Embodiment 1

[0024] Weigh 30 g of clothianidin and flubendiamide, 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·flubendiamide emulsifiable concentrate with a main active ingredient of 30% by weight. The specific ratios of clothianidin and flubendiamide are shown in Tables 1 and 2.

[0025] The toxicity of clothianidin, flubendiamide and their compound samples to rice planthoppers was determined by the 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, flubendiamide and their compound samples to rice planthoppers

[0027]

[0028] The data in the ...

Embodiment 2

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

[0031] The toxicity of clothianidin, flubendiamide and their compound samples to cotton bollworm 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, flubendiamide and their compound samples to cotton bollworm

[0033]

[0034] The data in the table shows that clothianidin and flubendiamide have a synergistic effect on cotton bollworm after being mixed. The co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. Amide compounding has a significant synergistic effect. Among them, when the ratio of ...

Embodiment 3

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

[0037] The sample prepared in Example 3 was used to carry out the field test of rice planthopper prevention and control in the field. The contrast agent was 15% clothianidin EC and 20% flubendiamide WDG. The specific dosage is shown in Table 3. The water consumption per mu is 30kg. Check the results after 3 days, 7 days, 14 days, and 28 days. The test results are shown in Table 3:

[0038] Table 3 example 3 sample is to the field test result of paddy rice planthopper

[0039]

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

Abstract

The invention discloses a synergistic insecticidal composition containing clothianidin and flubendiamide and an application of the synergistic insecticidal composition. The clothianidin and the flubendiamide are used as main effective ingredients of the insecticidal composition, wherein the weight ratio of the clothianidin to the flubendiamide 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 pesticides containing heterocyclic compounds, and in particular relates to an insecticidal composition with clothianidin and flubendiamide as main active ingredients and an application thereof. Background technique [0002] Clothianidin, chemical name: E)-1-(2-chloro-1,3-thiazol-5-ylmethyl)-3-methyl-2-nitroguanidine; chemical formula: C 6 h 8 ClN 5 o 2 S; pure product is white crystal, melting point 176.8°C, vapor pressure (20°C) 3.8×10-11Pa, solubility (g / L, 25°C): 0.327 in water (20°C), 2.03 in ethyl acetate, n-heptyl <0.00104 in alkane, 0.0128 in xylene, 1.32 in dichloromethane, 0.938 in octanol, 15.2 in acetone, and 6.26 in methanol.
