Abstract

The application relates to an insecticidal composition containing a pyrazole compound shown in a formula (I) and application thereof in controlling animal pests. The application also relates to a method for preventing and/or treating pest infestation in plants, plant propagation material and/or the surrounding environment by said insecticidal composition.

Description

Insecticidal composition containing pyrazole compound and use thereof Technical Field
The present application relates to an insecticidal composition containing a pyrazole compound represented by formula (I) and its use for controlling animal pests. The application also relates to a method for preventing and/or treating pest infestation in plants, plant propagation material and/or the surrounding environment by said insecticidal composition.
Background
Pyrazole compounds represented by the following formula (I) are described in patent document WO2012/143317A1 and are described as exhibiting excellent effects on various pests, particularly cowpea aphid, cotton leaf whitefly, rice planthopper, thrips, plutella xylostella, and the like. The activity of the material is good, but at low application levels there are sometimes disadvantages.
Chemical control is an important way of preventing or controlling pests in agriculture. But more and more pests of crops, fruits, vegetables, etc. have been reported to develop resistance in the world. Although alternative application of pesticides with different modes of action may be employed in good pest management practices, the method does not always have to achieve satisfactory pest control results.
In order to reduce or avoid adverse environmental or toxicological effects caused by the application of pesticides, it is desirable to provide a pesticidal composition comprising a pyrazole compound of formula (I) which is capable of providing an effective pest control effect while reducing the dosage rate of the active ingredient.
Disclosure of Invention
The application relates to an insecticidal composition, which comprises a component (A) and a component (B), wherein the component (A) is a pyrazole compound represented by a formula (I), and the component (B) is at least one compound selected from imidaclothiz, cycloxaprid, flupirfenidone, piprolin, ivermectin, pyriproxyfen, chlorantraniliprole, methoxyfenozide and lufenuron.
The insecticidal combinations for pest control that have been studied show that it is not easy to obtain a high synergistic control effect. Surprisingly, the pesticidal composition of the present application still exhibits a highly effective pest control effect at reduced application rates of component (a) and component (B) even in the case where component (a) and component (B) become completely ineffective at a low application rate range, and an unexpected synergistic effect is obtained.
The term "synergistic effect" as used herein refers to a synergistic effect obtained when two or more active compounds are combined, wherein the combined activity of the two or more active compounds exceeds the sum of the activities of the individual active compounds.
The presence of synergistic effects was determined using the method described in Colby s.r. "Calculating Synergistic and Antagonistic Responses of Herbicide Combinations," wells, 1967,15,20-22.

Detailed Description
Biological testing:
test example 1 test of thrips
Test subject: the cucumber thrips flavus is a 2-year-old nymph, and the tested thrips is collected from the new eastern farm cucumber population in the Jiangsu Kunshan Zhou Shi.
Test agent: the acetone used as the raw materials of the component (A) and the component (B) is prepared into mother liquor, and then the mother liquor is diluted to the required concentration by 0.1 percent of Tween-80 aqueous solution.
Cutting fresh and tender cowpea pod into pieces with length of about 2cm (two ends of the pod are flat, no holes are left for facilitating investigation of results), soaking in the medicinal liquid for 15s, and taking clear water (containing solvent and tween) as control. The treated pods are placed on water absorbing paper for natural airing, and are clamped into centrifuge tubes by small tweezers, wherein each tube is 1 section.
Sucking insects by adopting a self-made insect sucking device, and then flicking the test insects into the medicine tubes, wherein each tube is provided with 20 heads. All treatments were placed in a light incubator at 25℃and 12H/12H for cultivation, and after 72 hours the number of live insects was investigated and the rate of reduction of the insect population and the control effect were calculated. Each treatment was repeated 4 times.
The calculation method comprises the following steps:
rate of reduction of insect population (%) = (number of live insects before drug-number of live insects after drug)/number of live insects before drug x 100
Control% = ((treatment group rate of reduction of insect population-control group rate of reduction of insect population)/(100-control group rate of reduction of insect population)) ×100
TABLE 1 control of thrips by combination of Compounds of formula I and component (B)
Test example 2 Activity against Aphis mairei
The active ingredient is applied as a dry seed dressing. By mixing the individual active compounds or the combination of active compounds with finely divided minerals, a finely divided composition is obtained which is homogeneously distributed over the seed surface.
When the seeds are mixed, each medicament is firstly mixed into slurry according to the designed dosage, then the seeds and the liquid medicine are shaken for 3 minutes in a closed glass flask, and after the seeds are uniformly mixed, the seeds are poured out, spread out and placed in a ventilation place, and are sown after being dried in the air.
The test soil and sand were of the same origin and were not subjected to any pesticide treatment. 60 wheat seeds were treated each, 3 replicates of 20 each. All treated flowerpots were placed in a controlled sunlight greenhouse at 15 ℃. And observing the growth condition of crops. Each pot is planted into 15 wheat plants after seedling emergence. On the 7 th day after emergence, 10 wheat binary aphids were inoculated per pot. And 5 days after insect inoculation, counting living aphids, and calculating the rate of reduction of insect population and the prevention effect.
The calculation method comprises the following steps:
rate of reduction of insect population (%) = (number of live insects before drug-number of live insects after drug)/number of live insects before drug x 100
Control% = ((treatment group rate of reduction of insect population-control group rate of reduction of insect population)/(100-control group rate of reduction of insect population)) ×100
TABLE 2 Activity of combinations of Compounds of formula I and component (B) against Aphis mairei
Tables 1 and 2 show that the pesticidal compositions of the present application exhibit excellent and synergistic properties in controlling and treating pest attack.
