Embodiment 1

[0021] Combined Toxicity of Propyridine and Promethrin in Different Ratio

[0022] Weighing propargid and promethrin are prepared in different proportions by conventional preparation methods to prepare propargid-promethrin suspension concentrate with the weight percentage of the main active ingredient being 30%. See Table 1 for specific proportions.

[0023] The toxicity of propargite, promethrin and their compound samples to citrus spider mite was determined by dipping 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 Toxicity determination and co-toxicity coefficient of citrus spider mite to citrus red spider mite, promethrin and its composite samples

[0025]

Embodiment 2

[0027] Weighing propargid and promethrin are prepared in different proportions by conventional preparation methods to prepare propargid-promethrin emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.

[0028] Test method The method of soaking the leaves first and then inoculating the insects was used to determine the toxicity of propargite, promethrin and their compound samples to cabbage caterpillars. Each treatment was repeated 3 times, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0029] Table 2 Toxicity determination and co-toxicity coefficient of propargite, protothrin and their compound samples to cabbage caterpillar

[0030]

[0031] The data in the table shows that propargid and protothrin have a synergistic effect on cabbage caterpillar after mixing, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120, so prop...

Embodiment 3

[0033] Weigh 5g of propargite, 20g of cyprothrin, 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 a propargite-methrin emulsifiable concentrate whose main active ingredient is 25% by weight.

[0034] Adopt the sample of embodiment 3 to carry out the field test of controlling citrus spider mite in field, contrast agent is 57% propargite EC and 2.0% fenthrin GR, and concrete consumption is shown in Table 3, and water consumption per mu is 30kg, after the medicine Check the results of 3 days, 7 days, 14 days, and 28 days. The test results are shown in Table 3:

[0035] Table 3 example 3 sample is to the field test result of citrus spider mite

[0036]

[0037] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on citrus spider mite, and has a relativel...

Abstract

The invention discloses a synergistic insecticidal composition containing propargite and cycloprothrin and application thereof. The insecticidal composition takes propargite and cycloprothrin as main effective components, wherein the weight ratio of propargite to cycloprothrin ranges from (1:60) to (60:1). The composition provided by the invention can be used for preventing and treating a plurality of types of injurious insects, has a remarkable synergistic effect and can be used for expanding the insecticidal spectrum; the synergistic insecticidal composition has relatively high activity on prodenia litura, cabbage caterpillars, aphids, red spiders, spider mites, panonychus ulmi, soybean pod borers, leaf miners and the like of cotton, rice, soybeans, vegetables, fruit trees and tea trees; the dosage of pesticides is reduced, the residual amount of the pesticides on crops is reduced and the environmental pollution is alleviated; and the synergistic insecticidal composition is safe to human and livestock and has good environment compatibility, and the injurious insects cannot easily have drug resistance.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with propargite and promethrin as main active ingredients and an application thereof. Background technique [0002] Propargite, molecular formula: C 19 h 26 o 4 S, chemical name: 2-(4-tert-butylphenoxy)cyclohexylpropyn-2-yl sulfite. The structural formula is: [0003] [0004] It is a broad-spectrum, high-efficiency, and low-toxicity acaricide, which has contact and stomach poisoning effects, and has no penetration and systemic effects. It has good effect on juvenile nymphs and adult mites, but poor ovicidal effect. It can effectively control spider mite pests on apple trees, cotton, cucumbers, grapes, corn, soybeans, tomatoes and vegetables. [0005] Cyclopropanecarboxylic acid, structural formula: [0006] [0007] Promethrin is a low-toxicity pyrethroid insecticide, which mainly has contact action, has certain stomach toxicity, and...
