Embodiment 1

[0055] Biological Assay Example 1: Combined Effect Assay.

[0056] Referring to NY / T 1154.6-2006, the insecticidal activity of the pesticide was determined by the method of soaking insects. Slightly anesthetize the target insects with ether, wrap them in gauze, soak them in the liquid to be tested for 5-10 seconds, take them out, wipe off the excess liquid with filter paper, transfer the insects to a petri dish, and remove the dead ones. worms, put fresh eggplant leaves for normal cultivation. Each treatment was repeated 4 times, with 30 test insects in each repetition, and the treatment of the corresponding organic solvent without medicament was used as the control.

[0057] Based on the survey data, the mortality rate and adjusted mortality rate (%) for each treatment were calculated.

[0058]

[0059] In the formula: P 1 Indicates the mortality rate; K indicates the number of dead test insects; N indicates the total number of test insects investigated.

Embodiment 2

[0093] Bioassay Example 2: Field Trial of Controlling Thrips in Eggplant.

[0094] The test site is located in an eggplant field in Yanglin New Village, Songming County, Kunming City, Yunnan Province, with 50% insecticidal SP and 5% pyriproxyfen ME as control drugs. There are 13 drug treatments in the test, and each treatment is repeated 4 times. 3 days and 10 days after spraying, investigate and record the insect population base, and calculate the control effect. The test results are shown in Table 5.

[0096]

[0097] As can be seen from Table 5, the control effect of the insecticidal composition of the present invention is better than that of each control single-dose treatment, indicating that the compounding of insecticidal cyclocyclone and pyriproxyfen can effectively control eggplant thrips, and the duration of effect is better than that o...

Embodiment 3

[0098] Biological Assay Example 3: Field Test of Controlling Eggplant Whitefly.

[0099] The test site is located in Shizhen Village, Zhongkai High-tech Zone, Huizhou City, Guangdong Province. 50% insecticidal SP and 5% pyriproxyfen ME are used as control drugs. There are 13 drug treatments in the test, and each treatment is repeated 4 times. After 3 days and 10 days, investigate and record the insect population base, and calculate the control effect. The test results are shown in Table 6.

[0100] Table 6 Field test results of insecticidal cyclocycline and pyriproxyfen to control eggplant whitefly

[0101]

[0102] As can be seen from Table 6, the control effect of the insecticidal composition of the present invention is better than that of each control single agent treatment, indicating that the compounding of insecticidal cyclocyclone and pyriproxyfen can effectively control eggplant whitefly, and the persistence period is better than that of the control drug .

Abstract

The invention discloses an insecticidal composition containing insecticidal ring and pyriproxyfen, which contains active ingredients insecticidal ring and pyriproxyfen, and the weight ratio of insecticidal ring and pyriproxyfen in the composition is 1:30~ 30:1, the weight sum of insecticidal cyclocyclone and pyriproxyfen is 5%-90% by weight in the composition. According to actual application requirements, the insecticidal cyclocyclone and pyriproxyfen composition of the present invention can be prepared into water suspension concentrate, dispersible oil suspension concentrate, water emulsion, microemulsion, wettable powder or water dispersible granule, which is applied to the prevention and treatment of eggplant fields. Thrips, whitefly.

Description

technical field [0001] The invention relates to an insecticidal composition containing insecticidal cyclocyclone and pyriproxyfen, which is used as active ingredients to control thrips and whitefly in eggplant fields. Background technique [0002] Eggplant is one of the main vegetables in my country. Thrips and whitefly are common pests in the planting process of eggplant. They often hide behind the eggplant leaves and suck the juice, causing the eggplant leaves to die and deform. Due to long-term monotherapy, neonicotinoid insecticides, biogenic insecticides, organophosphorus insecticides and pyrethroid insecticides have developed severe resistance. At present, the ingredient with better effect on preventing and treating thrips in the market is spinosad, and the ingredient with better effect on controlling whitefly is spirotetramat. However, these two products are patented products of Dow AgroSciences of the United States and Bayer of Germany, respectively, and cannot be i...
