Description
Technical field
The invention belongs to the pesticide field that contains heterocyclic compound, be specifically related to a kind of Pesticidal combination and application thereof that clothianidin and pyridalyl be main active ingredient of take.
Background technology
Clothianidin (Clothianidin), chemical name: E)-1-(the chloro-1,3-thiazoles-5-of 2-ylmethyl)-3-methyl-2-nitroguanidine; Chemical molecular formula: C
6h
8clN
5o
2s; Sterling outward appearance is white crystals, 176.8 ℃ of fusing points, vapour pressure (20 ℃) 3.8 * 10-11Pa, solvability (g/L, 25 ℃): 0.327 (20 ℃) in water, in ethyl acetate 2.03, <0.00104 in normal heptane, in dimethylbenzene 0.0128, in carrene 1.32, in octanol 0.938, in acetone 15.2, in methyl alcohol 6.26.Structural formula:
Clothianidin acute oral toxicity, rat male and female: LD50 > 5000mg/kg, acute dermal toxicity: rat male and female: LD50 > 2000mg/kg, inhales people's toxicity: rat male and female, 6.1mg/L.
Clothianidin belongs to anabasine insecticide, be a kind of activity high, there is interior absorption, tag and the broad spectrum pesticide of stomach poison function.Shi Wu field company is after Nitenpyram (nitenpyram), and another nicotinic insecticide of discovery, belongs to the second generation.The mechanism of action is in conjunction with the nAChR that is positioned at neural post-synapse.Be applicable to foliar spray, soil treatment effect, show good quick-acting, the lasting period is about 7 days.Be mainly used in paddy rice, vegetables, fruit tree and other crop, control Semiptera, coleoptera, diptera and some lepidoptera pest.
Pyridalyl (Pyridalyl), has another name called fluoroform pyrrole ether, No. 1, wide side, the U.S. effect of speed, chemical name: 2-[3-[2, the chloro-4-[(3 of 6-bis-, the chloro-2-acrylic of 3-bis-) oxygen base] phenoxy group] propoxyl group]-5-(trifluoromethyl) pyrimidine, structural formula is:
Pyridalyl is the pesticide product that the sumitomo chemical company of Tokyo is developed, and it has and the diverse structure of existing insecticide, and the many lepidoptera pests on vegetables and cotton are had to remarkable insecticidal activity.Have simultaneously and tag and stomach poison function, contrary with its high activity, because pyridalyl is very little on various arthropodan impacts.Thereby fabulous protection target crop.Test shows with other insecticide without cross resistance.
Often there is defect in the insecticide variety containing single component: use is easily developed immunity to drugs continuously, and insecticidal spectrum is narrow, can not provide comprehensive protection for crop, and peasant's drug cost is high in agricultural chemicals control of insect.By two kinds or the coming year various active components be combined in to a certain extent the above-mentioned shortcoming of customer service to a certain extent.There is two kinds of synergistic effect or the combination of two or more active components and be mixed, can improve preventive effect, reduce active ingredient ground dosage, cost-saving, slow down pest resistance occur, and can expanding prevention spectrum, play that many worms are double to be controlled, reduce peasant's use cost.
Summary of the invention
The Synergistic insecticidal compositions that the object of this invention is to provide a kind of clothianidin-containing and pyridalyl, said composition can be used for preventing and treating various agricultural insect, for example, control vegetables diamond-back moth, cabbage caterpillar, can also, for preventing and treating cotton cotton bollworm, beet armyworm and Brown Planthopper etc., can reach the effect that a drug is prevented and treated dissimilar insect.
The Synergistic insecticidal compositions that another object of the present invention is to provide clothianidin-containing and pyridalyl is prevented and treated the application in the insecticidal materials of one or more insects in resistance Lepidoptera, Semiptera, Hymenoptera or coleoptera in preparation.
The present invention adopts following technical scheme:
A Synergistic insecticidal compositions for clothianidin-containing and pyridalyl, it take clothianidin and pyridalyl is main active ingredient, wherein, the weight ratio of clothianidin and pyridalyl is 0.1 ~ 80:0.5 ~ 80.Be preferably 1 ~ 60:1 ~ 70,1 ~ 30:1 ~ 30 more preferably, most preferably weight ratio is 1 ~ 10:1 ~ 10.This Synergistic insecticidal compositions can only contain active ingredient clothianidin and pyridalyl, also can when using or prepare, in active component, add other components, and the effective ingredient of above-mentioned potentiating pesticidal combination is present in composition with synergy effective dose.
At the Synergistic insecticidal compositions of clothianidin-containing of the present invention and pyridalyl, the two weight percentage in this Synergistic insecticidal compositions of clothianidin and pyridalyl is 2% ~ 80%, is preferably 8% ~ 60%, and optimum is 20% ~ 40%.
The Synergistic insecticidal compositions of above-mentioned clothianidin-containing and pyridalyl be take clothianidin and pyridalyl and is mixed with any one formulation allowing on agricultural chemicals as main active ingredient (active component) and insecticides adjuvant, excipients.The preferred pulvis of formulation, wetting powder, suspending agent, missible oil and water dispersion granule.
Aforementionedly can be applicable to the not special restriction of insecticides adjuvant of the present invention, include, but are not limited to calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33
#), polyoxyethylene nonylphenol ether etc., aforementionedly can be applicable to excipient of the present invention and be also not particularly limited, include, but are not limited to cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (as propane diols), deionized water etc.Above auxiliary agent, excipient and the upper known auxiliary material of other agricultural can alone or and use.
Application in the insecticidal materials of above-mentioned clothianidin-containing and the Synergistic insecticidal compositions of pyridalyl one or more insects in preparation control Lepidoptera, Semiptera, Hymenoptera or coleoptera.Especially the effect in the insecticidal materials of preparation control rice fulgorid or snout moth's larva is remarkable.
Synergistic insecticidal compositions antagonism lepidoptera pest of the present invention has significant preventive effect, especially for the easy various pests that produces resistance such as cotton cotton bollworm, beet armyworm, diamond-back moth, has good preventive effect; And suppress insect and the pesticide resistance of unitary agent (clothianidin or pyridalyl) is produced and can be prevented and treated simultaneously Semiptera insect as Brown Planthopper etc.
The insecticidal materials of being prepared by the Synergistic insecticidal compositions of described clothianidin-containing and pyridalyl is when preventing and treating resistance Lepidoptera, Hymenoptera or coleopteran pest, can prevent and treat Semiptera insect again, especially cotton cotton bollworm, diamond-back moth and beet armyworm are had to good preventive effect, reach the effect that a medicine is controlled more.
Pesticidal combination of the present invention compared with prior art, produces following beneficial effect: (1) is compared with single dose, and said composition insect has notable synergistic, has obviously improved control efficiency; (2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, reduce control recruitment cost; (3) alternative high-toxic pesticide, and significantly reduce field dosage, effectively reduce environmental pollution and residue of pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with clothianidin single dose, produce and use cost reduction; (6) suppressing insect strengthens the resistance of agricultural chemicals;
