Description
Technical field
The present invention relates to a kind of 0, the aerosol that 0-dimethyl-0-(2, the 2-dichloroethylene) phosphates (also claiming dichlorvos) and 2-tertiary butyl-5-(4-tertiary butyl benzylthio)-4-chloro-2H-pyridazin-3-one (also claiming pyridaben) is mixed (also claim dichlorvos rattle away mite aerosol or thermal fog) and preparation method thereof technology.
Background technology
The dichlorvos mite insecticide of rattling away is the insecticide that a kind of dichlorvos and pyridaben are mixed, and is mainly used to prevent and treat citrus red mite, aphid, damage by disease and insect such as mite class.Studies show that after dichlorvos and pyridaben mixed by a certain percentage, the preventing disease and pest effect also promptly had synergistic effect than single separately agent height of identical active constituent content.Mostly be missible oil, wetting powder and aqueous suspension owing to what prevent and treat above-mentioned insect pest use at present, need convert a large amount of water atomized water sprays when using, having under the situation at water source, wasted the water of a large amount of preciousnesses, and do not had under the situation at water source, the spray medicine can't be implemented.
At present the dichlorvos mite aerosol of rattling away is not seen data report and product appearance both at home and abroad.Said preparation is a very promising novel formulation.
Summary of the invention
At the shortcoming of prior art, technical problem to be solved by this invention provides a kind of dichlorvos mite aerosol and preparation method thereof of rattling away.Its product has does not convert water, atomizes, and consumption is few, safety easy to use, advantage such as environmental pollution is little; Its preparation method technology is simple, and is with low cost.
The technological means that the present invention solves described technical problem is, design a kind of dichlorvos mite aerosol of rattling away, contain 0,0-dimethyl-0-(2, the 2-dichloroethylene) phosphate and 2-tertiary butyl-5-(4-tertiary butyl benzylthio)-4-chloro-2H-pyridazin-3-one is characterized in that also containing complexed surfactant, high boiling solvent and cosolvent, its percentage by weight prescription is:
0,0-dimethyl-0-(2, the 2-dichloroethylene) phosphate and 2-tertiary butyl-5-(4-tertiary butyl benzylthio)-4-chloro-2H-pyridazin-3-one 5-40%;
Cosolvent 0.1-10%;
High boiling solvent 20-90%;
Complexed surfactant 0.1-30%;
Said high boiling solvent is one or more in No. 2, aromatic hydrocarbons, No. 3, atoleine, white oil, o-dichlorohenzene, diethylene glycol (DEG), triethylene glycol;
Said cosolvent is methyl-sulfoxide, N, one or more in dinethylformamide, ethylene glycol, the propane diols;
Said complexed surfactant is alkyl benzene calcium sulfonate, alkylphenol polyoxyethylene, phenethyl phenol polyethenoxy ether, alkylphenol polyoxyethylene formaldehyde condensation products, one or more in castor oil polyoxyethylene ether, the secondary alkanol APEO;
Described each constituent content sum is 100%.
Complexed surfactant of the present invention can be known alkyl benzene calcium sulfonate, and preferably No. 500, the farming breast.Formulation content is 0.1-10%; Alkylphenol polyoxyethylene is OP-4, OP-7 preferably, formulation content 0.1-5%; The phenethyl phenol polyethenoxy ether is agricultural emulsifier NO preferably, formulation content 0.1-5%; The alkylphenol polyoxyethylene formaldehyde condensation products is Nongru-700 number preferably, formulation content 0.1-3%; Castor oil polyoxyethylene ether is EL-40 preferably, formulation content 0.1-4%; Secondary alkanol APEO is JFC preferably, formulation content 0.1-3%.
Described high boiling solvent can be known many alkyl-substituted aromatic hydrocarbons, and preferably aromatic hydrocarbons is No. 2, No. 3; The atoleine hydrocarbon of many carbon, preferably atoleine; How halogen-substituted, o-dichlorohenzene preferably; High carbon alkane, preferably white oil; The alcohols of dimerization trimerization, preferably diethylene glycol (DEG), triethylene glycol.Described high boiling solvent is meant the solvent (hereinafter to be referred as solvent) more than boiling point 〉=200 ℃.
The rattle away further feature of mite aerosol of dichlorvos of the present invention is that described dichlorvos is rattled away the solid grain of mite aerosol through≤2 μ m.
The further technical problem to be solved of the present invention is the rattle away preparation method of mite aerosol of the described dichlorvos of design, it is characterized in that at first high boiling point cosolvent, the mixed solvent of described component and ratio are added in the modulation kettle, under agitation add described 0,0-dimethyl-0-(2, the 2-dichloroethylene) phosphate and 2-tertiary butyl-5-(4-tertiary butyl benzylthio)-4-chloro-2H-pyridazin-3-one, continue to stir and be heated to 50 ℃, after treating that former medicine dissolves fully, the complexed surfactant of described component and ratio is added wherein; Under agitation, filter, check promptly up to standard to forming clear solution.
The contrast prior art, advantage of the present invention is:
1. strong ability to resist splash erosion.Conventional pesticide preparation missible oil, wetting powder and aqueous suspension agent etc., need convert a large amount of water sprays during use, its droplet can only partly deposit on crop, it is a lot of to run off, even being deposited on droplet on the crop meets rain and also can be washed away at once, and smoke particle of the present invention is deposited on back on the crop even rainfall is not immediately washed away yet, and the operation of also can spraying when spotting, and has very strong ability to resist splash erosion.
2. improved drug effect.Usually weigh behind several fungicide compoundings whether synergy, except that representing, represent its synergy degree at indoor its co-toxicity of measuring with field efficacy.The specific targets of co-toxicity are normally represented with co-toxicity coefficient: co-toxicity coefficient＜70 are antagonism; 70---150 is summation action; 150---200 are synergistic effect;＞200 is the notable synergistic effect.The dichlorvos of the present invention co-toxicity coefficient that the mite aerosol measures of rattling away is 180, so have synergistic effect.Because the average grain diameter of the former medicine particle of the present invention is minimum, reach≤2 μ m, particle than the wetting powder (average grain diameter 44 μ m) of prior art and aqueous suspension (average grain diameter 〉=5 μ m) is little a lot, in the drift process in case contact just easier attaching on it of crop, and wide coverage, disperse more evenly, drug effect is higher more than 20% than prior art.
3. effect height, cost is low.The dichlorvos of the present invention mite aerosol of rattling away can need not converted water, thereby not rely on the water source yet with the direct dispenser of fog machine, not only saving of labor but also save time and go back water-saving, and effect is 10 times of conventional spraying, greatly reduces the dispenser cost.
4. little to environment and operating personnel's pollution and toxic hazard.Conventional atomized water spray endangers seriously operating personnel during to tall and big dense planting crop spraying, and soup runs off in a large number in soil, pollutes; And spray aerosol of the present invention, and the people carries on the back fog machine and walks the front against the wind, and ejection smog in back does not have influence to operating personnel; Smoke particle is atomic little, and anhydrous, and most medicines can paste obeys on crop, thereby very little to environmental influence.
5. save a large amount of fresh water.Conventional atomized water spray needs a large amount of valuable fresh water, and as dispenser in booth vegetable, every mu of ground need be converted more than the water 200Kg approximately; The spray aerosol then need not to convert water, does not rely on the water source, and every mu only need spray preparation 200-300 gram of the present invention and get final product.Therefore, can save a large amount of fresh water, especially more important to water-deficient areas such as mountain area, hills and arid are short of rain.
6. the advantage of the inventive method is need not special or special equipment, adopt known equipment to process, and technology is simple, and is with low cost.
