Embodiment 1

[0022] Combined Toxicity of Different Proprietary Proprietate and Benfate

[0023] Weighing propargid and benzadil were prepared in different proportions by conventional preparation methods to prepare a propargid-benzadil suspension concentrate with a main active ingredient weight percentage of 30%. See Table 1 for specific proportions.

[0024] The toxicity of propargite, benzapter and their compound samples to Panonychus citrus was determined by dipping slides. Each treatment was repeated 3 times, and 30 heads were treated at each concentration. 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0025] Table 1 Toxicity determination and co-toxicity coefficient of propargite, benzapter and their compound samples against Panonychus citrus

[0026]

Embodiment 2

[0028] Weighing propargite and benzapterate were prepared in different proportions by conventional preparation methods to prepare propargite-benzapterate emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.

[0029] The test method adopts the leaf butterfly spray method (refer to "NY / T 1154.13-2008 Pesticide Indoor Bioassay Test Guidelines for Insecticides. Part 13: Leaf Butterfly Spray Method") to determine the pair of propargite, benzapter and their compound samples. Toxicity of Tetranychus cinnabarinus in cotton, repeated 3 times for each treatment, with LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0030] Table 2 Toxicity determination and co-toxicity coefficient of propargite, benzapter and their compound samples on cotton Tetranychus cinnabarinus

[0031]

Embodiment 3

[0033] Weigh 5g of propargite, 20g of benzate, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and xylene to 100g, and put the above raw materials into the mixing kettle according to the conventional method of preparing emulsifiable concentrate Mixed to form propargite-benzant emulsifiable concentrate whose main active ingredient is 25% by weight.

[0034] Adopt the sample of embodiment 3 to carry out the field test of field prevention and control of citrus Panonychus citrus. Check the results of 3 days, 7 days, and 14 days. The test results are shown in Table 3:

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

[0036]

[0037] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on Panonychus citrus, and has a relatively long duration of action, and performs well in the field. It is an excellent agent for preventing and controlling Panonychus citrus.

Abstract

The invention discloses a synergistic insecticide composition containing propargite and benzomate and application thereof. The insecticide composition uses the propargite and the benzomate as main active ingredients, wherein the weight ratio of the propargite to the benzomate is 1:60-60:1. The composition provided by the invention can be used for preventing and controlling various pests including mite pests and Lepidoptera pests; an obvious synergistic effect is achieved; the insecticidal spectrum is expanded; the insecticide consumption is reduced; the residue of the insecticide on crops is reduced; the environment pollution is reduced; the synergistic insecticide composition is safe for people and livestock; the environment compatibility is good; the pests cannot easily generate insecticide resistance.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with propargite and benzapter 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] Benzomate, molecular formula: C 18 h 18 C l NO 5 , chemical name: 3-chloro-α-ethoxyimino-2,6-dimethoxybenzyl benzoate, structural formula: [0006] [0007] Benzate is a new type of o...
