Embodiment 1

[0022] Weigh 30 g of ethiprole and metaflumizone, 5 g of calcium dodecylbenzenesulfonate, 6 g of phenethylphenol polyoxyethylene ether, and 100 g of vegetable oil. Put the above raw materials into a mixing tank according to the conventional method for preparing EC, and mix them to prepare ethiprole-metaflumizone EC with a main active ingredient of 30% by weight. The specific ratios of ethiprole and metaflumizone are shown in Tables 1 and 2.

[0023] The toxicity of ethiprole, metaflumizone and their compound samples to rice stem borer was determined by feed poisoning method. 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:

[0024] Table 1 Toxicity determination and co-toxicity coefficient of ethiprole, metaflumizone and their compound samples to rice stem borer

[0025]

[0026] The data in the table shows that the mixture of ethiprole and metaflumizone has a s...

Embodiment 2

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

[0029] The rice stem dipping method was used to determine the toxicity of ethiprole, metaflumizone and their compound samples to rice brown planthopper, each treatment was repeated 3 times, and LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0030] Table 2 Toxicity determination and co-toxicity coefficient of ethiprole, metaflumizone and their compound samples to rice brown planthopper

[0031]

[0032] The data in the table shows that the mixture of ethiprole and metaflumizone has a synergistic effect on brown planthoppers, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120, so the mixture of ethiprole and metaflumizone With a significant syn...

Embodiment 3

[0034] Weigh 5g of ethiprole, 20g of metaflumizone, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and solvent oil to 100g, and put the above raw materials into the mixing tank according to the conventional method of preparing emulsifiable concentrate Mix in medium to form ethiprole metaflumizone emulsifiable concentrate whose main active ingredient is 25% by weight.

[0035] The sample prepared in Example 3 was used to carry out the field test of rice brown planthopper control in the field. The contrast agent was 25% ethiprole WP and 25% metaflumizone EC. The specific dosage is shown in Table 3. 3 days, 7 days, 14 days, 28 days results, the test results are shown in Table 3:

[0036] Table 3 example 3 sample is to the field test result of rice brown planthopper

[0037]

[0038]

[0039] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on rice brown planthopper, and performs well in the field, and is an e...

Abstract

The invention discloses a synergistic insecticidal composition containing ethiprole and metaflumizone and an application of the synergistic insecticidal composition. The ethiprole and the metaflumizone are used as insecticidal active ingredients of the composite insecticidal composition, wherein the weight ratio of the ethiprole to the metaflumizone is (0.1-80): (0.5-80). The insecticidal composition has the effects of expanding a prevention and control spectrum and synergizing, can be used for reducing the pesticide cost, and can be prepared into emulsion oil, wettable powder, a microemulsion, a water emulsion, a suspending agent and water dispersible granules to prevent and control various pests such as lepidoptera, hemiptera, hymenoptera, coleoptera and the like.

Description

technical field [0001] The invention belongs to the field of agricultural insecticides containing heterocyclic compounds, and specifically relates to a compound insecticidal composition. Background technique [0002] Ethiprole, chemical name: 1-(2,6-dichloro-4-trifluoromethylphenyl)-3-cyano-4-ethylsulfinyl-5-aminopyrazole. The molecular formula is: C 13 h 9 C l2 f 3 N 4 OS. [0003] Ethiprole is an insecticide and acaricide discovered by Rhone Planck and developed by Bayer. It belongs to the second generation of insecticides that act on GABA and is effective against various chewing and sucking pests at low dosages. Effective, it can be used for seed treatment and foliar spray, and the duration of effect is as long as 21-28d. (mainly used for the control of thrips, stinkbugs, weevils, sugar beet moths, aphids, planthoppers and locusts, etc., and also exhibits activity against some whiteflies (especially for rice green bugs, which are extremely difficult to control rice...
