Embodiment 1

[0024] Weigh 30 g of clothianidin and chlorfluazuron, 4 g of calcium dodecylbenzenesulfonate, 3 g of phenethylphenol polyoxyethylene ether, and vegetable oil to 100 g. Put the above raw materials into a mixing tank according to the conventional method for preparing emulsifiable concentrate, and mix them to prepare clothianidin·chlorfluazuron emulsifiable concentrate with a main active ingredient of 30% by weight. The specific ratios of clothianidin and chlorfluazuron are shown in Tables 1 and 2.

[0025] The toxicity of clothianidin, chlorfluazuron and their compound samples to Plutella xylostella 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:

[0026] Table 1 Toxicity determination and co-toxicity coefficient of clothianidin, chlorfluazuron and their compound samples to Plutella xylostella

[0027]

[0028] The data in...

Embodiment 2

[0030] Weigh clothianidin and chlorfluazuron and prepare clothianidin·chlorfluazuron emulsifiable concentrate with a main active ingredient weight percentage of 30% by conventional preparation methods in different proportions. See Table 2 for specific proportions.

[0031] The toxicity of clothianidin, chlorfluazuron and their compound samples to Bemisia tabaci was determined by dipping method, each treatment was repeated 3 times, and LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0032] Table 2 Toxicity determination and co-toxicity coefficient of clothianidin, chlorfluazuron and their compound samples on tomato Bemisia tabaci

[0033]

[0034] The data in the table shows that clothianidin and chlorfluazuron have a synergistic effect on tomato whitefly after mixing, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. Mixing has a synergistic effect. Especially when the ratio of clothianid...

Embodiment 3

[0036] Weigh 5g of clothianidin, 20g of chlorfluazuron, 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 Mix to form clothianidin·chlorfluazuron emulsifiable concentrate whose main active ingredient is 25% by weight.

[0037] Adopt the sample that embodiment 3 is equipped to carry out the field experiment of field prevention and control vegetable diamondback moth, contrast agent is 15% clothianidin EC and 5% chlorfluazuron 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:

[0038] Table 3 example 3 sample is to the field test result of vegetable diamondback moth

[0039]

[0040] It can be seen from Table 3 that Example 3 has excellent quick-acting effe...

Abstract

The invention discloses a synergistic insecticidal composition containing clothianidin and chlorfluazuron and applications thereof. The synergistic insecticidal composition employs clothianidin and chlorfluazuron as main effective components, wherein, the weight ratio of clothianidin to chlorfluazuron is 1-80:1-80. 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.
