Description
Technical field
The invention belongs to the pesticide field containing heterocyclic compound, be specifically related to a kind of be principle active component Pesticidal combination and the application thereof of clothianidin and chlorfluazuron.
Background technology
Clothianidin (Clothianidin), chemical name: E)-1-(the chloro-1,3-thiazoles of 2--5-ylmethyl)-3-methyl-2-nitroguanidine; Chemical molecular formula: C
6h
8clN
5o
2s; Sterling outward appearance is white crystals, fusing point 176.8 DEG C, vapour pressure (20 DEG C) 3.8 × 10-11Pa, solvability (g/L, 25 DEG C): 0.327 (20 DEG C) 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 combines the nAChR being positioned at neural post-synapse.Be applicable to foliar spray, soil treatment effect, show good quick-acting, the lasting period was at about 7 days.Be mainly used in paddy rice, vegetables, fruit tree and other crop, control Semiptera, coleoptera, diptera and some lepidoptera pest.
Chlorfluazuron (Chlorfluazuron), chemical name: 1-(the chloro-4-of 3,5-bis-(the chloro-5-trifluoromethyl of 3--2-pyridine oxygen base) phenyl)-3-(2,6-difluoro benzoyl) urea, structural formula is:
Chlorfluazuron is a kind of widely used growth regulator, tool stomach toxicity, action of contace poison.The mechanism of action suppresses chitin synthesis, and hinder insect normally to cast off a skin, make the developmental deformity of the hatching of ovum, larval molting and pupa, adult eclosion is obstructed.Drug effect is high, and speed of action is comparatively slow, and to multiple lepidoptera pest, and orthoptera, coleoptera, Hymenoptera, diptera isoreactivity are high, but invalid to aphid, leafhopper, plant hopper.Chlorfluazuron is to mammiferous acute through skin LD
50>8500mg/kg, acute oral LD
50>1000mg/kg.
Containing the insecticide variety of single component often existing defects in agricultural chemicals control of insect: use is easily developed immunity to drugs continuously, and insecticidal spectrum is narrow, and can not provide comprehensive protection for crop, peasant's drug cost is high.By two kinds or the coming year various active component be combined in a certain extent can the above-mentioned shortcoming of customer service to a certain extent.There is two kinds of synergistic effect or the combination mixture of two or more active component, can insecticidal spectrum be expanded, improve preventive effect, reduce active ingredient ground dosage, cost-saving, slow down pest resistance and occur and can expanding prevention compose, play that many worms are double to be controlled, reduce the use cost of peasant.
Summary of the invention
The object of this invention is to provide the Synergistic insecticidal compositions of a kind of clothianidin-containing and chlorfluazuron, said composition can be used for preventing and treating various agricultural insect, such as can also prevent and treat the lepidoptera pest such as diamond-back moth, beet armyworm while control vegetable aphid and thrips etc., the effect that a drug prevents and treats dissimilar insect can be reached.
The Synergistic insecticidal compositions that another object of the present invention is to provide clothianidin-containing and chlorfluazuron is preparing the application prevented and treated in the insecticidal materials of one or more insects in resistance Lepidoptera, Semiptera, Hymenoptera or coleoptera.
The present invention adopts following technical scheme:
A Synergistic insecticidal compositions for clothianidin-containing and chlorfluazuron, it is with clothianidin and chlorfluazuron for principle active component, and wherein, the weight ratio of clothianidin and chlorfluazuron is 1 ~ 80:1 ~ 80.Be preferably 1 ~ 60:1 ~ 70, more preferably 1 ~ 30:1 ~ 30, most preferably weight ratio is 1 ~ 10:1 ~ 10.This Synergistic insecticidal compositions can only containing active ingredient clothianidin and chlorfluazuron, and also can add other components when using or prepare in active component, the effective ingredient of above-mentioned Insecticidal combinations is present in composition with enhancing effective amount.
At the Synergistic insecticidal compositions of clothianidin-containing of the present invention and chlorfluazuron, both clothianidin and the chlorfluazuron weight percentage in this Synergistic insecticidal compositions is 2% ~ 80%, and be preferably 8% ~ 60%, optimum is 20% ~ 40%." % " of the present invention is mass percent.
The Synergistic insecticidal compositions of above-mentioned clothianidin-containing and chlorfluazuron with clothianidin and chlorfluazuron for principle active component (active component) and insecticides adjuvant, excipients are mixed with any one formulation that agricultural chemicals allows.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 other agriculturally known auxiliary material can be alone or and use.
Application in the insecticidal materials of above-mentioned clothianidin-containing and the Synergistic insecticidal compositions of chlorfluazuron one or more insects in preparation control Lepidoptera, Semiptera, Hymenoptera or coleoptera.Especially the effect in preparation control cotton bollworm or diamond-back moth insecticidal materials is remarkable.
Synergistic insecticidal compositions antagonism lepidoptera pest of the present invention has significant preventive effect, especially has good preventive effect for the easy various pests producing resistance such as cotton bollworm, diamond-back moth, thrips; And suppress insect produce the pesticide resistance of unitary agent (clothianidin or chlorfluazuron) and Hemipteran pest can be prevented and treated as aphid, aleyrodid, leafhopper etc. simultaneously.
The insecticidal materials prepared by the Synergistic insecticidal compositions of described clothianidin-containing and chlorfluazuron is while preventing and treating resistance Lepidoptera, Hymenoptera or coleopteran pest, Hemipteran pest can be prevented and treated again, there is good preventive effect to vegetables diamond-back moth, leafhopper, aleyrodid and aphid especially, reach the effect that a medicine is controlled more.
Pesticidal combination of the present invention compared with prior art, produces following beneficial effect: (1), compared with single dose, said composition insect has notable synergistic, significantly improves 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) compared with clothianidin single dose, produce and use cost reduction; (6) insect is suppressed to strengthen the resistance of agricultural chemicals;
