2O, chemical name 4-bromo-2-(4-chlorphenyl)-1-(ethoxyl methyl)-5-(trifluoromethyl) pyrroles-3-nitrile has another name called and eliminates, and being American Cyanamid Company found and the fragrant pyroles insecticidal/acaricidal agent of exploitation in the later stage eighties.This agricultural chemicals is successfully developed by the chemical constitution transformation to natural antibiotics.
This compound is a kind of preinsecticide, itself insect there is not the poisoning effect, after its mechanism of action is insect's food-taking or contact capillary, in insect bodies, change the tool insecticidal active compound into through mixed-functional oxidase, act on target polypide intracellular plastochondria then, destroy the physiology course that oxidative phosphorylation ADP is transformed into ATP.ATP is the chemical energy that cell earns a bare living, and can not produce ATP, and cell just stops vital functions, finally causes insect death.Used most of pesticide species on this mechanism of action and the market, all different as organic phosphor, pyrethroid, Avermectin etc.Therefore, this agricultural chemicals can be prevented and treated the insect that these agricultural chemicals is produced resistance, perhaps delays the generation of pest resistance to insecticide with these agriculture chemical compoundings.Through the developmental research in more than 20 years, capillary many countries and regions were worldwide successfully developed and are come into the market.Its high-efficiency broad spectrum, characteristic of wide insecticidal spectrum, especially the excellent preventive effect to difficult pest controls such as diamond-back moth, beet armyworms is subjected to the market favor.
The formulation that capillary is registered in the market mainly contains three kinds of missible oil, microemulsion, suspending agent, and not seeing has the aqueous emulsion registration, does not also see the report of capillary and the composite aqueous emulsion of other former medicine components.
Summary of the invention
The objective of the invention is to provide in order to overcome the defective that above-mentioned prior art exists a kind of safe in utilization, the feature of environmental protection good, improve drug effect, enlarges insecticidal spectrum, the lower-cost capillary aqueous emulsion and preparation method thereof that contains.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: the insecticidal active ingredient of this aqueous emulsion is by a kind of composite the forming among capillary or capillary and the X, wherein X is Biphenthrin, chlopyrifos or Nitenpyram etc., mass ratio is in capillary and the composite aqueous emulsion of other several components: capillary/X=0.1-99.9/9 9.9-0.1, wherein, the capillary mass percent is 1%～30%; Also add solvent, emulsifier, bleeding agent, synergist, thickener, antifreezing agent or defoamer and water in the aqueous emulsion.
Its constituent content (in the aqueous emulsion weight portion): 1～30 part of capillary, 0～30 part of Biphenthrin, 0～40 part of chlopyrifos, 0～30 part of Nitenpyram, 3～30 parts of solvents, 3～15 parts of emulsifier, 0～5 part of thickener, 0～10 part of bleeding agent, 0～20 part of synergist, 0～5 part of stabilizing agent, 0～5 part of antifreezing agent, 0～1 part of defoamer, water is supplied 100 parts.
Capillary and Biphenthrin mass ratio are 30: 1-0.03: 1.
The mass ratio of capillary and chlopyrifos is 4: 1-0.025: 1.
The mass ratio of capillary and Nitenpyram is 30: 1-0.03: 1.
Described solvent is selected from one or more mixture of methyl alcohol, dimethylbenzene, cyclohexanone, ethyl acetate, carbon 9 aromatic hydrocarbons or methyl naphthalene.
Described emulsifier is selected from one or more the mixture in fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, phenethyl phenol polyethenoxy ether, alkylaryl polyoxyethylene polyoxypropylene ether, aliphatic alcohol polyoxyvinethene phosphate, alkylphenol polyoxyethylene phosphate, phenethyl phenol polyethenoxy ether phosphate, alkylaryl polyoxyethylene polyoxypropylene ether phosphate, the calcium dodecyl benzene sulfonate.
Described bleeding agent is selected from azone, thiophene ketone, organosilicon, oozes among T or the JFC one or both soon; Synergist is selected from one or both in Butacide or the synergy phosphorus.
Described thickener is selected in xanthans, gelatin, cyclodextrin, polyvinyl alcohol, cellulose and derivative thereof or the modified starch water-soluble high-molecular substance one or both for use; Described antifreezing agent is selected from one or both the mixture in ethylene glycol, the glycerine; Defoamer is an organosilicon.
The preparation method who contains the capillary aqueous emulsion comprises following processing step: (annotate: the consumption of following each component is all counted by weight)
(1) makes oil phase
1～30 part of capillary or add for 3～30 parts with solvent with 0～40 part of 0～30 part of Biphenthrin, chlopyrifos is in the same place, and stirs it is dissolved fully; Add 3～15 parts of emulsifier, 0～10 part of bleeding agent, 0～20 part of synergist again, stir into even oil phase.
(2) make water
0～30 part of Nitenpyram, 0～5 part of thickener, 0～5 part of stabilizing agent, 0～5 part of antifreezing agent, 0～1 part of defoamer and water are complemented to 100 parts be added in and be mixed together, stir into the homogeneous water.
(3) emulsification pretreatment
Under high-speed stirred, oil phase is added aqueous phase, form finely disseminated emulsion liquid, promptly get aqueous emulsion.Speed of agitator is 1000～5000 rev/mins, and mixing time is 30～60 minutes.
Aqueous emulsion of the present invention is owing to contain or only contain a small amount of organic solvent, thus can avoid producing with transporting procedures in inflammable and explosive phenomenon.This formulation does not have unpleasant poisonous smell, and is little to eye irritation, reduced the pollution to environment, improved the safety to production, storing and user greatly.In addition, aqueous emulsion is a matrix with the water of a large amount of cheapnesss, substitute organic solvent, the emulsifier consumption is 3%～15%, and cost is low, and Environmental compatibility is good, though increased auxiliary agents such as some antifreezing agents, stabilizing agent, but along with the raising of International Crude Oil, the solvent price climbs up and up, and makes aqueous emulsion than corresponding missible oil bigger advantage be arranged on cost.Because with an organic solvent minimizing, the pressure of environment is diminished, the toxicity of warm blooded animal is reduced, make that the toxicity to non-target organism reduces.Capillary is processed into aqueous emulsion and is re-dubbed aqueous emulsion with organic phosphates, chrysanthemum ester class, nicotinoids, can improve drug effect, enlarge insecticidal spectrum, delay the development of pest resistance to insecticide, reduce cost, reduce environmental pollution, therefore have the wide development application prospect.
