Embodiment 1

[0022] Combined Toxicity of Propyridine and Spinosad in Different Ratio

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

[0024] The toxicity of propargite, spinosad and their compound samples to spider mite was determined by dipping glass 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, spinosad and their compound samples to spider mite

[0026]

[0027] The data in the table shows that the mixture of propargid and ethyl spinosyn has a synergistic effect on spider mite, and the co-toxicity coefficients of the four ratios listed in the table are all...

Embodiment 2

[0029] Weighing propargid and ethyl spinosad are prepared in different proportions by conventional preparation methods to prepare propargid-ethyl spinosad emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.

[0030] Test method The method of soaking the leaves first and then inoculating the insects was used to determine the toxicity of propargite, spinosad and their compound samples to rice planthoppers. Each treatment was repeated 3 times, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0031] Table 2 Toxicity determination and co-toxicity coefficient of propargite, spinosad and their compound samples to rice planthopper

[0032]

[0033] The data in the table shows that the mixture of propargid and ethyl spinosad has a synergistic effect on rice planthoppers, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. Theref...

Embodiment 3

[0035] Weigh 5g of propargid, 20g of ethyl spinosad, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and xylene to 100g, and put the above raw materials into Mix in a mixing tank to form propargite-ethyl spinosad emulsifiable concentrate with a main active ingredient weight percentage of 25%.

[0036] The sample that adopts embodiment 3 to carry out the field test of preventing and treating spider mite in field, contrast agent is 57% propargite EC and 6% ethyl spinosad SC, and concrete consumption is shown in Table 3, and the water consumption of every mu is 30kg, medicine Check the results after 3 days, 7 days, 14 days, and 28 days. The test results are shown in Table 3:

[0037] Table 3 example 3 sample is to the field test result of spider mite

[0038]

[0039]

[0040] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on red spider mites, and has a relatively long duration of effect, and performs well i...

Abstract

The invention discloses a synergistic insecticidal composition containing propargite and ethyl spinosad and the application of the synergistic insecticidal composition. The insecticidal composition takes the propargite and the ethyl spinosad as main active ingredients, wherein the propargite and the ethyl spinosad are in the weight ratio of 1:60-60:1. The composition disclosed by the invention can prevent and control a plurality of insects, and has an obvious synergism; the insecticidal spectrum is enlarged; the synergistic insecticidal composition has high activity on the insects, such as diamondback moths, spodoptera exigua, leaf miners, thrips, prodenia litura, etiella zinckenella, red spiders and mites; the using amount of pesticides is reduced; the residue amount of the pesticides on crops is reduced; the environmental pollution is lightened; the synergistic insecticidal composition is safe to human and animals and high in environmental compatibility; the insects do not generate pesticide resistance easily.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with propargite and spinosad 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] Spinetoram, structural formula: [0006] [0007] Ethyl spinosad is a new type of spinosad insecticide produced by Dow AgroSciences. It is composed of ethyl spinosad-J and ethyl spinosad-L...
