Description

Insecticidal composition containing alkylphenyl sulfide derivative and application thereof Technical Field
The present application relates to insecticidal compositions containing alkylphenyl sulfide derivatives and to their use for controlling animal pests. The application also relates to a method for preventing and/or treating pest infections in plants, plant parts and/or the surrounding environment by means of said pesticidal composition.
Background
Pest infection is a major threat to important commercial crops such as soybean and cotton. Crop yield is negatively affected by pest infestation. Chemical control is an important way to prevent and control pests in agriculture. However, but as indicated by experience worldwide with single active pesticide direct formulations, there is a high risk of creating resistant pest subpopulations. More and more pests of crops, fruits, vegetables, etc. have been reported to develop resistance in the world. In addition, there is an increasing environmental and economic demand for pesticides (e.g. in terms of spectrum of action, toxicity, selectivity, rate of application, formation of residues and good preparation ability).
An alkylphenyl sulfide derivative represented by the following formula (I) is described in patent document WO2013157229A1, and is described as exhibiting excellent effects against various pests, particularly against spider mites typified by spider mites, and the like. The activity of the material is good, but at low application levels there are sometimes disadvantages.
Disclosure of Invention
The application relates to an insecticidal composition comprising components (A) and (B), wherein the component (A) is a compound of formula I selected from alkyl phenyl thioether derivatives, and the component (B) is at least one compound selected from abamectin, diafenthiuron and lufenuron.
The insecticidal composition of the present application may preferably comprise a combination of the following components:
(A) A compound of formula I and (B) abamectin;
(A) A compound of formula I and (B) diafenthiuron; and

Particularly remarkable improvement effect is exhibited when the components (a) and (B) are present in a specific weight ratio. In particular, the weight ratio of components (a) and (B) in the compositions of the present application is preferably from about 50:1 to about 1:50, more preferably from about 25:1 to about 1:25, or from about 15:1 to about 1:15 or from about 10:1 to about 1:10.
In general, the active ingredient combinations according to the application comprise (A) compounds of the formula I and (B) mixed counterparts in the preferred and particularly preferred mixing ratios given in the tables below.
Component (B) Preferred mixing ratio More preferred mixing ratio Particularly preferred mixing ratios
Avermectins 25:1 to 1:25 10:1 to 1:1 5:1 to 1:1
Diafenthiuron 50:1 to 1:50 10:1 to 1:40 1:1 to 1:20
Lufenuron (lufenuron) 10:1 to 1:10 5:1 to 1:5 2:1 to 1:2
* The mixing ratio is based on the weight ratio. The ratio is understood to be the formula component (A) and component (B).

In the test, the withered and yellow leaves and redundant tillers (2-3 effective tillers are reserved in each pot) are removed, the upper part is cut off, the plant with the length of 20-25 cm is left, the plant is immersed into the prepared liquid medicine for 10s, and the liquid medicine on the surface of the dried rice plant is taken out and then inoculated with insects. Selecting low-age (2-3-age) nymphs, and inoculating 20 homonymphs into each pot of seedlings. The rear cover is provided with a plastic cage with air holes. Each treatment was repeated 4 times with 1 repetition per pot. All experiments were carried out in a sunlight greenhouse (natural light) with a temperature of 27 ℃ ± 1 ℃ and a humidity of 75% ± 5%. After 4d, the number of living insects in each pot of seedlings is observed and recorded, and the insecticidal activity of each medicament treatment is evaluated. The clear water containing solvent and emulsifier is used as control.
The live worm reduction rate and the prevention and treatment effect of each treatment are calculated according to the following formula:
the rate of reduction of live insects (%) = (number of live insects before administration-number of live insects after administration)/number of live insects before administration ×100
Control effect (%) = (agent treatment area live worm reduction rate-control area live worm reduction rate)/(100-control area live worm reduction rate) ×100
In addition, the theoretical control effect (%) can be calculated by the Colby formula. When the actual control effect (%) is higher than the theoretical control effect (%), the composition of the present application has a synergistic effect.

EXAMPLE B citrus rust mite test (resistance)
The raw materials of the compound of the formula (I), diafenthiuron, lufenuron and abamectin are respectively dissolved by a solvent to prepare a single-dose mother solution, and then the single-dose mother solution is diluted to the required concentration by an aqueous solution containing 0.1% of Tween-80.
The rust mites to be tested are female adult mites with consistent size and health and liveness. The leaf is healthy, complete and uniform. The citrus leaves were punched with a punch to form leaf discs with a leaf diameter of 2 cm. Placing wet sponge block in the culture dish, placing filter paper thereon, and placing leaf butterfly on the filter paper for use. And (5) inoculating the citrus rust mites into the mites to form mites. 20 female adult mites were inoculated on each leaf disk.
Treatment was carried out using a POTTER spray tower. The amount of spray per treatment was 2mL. After the treatment, the citrus leaves are placed in a thermostatic chamber at a temperature of (25+/-1) DEGC and a relative humidity of (70+/-10)%, and the illumination ratio L: D is 16:8 for cultivation. Each treatment was repeated 3 times. Death of adult mites was observed after 2 days. The non-respondent was treated as dead by touching the spider mite's foot and mouth with a small writing brush tip. The clear water containing solvent and emulsifier is used as control.
The live mite reduction rate and the control effect of each treatment are calculated according to the following formula:
live mite reduction rate (%) = (number of live mites before administration-number of live mites after administration)/number of live mites before administration 100
Control effect (%) = (agent treatment area live mite reduction rate-control area live mite reduction rate)/(100-control area live mite reduction rate) ×100
In addition, the theoretical control effect (%) can be calculated by the Colby formula. When the actual control effect (%) is higher than the theoretical control effect (%), the composition of the present application has a synergistic effect.
TABLE 2
It is apparent from tables 1-2 that the combination of the compound of formula (I) with abamectin, diafenthiuron or lufenuron significantly enhances pest control beyond the predictions of those skilled in the art.
