Embodiment 1

[0021] Combined toxicity of different ratios of etoxazole and silymethrin

[0022] Weighing etoxazole and sethrin were prepared in different proportions by conventional preparation methods to prepare etoxazole-sethrin suspension concentrate with a main active ingredient weight percentage of 30%. See Table 1 for specific proportions.

[0023] The toxicity of etoxazole, silymethrin and their compound samples to citrus spider mite was determined by dipping glass slides, each treatment was repeated 3 times, each concentration treated 30 heads, and LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0024] : Table 1 etoxazole, silymethrin and its compound samples are to the toxicity determination and co-toxicity coefficient of citrus spider mite

[0025]

[0026] The data in the table shows that the mixture of etoxazole and sethrin has a synergistic effect on citrus spider mite, and the co-toxicity coefficients of the four ratios listed in the table...

Embodiment 2

[0028] Weigh etoxazole and sethrin and prepare etoxazole-sethrin emulsifiable concentrate with a main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. See Table 2 for specific proportions.

[0029] Test method The method of soaking the leaves first and then inoculating the insects was used to determine the toxicity of etoxazole, sethrin and their compound samples to the striatellus striatellus. Each treatment was repeated 3 times, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0030] Table 2 Toxicity determination and co-toxicity coefficient of etoxazole, sethrin and their compound samples to SBPH

[0031]

[0032] The data in the table shows that the mixture of etoxazole and sethrin has a synergistic effect on SBPH, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. Therefore, etoxazole and sethrin Ester blending has a signif...

Embodiment 3

[0034] Weigh 5g of etoxazole, 20g of sethrin, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and xylene to 100g, and put the above raw materials into the mixing tank according to the conventional method of preparing emulsifiable concentrate and mixed to form etoxazole-sethrin emulsifiable concentrate whose main active ingredient is 25% by weight.

[0035] Adopt the sample that embodiment 3 is equipped to carry out the field test of preventing and treating citrus spider mite in field, contrast agent is 15% etoxazole WP and 10% sethrin EC, and concrete consumption is shown in Table 3, and water consumption per mu is 30kg, after medicine Check the results of 3 days, 7 days, 14 days, and 28 days. The test results are shown in Table 3:

[0036] Table 3 example 3 sample is to the field test result of citrus spider mite

[0037]

[0038] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on citrus spider mite, and has...

Abstract

The invention discloses a synergistic insecticidal composition containing etoxazole and silafluofen, and a use thereof. The c insecticidal composition adopts etoxazole and silafluofen as main effective components, wherein a weight ratio of etoxazole to silafluofen is 1:60-60:1. The composition can prevent and control various pests, has an obvious synergistic effect, enlarges the insecticidal spectrum, has high activity on red spiders, spider mites, red mites, cotton bollworms, corn borers, beet armyworms, rice hoppers and prodenia litura on cereal crops, fruit trees, flowers, cotton and vegetables, and has the advantages of reduction of the pesticide consumption, reduction of the residual quantity of pesticides on crops, mitigation of the environment pollution, safety to humans and animals, good environmental compatibility, and difficult pesticide resistance of the pests.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with etoxazole and sethrin as main active ingredients and an application thereof. Background technique [0002] Etoxazole (etoxazole), the structural formula is: [0003] [0004] Etoxazole is a new acaricide with a special structure developed by Sumitomo Chemical Co., Ltd., Japan. It belongs to 2,4-diphenyloxazole derivatives and is a selective acaricide. Its mode of action is to inhibit the embryonic formation of mite eggs and the moulting process from larvae to adults. It is effective for eggs and larvae, but not for adults. Therefore, the best control time is the early stage of pest mite damage. The agent has strong rain resistance, long lasting effect, low dosage, is safe to the environment, and has no or minimal harm to beneficial insects and beneficial mites. [0005] Silafluofen, structural formula: [0006] [0007] Silfethrin i...
