Abstract
The invention relates to a method for preparing crop combined insecticide micellar emulsion from thiocyclam and fipronil. The method comprises diluting 90% thiocyclam with clean water to 20-50%, mixing the diluted thiocyclam with anionic emulsifier containing phenylacetaldehyde polyoxyethylene ether, solvent naphtha and 5% fipronil suspension at a wt. ratio of 1:0.0005-0.002:0.02-0.5:0.1-0.3, and stirring. The invention has improved thiocyclam utilization ratio and effect due to the use of anionic emulsifier containing phenylacetaldehyde polyoxyethylene ether which increases the adhesion and permeability of micellar emulsion on crop, and use of fipronil suspension which increases kills knockdown force to pest and reduces fastness of pest against thiocyclam.
Description
Technical field
The present invention relates to a kind of preparation method of crops pesticide, particularly a kind of method for preparing thiocyclam and fipronil composite micro emulsion.
Background technology
Snout moth's larva is an insect pest of rice, belongs to phosphorus wing order.Mainly contain three kinds of striped rice borer, paddy stem borer and leaf-rollers at Dao Qu, the district all has in various degree and takes place throughout the country.
Thiocyclam (chemical name: N, N-dimethyl-1,2,3-three thias oneself-5-amine, English common name: thiocyclam) nereistoxin insecticide, tool are tagged, stomach poison function, have to inhale conduction and ovum performance is extremely arranged in certain.This product is imitated slowly insect is plain, and the longevity of residure is short, and Lepidoptera, coleoptera are had good control efficiency.
Sharp strength spy (chemical name: 5-amino-3-cyano group-1-(2; 6-dichlor-4-trifluoromethyl phenyl)-the 4-trifluoromethyl sulfinyl pyrazole; English common name: fipronil); fluorine-containing pyrazoles broad spectrum insecticide; active high; applied range has produced resistant insect and has also shown high susceptibility insects such as Semiptera, thrips, sheath, Lepidoptera and chrysanthemum ester class, amino-acid ester insecticides.
The synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, up to now, still finds no the report that closes thiocyclam and fipronil composite micro emulsion.
Purpose of the present invention just provides a kind of thiocyclam and fipronil Recompounded pesticide, and the expanding prevention spectrum improves drug effect, reduces resistance, reduces the agricultural chemicals usage amount, reduces cost, and reduces environmental pollution.
Summary of the invention
Method for preparing thiocyclam and fipronil composite micro emulsion, mainly be with water miscible thiocyclam and the special two kinds of insecticides of oil-soluble sharp strength through being processed into composite micro emulsion, contain thiocyclam 10-30%, the special 0.6-1% of sharp strength in its composite micro emulsion.
The technology of the present invention solution:
A kind of preparation method of thiocyclam and fipronil composite micro emulsion, it is characterized in that the thiocyclam with 90% dilutes with clear water, its concentration is controlled at 20-50%, with the thiocyclam after the dilution with after anion emulsifier phenylacetaldehyde APEO and solvent naphtha mix, add the special suspending agent of 5% sharp strength, stir and promptly get composite micro emulsion of the present invention.Its proportioning is: dilution thiocyclam: emulsifier: solvent naphtha: the special suspending agent of 5% sharp strength=1: 0.0005 0.002: 0.02-0.5: 0.1-0.3 (volume ratio).The present invention since increased contain phenylacetaldehyde APEO anion emulsifier after, increased adhesive force and the penetration of this microemulsion on crops greatly, and having increased the special suspending agent of 5% sharp strength in microemulsion has increased the power of knocking down of insect and has reduced the resistance of insect to thiocyclam, thereby has strengthened the availability and the effect of thiocyclam.
Advantage of the present invention and beneficial effect
(1), quick-acting, high efficiency: the result by repetition test shows, compounded pesticides 100ml/ mu of the present invention, preventive effect to the withered heart reached 96.8% than singly high by 21% with 50% thiocyclam, 50 gram/mus in 24 hours, it is single high by 23% with 50% thiocyclam, 50 gram/mus that the preventive effect of withered sheath reaches 95.3% ratio, demonstrates quick-acting preferably and high efficiency; (2), the mechanism of action difference, compound synergic is remarkable, and is many to the insect action site, by the composite pest killing micro emulsion that forms of the present invention, has higher compound synergic effect, the preparation stable performance; (3), insecticidal spectrum is wide: the microemulsion that the present invention is formulated, the insecticidal action spectrum is wide, can prevent and treat multiple different insects purpose insect.
