Description

A kind of Pesticidal combination and application thereof containing ethyl pleocidin and spiral shell worm ethyl ester
Technical field
The invention belongs to pesticide field, be specifically related to a kind of be principle active component Pesticidal combination and the application thereof of ethyl pleocidin and spiral shell worm ethyl ester.
Background technology
Ethyl pleocidin (Spinetoram), structural formula is:
XDE-175-J is the novel pleocidin insecticides of one of being produced by Dow AgroSciences, and receive first whole world registration, it effectively can control the important insect pest on fruit tree and nut, a kind of thorny primary pest especially on fruit tree---the stupid moth of apple.Be mainly used in control lepidopterous larvae, thrips and Liriomyza etc., to the control efficiency that diamond-back moth, beet armyworm, Liriomyza, thrips, prodenia litura, lima bean pod borer have had.
Spiral shell worm ethyl ester (Spirotetramat) chemical name is: 4-(ethoxy carbonyl oxygen base)-8-methoxyl group-3-(2,5-xylyl)-1-azaspiro [4, the 5]-last of the ten Heavenly stems-3-alkene-2-ketone.Structural formula is as follows:
Spiral shell worm ethyl ester high-efficiency broad spectrum, can effectively prevent and treat various sucking pest, as aphid, thrips, wood louse, mealybug, aleyrodid and scale insect etc.Applicable chief crop comprises, cotton, soybean, oranges and tangerines, tropical fruit tree, nut, grape, lupulus, potato and vegetables etc.Research shows it to important beneficial insect as ladybug, syrphus fly and parasitic wasp have good selectivity.
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.Being combined in and can overcoming above-mentioned shortcoming to a certain extent to a certain extent by two kinds or various active component in the coming year.There is two kinds of synergistic effect or the combination mixture of two or more active component, can preventive effect be improved, reduce active ingredient ground dosage, cost-saving, slow down pest resistance and to occur and can expanding prevention spectrum, 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 a kind of Pesticidal combination containing ethyl pleocidin and spiral shell worm ethyl ester, said composition can be used for preventing and treating various agricultural insect, such as control vegetables diamond-back moth, cabbage caterpillar, can also be used for preventing and treating cotton cotton bollworm, beet armyworm and Brown Planthopper etc., the effect that a drug prevents and treats dissimilar insect can be reached.
The Pesticidal combination that another object of the present invention is to provide containing ethyl pleocidin and spiral shell worm ethyl ester 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 kind of Pesticidal combination containing ethyl pleocidin and spiral shell worm ethyl ester, it is with ethyl pleocidin and spiral shell worm ethyl ester for principle active component, and wherein, the weight ratio of ethyl pleocidin and spiral shell worm ethyl ester is 0.1 ~ 80:0.5 ~ 80, be preferably 1 ~ 9:1 ~ 12, more preferably 1:1 ~ 10.
At the Pesticidal combination containing ethyl pleocidin and spiral shell worm ethyl ester of the present invention, ethyl pleocidin is 2% ~ 80% with the weight percentage both spiral shell worm ethyl ester in this Pesticidal combination, preferably 8% ~ 60%, most preferably be 20% ~ 40%.
The above-mentioned Pesticidal combination containing ethyl pleocidin and spiral shell worm ethyl ester with ethyl pleocidin and spiral shell worm ethyl ester 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.
Described auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, the rare block copolymer of polyoxyethylene polyoxy third (as agriculture breast 33#), polyoxyethylene nonylphenol ether etc., and excipient comprises 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.
The present invention is preparing the application in the insecticidal materials preventing and treating one or more insects in Lepidoptera, Semiptera, Hymenoptera or coleoptera containing the Pesticidal combination of ethyl pleocidin and spiral shell worm ethyl ester.Especially the effect in the insecticidal materials preparing control rice fulgorid or snout moth's larva is remarkable.
Pesticidal combination 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 cotton bollworm, beet armyworm, diamond-back moth; And suppress insect produce the pesticide resistance of unitary agent (ethyl pleocidin or spiral shell worm ethyl ester) and Hemipteran pest can be prevented and treated as Brown Planthopper etc. simultaneously.
The insecticidal materials prepared by the described Pesticidal combination containing ethyl pleocidin and spiral shell worm ethyl ester 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 cotton cotton bollworm, diamond-back moth and beet armyworm 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 ethyl pleocidin single dose, produce and use cost reduction; (6) insect is suppressed to strengthen the resistance of agricultural chemicals.
