Abstract
The metalaxyl-carbosulfan micro emulsion consists of metalaxyl 1-20 wt%, carbosulfan 3-30 wt%, non-ionic surfactant 10-20 wt%, anionic surfactant 10-20 wt%, solvent 10-50 wt% and water 15-55 wt%. The metalaxyl-carbosulfan micro emulsion has water used as solvent and no toxic solvent component and is environment friendly. It has small pesticide particles and thus raised bioavailability.
Description
Technical field
The present invention relates to a kind of pesticidal preparations, be specifically related to a kind of agricultural chemicals microemulsion, more specifically relate to a kind of metalaxyl carbosulfan composite microemulsion and preparation method thereof.
Background technology
Metalaxyl, adopted name: metalaxyl; Chemical name: N-(2-methoxyl group acetyl group)-N-(2, the 6-3,5-dimethylphenyl)-DL-α-An Jibingsuan methyl esters; Other titles: the many Mils of thunder, auspicious toxin, good.Pure product are colourless crystallization, 71.8～72.3 ℃ of fusing points.Can prevent and treat the disease that phycomycetess such as downy mildew, eqpidemic disease, late blight, cotton disease, white blister cause.The tool systemic action.Can be absorbed by plant roots, stem, leaf, and be transported to each organ of plant with moisture running in the plant corpus.Excellent protection and therapeutic action are arranged.
Carbosulfan, adopted name: pacify prestige (carbosulfan) well; Chemical name: 2,3-dihydro-2,2-dimethyl benzofuran-7-base-N-dibutylamino sulfenyl-N-methyl carbamate; Other titles: good year winter, Marshall, Adrantage.Former medicine be crocus to the brown thick liquid, 124～128 ℃ of boiling points, 95 ℃ of flash-points (closed-cup method).This product is a carbamate insecticide, anticholinesterase.It is the low derivative that poisons of carbofuran, insecticidal spectrum is wide, can anti-eliminate aphis, mite, wireworm, Atomaria linearis, beet flea beetle, colorado potato beetle, fruit tree leaf roll Hubei Province, apple cecidomyiia, codling moth, tea Empoasca spp, the heavy and scale insect of the little food heart of pears, dosage 100-1000 gram/mu.Make soil treatment, can prevent and treat soil insect (Diplopoda, Elateridae, Symphyla), crop is citrus, potato, paddy rice, beet etc.Be mainly used in citrus, the integrated control of various insects on the vegetables, characteristics such as it is fat-soluble good to have, and interior absorption is good, residual quantity is low, safe in utilization.Field control effectiveness test proves that this product antagonism cotten aphid, citrus rust mite, leaf miner, aphid, Aleurocanthus spiniferus, scale insect, vegetables thrips, cabbage caterpillar, beet armyworm etc. have higher control efficiency.This product production process does not have waste residue substantially, and waste gas has only a small amount of waste water, adopts the burning method that generally uses in the world to handle and can reach discharging standards.Carbosulfan is a carbamate chemicals for agriculture, i.e. the low derivative that poisons of carbofuran agricultural chemicals belongs to highly effective and safe, interior absorption, killing insects by touching miticide easy to use, is one of comparatively ideal alternative kind of highly toxic pesticide Ke Baiwei.
But, because metalaxyl and carbosulfan are water-fast organic compound, the product of Shi Yonging is mainly unitary agent in the market, and be the animal oil product, because the missible oil product has added a large amount of poisonous organic solvents such as dimethylbenzene in production and process, will produce bigger pollution to environment and ecology during use; Owing to form emulsion in the use of missible oil product, the particle of active ingredient is bigger simultaneously, and consumption is big, assimilation effect is poor.So developing a kind of is that the metalaxyl and the carbosulfan composite microemulsion of dispersion medium is significant with water.
Summary of the invention
The technical issues that need to address of the present invention are to disclose a kind of metalaxyl carbosulfan composite microemulsion and preparation method thereof, to overcome the above-mentioned defective that existing technology exists, satisfy the needs of relevant department.
Technical conceive of the present invention is such:
Metalaxyl and carbosulfan are public nuisance-free agricultural chemicals commonly used in the agricultural production, are main component with it, and it is combined into the agricultural chemicals microemulsion that integrates desinsection and sterilization for can a dispenser double effects in the agricultural production.For this reason, the inventor filters out the emulsifier and the solvent that can be used for preparing the metalaxyl carbosulfan composite micro emulsion by a large amount of experiments, has proposed following technical scheme:
