Embodiment 1

[0019] Weighing propargid and acaridin are prepared in different proportions by conventional preparation methods to prepare a propargid-accaridin suspension concentrate with a main active ingredient weight percentage of 30%. See Table 1 for specific proportions.

[0020] The toxicity of propargate, acaricid and their compound samples to citrus spider mite was determined by dipping slide method, 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:

[0021] Table 1 Toxicity determination and co-toxicity coefficient of citrus spider mite to citrus red spider mite, acaridin and its composite samples

[0022]

Embodiment 2

[0024] Weighing propargid and acaridin are prepared in different proportions by conventional preparation methods to prepare propargidand acaridin emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.

[0025] The test method uses the leaf butterfly spray method (refer to "NY / T1154.13-2008 Indoor Bioassay Test Guidelines for Pesticides Insecticides. Part 13: Leaf butterfly spray method") to determine propargate, acaricide and their compound samples Toxicity to Tetranychus cinnabarinus, each treatment was repeated 3 times, with LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0026] Table 2 Toxicity determination and co-toxicity coefficient of propargite, acaridin and their compound samples to Tetranychus cinnabarinus

[0027]

[0028]

Embodiment 3

[0030] Weigh 5g of propargite, 20g of acaridin, 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 a propargate-acacid emulsifiable concentrate whose main active ingredient is 25% by weight.

[0031] 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 57% propargite EC and 16% acaricid EC, and concrete consumption is shown in Table 3, and water consumption per mu is 30kg, check after medicine. 3 days, 7 days, 14 days, 28 days results, the test results are shown in Table 3:

[0032] Table 3 example 3 sample is to the field test result of citrus spider mite

[0033]

[0034] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on citrus spider mite, and has a rel...

Abstract

The invention discloses a synergistic insecticidal composition containing propargite and tetranactin, and a use thereof. The c insecticidal composition adopts propargite and tetranactin as main effective components, wherein a weight ratio of propargite to tetranactin 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 diamondback moths, prodenia litura, rice hoppers, Chilo suppressalis and mites on fruit trees, tea leaves and flowers, 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. The composition can be processed to prepare a missible oil, an emulsion in water, a micro-emulsion, a suspension, a wettable pulvis or a water dispersible granule.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with propargate and acaricid 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] Tetranactin is a large tetracyclic lactone antibiotic extracted from Streptomycesaureus bacteria. It has strong acaricidal activity and can kill adults and eggs. It has low toxicity to humans...
