Description

A kind of containing ethyl pleocidin and the Synergistic insecticidal compositions of MTMC and application

Technical field

The invention belongs to pesticide field, be specifically related to a kind of with ethyl pleocidin and the Synergistic insecticidal compositions of MTMC and should With.

Background technology

Ethyl pleocidin (Spinetoram), structural formula is:

XDE-175-J is the one produced by Dow AgroSciences novel pleocidin insecticides, and receives first whole world and step on Note, it can effectively control the important insect pest on fruit tree and nut, the especially a kind of thorny primary pest on fruit tree The stupid moth of apple.Be mainly used in preventing and treating lepidopterous larvae, thrips and Liriomyza etc., to diamondback moth, beet armyworm, Liriomyza, The prevention effect that thrips, prodenia litura, bean-pod borer have had.

MTMC (Metolcarb), chemical name: 3-tolyl-N-methyl carbamate, molecular formula: C9H11NO2, Structural formula:

MTMC has good tagging and fumigation action, and power of knocking down is strong, the lasting period 3~4d, rice leafhopper, planthopper is had speed Effect property prevention effect.

Insecticide variety containing single component often existing defects in agricultural chemicals control of insect: use is easily developed immunity to drugs continuously, Insecticidal spectrum is narrow, it is impossible to providing comprehensively protection for crop, peasant's drug cost is high.Become by the various activity of two kinds or the coming year The combination divided can overcome disadvantages mentioned above to a certain extent to a certain extent.There is two kinds or two or more work of synergistic effect Property composition combination mixture, can improve preventive effect, reduce active ingredient ground dosage, cost-effective, slow down pest resistance 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

It is an object of the invention to provide a kind of containing ethyl pleocidin with the Synergistic insecticidal compositions of MTMC, said composition can be used for Prevent and treat various agricultural insect, such as preventing and treating vegetables diamondback moth, cabbage caterpillar, it is also possible to be used for preventing and treating cotton boll worm, beet night Moth and Brown Planthopper etc., can reach a drug and prevent and treat the effect of dissimilar insect.

It is a further object of the present invention to provide the Synergistic insecticidal compositions containing ethyl pleocidin and MTMC and prevent and treat resistance squama in preparation Application in the insecticidal materials of one or more insects in wing mesh, Semiptera, Hymenoptera or coleoptera.

The present invention adopts the following technical scheme that

A kind of containing ethyl pleocidin with the Synergistic insecticidal compositions of MTMC, it is with ethyl pleocidin and MTMC for mainly having Effect composition, wherein, the weight ratio of ethyl pleocidin and MTMC is 0.1~80:0.5~80.It is preferably 1~9:1~12, enters One step is preferably 1:1~10.

Existing containing ethyl pleocidin and the Synergistic insecticidal compositions of MTMC, ethyl pleocidin and both MTMCs in the present invention Weight percentage in this Synergistic insecticidal compositions is 2%~80%, preferably 8%~60%, most preferably 20%~40%.

The above-mentioned Synergistic insecticidal compositions containing ethyl pleocidin and MTMC with ethyl pleocidin with MTMC for mainly effectively becoming (active component) and insecticides adjuvant, excipients is divided to be configured on agricultural chemicals any one formulation allowed.The preferred pulvis of formulation, can WP, suspending agent, missible oil and water dispersion granule.

Described auxiliary agent can use calcium dodecyl benzene sulfonate, APES, polyoxyethylene polyoxy propylene block altogether Polymers (such as agriculture breast 33#), NPE etc., excipient comprises cyclohexanone, dimethylbenzene, solvent naphtha, water, prevents Freeze agent (such as propane diols), deionized water etc..Above auxiliary agent, excipient and other agriculturally known auxiliary material can be alone or also With.

The above-mentioned Synergistic insecticidal compositions containing ethyl pleocidin and MTMC is at preparation preventing and treating Lepidoptera, Semiptera, Hymenoptera Or the application in the insecticidal materials of one or more insects in coleoptera.Especially at preparation preventing and treating planthopper or the insecticide of snout moth's larva Application effect in thing is notable.

The Synergistic insecticidal compositions antagonism lepidoptera pest of the present invention has significant preventive effect, particularly with cotton boll worm, beet Noctuid, diamondback moth etc. easily produce the various pests of resistance and have good preventive effect;And suppress insect to unitary agent (second Quito bacteriocidin or MTMC) the resistance to the action of a drug produce and simultaneously can prevent and treat Hemipteran pest such as Brown Planthopper etc..

The insecticidal materials prepared by the described Synergistic insecticidal compositions containing ethyl pleocidin and MTMC is preventing and treating resistance squama wing While mesh, Hymenoptera or coleopteran pest, Hemipteran pest can be prevented and treated again, especially to cotton boll worm, diamondback moth and beet Noctuid has good preventive effect, reaches the effect that a medicine is controlled more.

The 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, hence it is evident that improve prevention effect;(2) one medicines are controlled more, and a dispenser can prevent and treat various pests simultaneously, subtracts Preventing and treating recruitment cost less;(3) alternative high-toxic pesticide, and field dosage is greatly reduced, effectively reduce environmental pollution and agriculture Medicine remains;(4) have concurrently quick-acting and long-acting;(5) compared with ethyl pleocidin single dose, produce and use cost reduces;(6) The resistance of agricultural chemicals is strengthened by suppression insect.
