyptus of the present invention is 0.905��0.925, purposes is extensive, can be used for preparing cosmetics, prepare the essence such as cough-relieving agent, collutory, insecticide ointment and preparation toothpaste, tooth powder, candy for medicine, it is also possible to be used as the medicinal raw materials such as oral cavity, rhinitis use, menthocamphorate. Testing through applicant and find that Oil of Eucalyptus is except having above-mentioned effect, it also can be applicable to play in pesticide preparation moisture-keeping function, reduces the rapid evaporation being sprayed at liquid on crop surface or weeds, shortens the evaporation time of liquid, it is to increase the utilization ratio of agricultural chemicals.
Citric acid direactive glyceride HLB value 4-6 of the present invention, has the effects such as emulsification, dispersion, chelating, anti-oxidant synergy, resisting starch ageing and control fat aggegation. Citric acid direactive glyceride in the present invention institute's role mainly strengthen the avidity of the wax layer of liquid and crop surface, reduce the contact angle of liquid and crop surface, make the liquid quick auxiliary expansion of energy spraying in crop surface, reduce drop and tumble in water or field.
Compared with prior art, the useful effect that the present invention has is:
Oil of Eucalyptus and citric acid direactive glyceride by the combination of rational proportioning, are applied in pesticide preparation to play the rapid evaporation reducing and spraying at crop or weeds liquid on the surface, shorten its evaporation time by the present invention, and the time of evaporation is at 11��32S; Increasing pesticide droplet expanding area, expanding area can reach 3mm simultaneously2Left and right, enhancing crop or weeds, to the absorption of medicament, improve the agricultural chemicals utilization ratio of pesticide solution greatly, improve the prevention effect of disease and pest or the preventive effect of weeds, prevention effect can reach more than 90%, reduces the environmental pollution that agricultural chemicals runs off and causes, and then reduces drug cost. But alone Oil of Eucalyptus or citric acid direactive glyceride, it is to the prevention effect of disease and pest or the preventive effect of weeds is all undesirable, both compositions being not so good as the proportioning that the application limits far away, the prevention effect that both combine is good more than alone prevention effect, great popularization in technical field of pesticide.
