Abstract
The present invention relates to a wide-spectrum pesticide comprising the following raw materials: 7 to 13 percent of quinalphos, 3 to 9 percent of carbosulfan, 2 to 4 percent of an emulsifying agent 0204C, 0.5 to 1.5 percent of an emulsifying agent 2201, 0.3 to 0.7 percent of ethyl acetate as stabilizer and the rest amount of solvent. The pesticide in the formulation of emulsifiable solution has the advantages of stable effect of the pesticide, long storage period, low toxicity and no nuisance; the wide-spectrum pesticide can be used for controlling various destructive insects, and particularly, the wide-spectrum pesticide has specially good effect to the destructive insect difficult to control at present, such as pine wood nematode, monochamus alternatus, etc.
Description
The invention belongs to a kind of wide spectrum agricultural chemicals that can prevent and treat various pests, evil mite.
Pine wood nematode is one of 5 kinds of forest disease and pests of present China generation area maximum and harmfulness maximum, and this insect can cause the large tracts of land pine forest withered, and Monochamus alternatus then is its communications media, and these two kinds of insects are not also had special efficacy control agricultural chemicals now.981133568 patent applications disclose a kind of insecticide that is mixed with quinalphos and carbosulfan, some insects that can tag and comprise above-mentioned two kinds of insects, but the mixed ratio of undeclared two kinds of single agent, particularly owing to do not have effective auxiliary element-stabilizing agent, emulsifier and solvent to cooperate, so soup is layering and precipitating very easily, can't in practical operation, give full play to its drug effect, also not reach country simultaneously the minimum basic demand that will reach 2 years of agricultural chemicals storage life.
The present invention aims to provide a kind ofly has strong lethality to various pests such as pine wood nematode, Monochamus alternatus, litchi and longan tea material bark beetle, evil mite, and the wide spectrum mixed insecticide of efficacy stability, long shelf-life.
The technical scheme that realizes above-mentioned purpose is: the present invention is the missible oil formulation, and its primary raw material quality proportioning is as follows:
Quinalphos: 7～13% (empirical formulas: C
12H
15N
2O
3PS)
Carbosulfan: 3～9% (empirical formulas: C
20H
32N
2O
3S)
Emulsifier: 0204C:2～4%
Emulsifier: 2201:0.5～1.5%
Stabilizing agent ethyl acetate: 0.3～0.7%
Surplus is a solvent, and described solvent can be a dimethylbenzene, or toluene, or benzene.
In the above-mentioned missible oil that is mixed, also can add an amount of bleeding agent and antifreeze.
Preparation method of the present invention is: elder generation drops into half of required solvent according to the above ratio at normal temperatures, drops into other raw material while stirring, and then drops into second half solvent, is stirred to the homogeneous phase oily liquids.Also all raw materials can be dropped into container simultaneously, stir, directly be stirred to the homogeneous phase oily liquids while throwing.
General using method of the present invention is: with missible oil thin up to 500 times, spray application to plant branch, do, on the blade face, approximately through 3～15 days, insect, evil mite and larva children ovum are killed successively with compression sprayer, reach and prevent and treat purpose.The serious insect of the antagonism property of medicine then is diluted to 200～300 times of uses.
Through the pesticide toxicology test, the present invention is medium malicious agricultural chemicals.
The present invention is a kind of broad-spectrum high efficacy agricultural chemicals that can prevent and treat tens of kinds of insects such as trunk borer on forest, grain, the economic crops, riceization snout moth's larva, cotton bollworm, cotten aphid, vegetables diamond-back moth, evil mite, control efficiency to most insects can reach more than 96%, particularly to the pine wood nematode in the trunk borer, Monochamus alternatus, some insects that are difficult at present prevent and treat such as longan lichee tea material folliculus have special efficacy.Contained auxiliary element emulsifier, stabilizing agent, the solvent of this agricultural chemicals can make soup be the homogeneous phase oily, not stratified during placement, do not precipitate, assurance active ingredient is not degraded, thereby keep the stable of drug effect, can reach its storage period more than 2 years, this toxicity of pesticide is low, nuisanceless simultaneously, it is residual, safe in utilization not have accumulation and persistence in vivo.
Embodiment 1
The raw material mass mixture ratio that this example adopted is (with 100 kilograms of calculating):
Quinalphos (folding hundred): 10% carbosulfan (folding hundred): 6%
0204C： 3％ 2201： 1％
Ethyl acetate: 0.5% dimethylbenzene: supply 100%
Above-mentioned quinalphos, carbosulfan material concentration less than 100% is all in effective mass.
At normal temperatures, will make an appointment with half xylene solvent to drop into container earlier, and drop into other raw material while stirring, adding all the other dimethylbenzene to total amount again is 100 kilograms, is stirred to be the homogeneous phase oily liquids.
After being processed into, this example is the light brown homogeneous liquid; Method by GB/T1601 detects, and pH value is 7.5; With the stability of GB/T1603 method test emulsion, on do not have under the oil slick and not have precipitation; Its low-temperature stability and heat storage stability are combined country to the requirement of Pesticidal products in addition.
300 times of this medicine dilutions are used to prevent and treat the pine nematode tree, the disease tree that sprays this medicine reduces 63% than the sick tree of the contrast of not spraying medicine dead and drying tree, not withered disease tree is not found the illness diffusion, plant still grows normally, and the disease of control group tree is basic all dead, illustrates that this medicine has obvious inhibition effect to pine wood nematode.
Be used to prevent and treat the medium Monochamus alternatus of pine wood nematode, its insecticidal effect reaches more than 96%, the highest can be near 100%.
Above-mentioned test illustrates that this medicine is to prevent and treat the specificity insecticide that pine nematode and Monochamus alternatus have dual usefulness at present.
In addition, be used to prevent and treat litchi and longan tea material bark beetle, preventive effect can reach 96.5% (preferably can only reach 70～80% with existing agricultural chemicals).Be used to prevent and treat Opogona sacchari, preventive effect can reach more than 90%, obviously is better than existing organophosphorous pesticide.
Embodiment 2～5 explanation: every example is all with 100 kilograms of calculating, and its quality proportioning is raw material embodiment 2 embodiment 3 embodiment 4 embodiment 5 quinalphos (folding hundred) 7% 9% 11% 13% carbosulfans (folding hundred) 3% 4% 7% 9% emulsifying agent 0204C 2% 2.5% 3.5% 4% emulsifying agents 2,201 0.5% 0.8% 1.2% 1.5% ethyl acetate 0.3% 0.4% 0.6% 0.7% solution toluene benzene xylene xylenes
Supplying 100% supplies 100% and supplies 100% and supply 100%
Embodiment 2～5 all can realize the object of the invention.Embodiment 1 is a most preferred embodiment.
If in mixed emulsifiable solution of the present invention, add an amount of bleeding agent, also can improve the permeability of soup, further strengthen its lethality to insect evil mite, add an amount of antifreeze, can improve its low-temperature stability.
