Description

Insecticidal compositions containing alkylphenyl sulfide derivatives and uses thereof technical field

The present application relates to pesticidal compositions containing alkylphenyl sulfide derivatives and their use for controlling animal pests. The present application also relates to methods for preventing and/or treating pest infestations in plants, plant parts and/or the surrounding environment with said pesticidal composition.

Background technique

Pest infestation is a major threat to commercially important crops such as soybeans and cotton. Crop yields are negatively affected by pest infestation. Chemical control is an important way to prevent and control pests in agriculture. However, world experience with direct formulations of insecticides with single activity points to a high risk of developing resistant subpopulations of pests. It has been reported that more and more crops, fruits, vegetables and other pests have developed resistance in the world. In addition, the environmental and economic requirements placed on pesticides (for example with regard to spectrum of action, toxicity, selectivity, application rates, formation of residues and good preparation capabilities) are currently constantly increasing.

The alkylphenyl sulfide derivative represented by the following formula (I) is described in the patent document WO2013157229A1, and it is recorded that it is effective against various harmful organisms, especially against Tetranychus urticae, Tetranychus kamizawa, Tetranychus represented by Panonychus and the like show excellent effects. The activity of this substance is very good, but sometimes still insufficient at low application rates.

Biological test:

Embodiment A brown planthopper test

Dissolve the compound of formula (I) and the original drug of avermectin in a solvent to prepare a single-dose mother solution, and then dilute to the required concentration with an aqueous solution containing 0.1% Tween-80.

The experiment was carried out by rice seedling dipping method. The rice seedlings for the test were insect-free TN1 seedlings at the peak tillering stage, transplanted in small mud pots one week before the test, placed in an insect-free environment, and washed after the rice seedlings survived for later use. During the test, remove the withered yellow leaves and redundant tillers (leave 2 to 3 effective tillers in each pot), cut off the upper part, leave a 20-25 cm plant, immerse in the prepared medicinal solution for 10 seconds, take out the medicinal solution on the surface of the rice plant and dry it. Infestation. Select young (2-3 instar) nymphs, and insert 20 nymphs of the same stage into each pot of seedlings. There is a plastic cover with ventilation holes on the cover after picking up the worms. Each treatment was repeated 4 times, and each pot was 1 repetition. All tests were carried out under the conditions of a sunny greenhouse (natural light) with a temperature of 27°C±1°C and a humidity of 75%±5%. After 4 days, observe and record the number of live insects in each pot of seedlings, and evaluate the insecticidal activity of each chemical treatment. Water containing solvents and emulsifiers was used as a control.

The live insect reduction rate and control effect of each treatment were calculated according to the following formula:

Reduction rate of live insects (%) = (number of live insects before application - number of live insects after application) / number of live insects before application * 100

Control effect (%) = (reduction rate of live insects in chemical treatment area - reduction rate of live insects in control area) / (100 - reduction rate of live insects in control area) * 100

In addition, the theoretical control effect (%) can be calculated by Colby's formula. When the actual control effect (%) is higher than the theoretical control effect (%), the composition of the present application has a synergistic effect.

Table 1

*Measured value = measured activity

** Calculated value = activity calculated using Colby's formula

Embodiment B citrus rust mite test (resistance)

Dissolve the original drugs of the compound of formula (I), diafenthiuron, lufenuron and avermectin in a solvent to prepare a single-dose mother solution, and then dilute to the required concentration with an aqueous solution containing 0.1% Tween-80.

For the rust mites to be tested, healthy and active adult females of the same size were selected. The tested leaves were healthy, complete and uniform citrus. The citrus leaves are punched into leaf disks with a leaf diameter of 2 cm with a punch. Place the wet sponge block in the petri dish, put the filter paper on it, put the leaf butterfly on the filter paper, set aside. Access citrus rust mite adult mites. Each leaf disc was inoculated with 20 female adult mites.

Use POTTER spray tower for treatment. The spray volume of each treatment is 2mL. After the treatment, the citrus leaves were cultured in a constant temperature room with a temperature of (25±1)°C, a relative humidity of (70±10)%, and a light ratio L:D of 16:8. Each treatment was repeated 3 times. After 2 days, the death of adult mites was observed. Touch the feet and mouthparts of the spider mite with the tip of a small brush, and those who do not respond are considered dead. Water containing solvents and emulsifiers was used as a control.

The live mite reduction rate and control effect of each treatment were calculated according to the following formula:

Reduction rate of live mites (%) = (number of live mites before application - number of live mites after application) / number of live mites before application * 100

Control effect (%) = (the reduction rate of live mites in the chemical treatment area - the reduction rate of live mites in the control area) / (100 - the reduction rate of live mites in the control area) * 100

In addition, the theoretical control effect (%) can be calculated by Colby's 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 can be clearly seen from Table 1-Table 2 that the combination of the compound of formula (I) and avermectin, diafenthiuron or lufenuron significantly enhanced the pest control effect, beyond the prediction of those skilled in the art.
