Embodiment 1

[0023] Weigh 30 g of clothianidin, metaflumizone, 4 g of calcium dodecylbenzenesulfonate, 3 g of phenethylphenol polyoxyethylene ether, and vegetable oil to 100 g. The above raw materials are put into a mixing tank according to the conventional method for preparing EC and mixed to prepare Clothianidin Metaflumizone EC with a main active ingredient of 30% by weight. The specific ratio of clothianidin and metaflumizone is shown in Table 1.

[0024] The toxicity of clothianidin, metaflumizone and their compound samples to rice stem borer was determined by feed poisoning method. Each treatment was repeated 3 times, and each concentration was treated with 30 heads. 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0025] Table 1 Toxicity determination and co-toxicity coefficient of clothianidin, metaflumizone and their compound samples to rice stem borer

[0026]

[0027] The data in the table shows that clothianidin and metaflumizone have a synergis...

Embodiment 2

[0029] Weigh clothianidin and metaflumizone and prepare clothianidin metaflumizone emulsifiable concentrate with a weight percentage of 30% of the main active ingredients by conventional preparation methods in different proportions. See Table 2 for specific proportions.

[0030] The rice stem dipping method was used to determine the toxicity of clothianidin, metaflumizone and their compound samples to rice planthoppers, each treatment was repeated 3 times, and LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0031] Table 2 Toxicity determination and co-toxicity coefficient of clothianidin, metaflumizone and their compound samples to rice planthoppers

[0032]

[0033] The data in the table shows that clothianidin and metaflumizone have a synergistic effect on rice planthoppers after being mixed. Hydrazone mixing has a synergistic effect. When the ratio of clothianidin and metaflumizone is 1:1~10, the synergistic effect of mixing and killing...

Embodiment 3

[0035] Weigh 4g of clothianidin, 20g of metaflumizone, 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 Mixed in medium to make clothianidin metaflumizone EC with the weight percentage of the main active ingredient being 24%.

[0036]Adopt the sample of embodiment 3 to carry out the field experiment of controlling rice stem borer in field, contrast agent is 15% clothianidin EC and 22% metaflumizone 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 to the field test result of rice stem borer

[0038]

[0039] It can be seen from Table 3 that Example 3 has excellent quick-acting effect on rice stem borer, an...

Abstract

The invention discloses a synergistic insecticidal composition containing clothianidin and metaflumizone and applications thereof. The synergistic insecticidal composition employs clothianidin and metaflumizone as main effective components, wherein, the weight ratio of clothianidin to metaflumizone is 0.1-60:0.1-60. The composition can enlarge the control spectrum, has synergistic effects, and can lower drug cost. The composition can be prepared into missible oil, wettable powder, microemulsion, emulsion in water, suspending agents and water dispersion granules, and is used for control of various insects of lepidoptera, hemiptera, hymenoptera, coleopteran and the like.
