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.

Example Embodiment

[0023] Example 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 table shows that clothianidin and flubendiamide have a synergistic effect on rice planthoppers after being mixed. Bisamide blending has a significant synergistic effect. Among them, when the ratio of flubendiamide and clothianidin was 1:1, the synergistic effect on killing rice planthoppers was the greatest, and the co-toxicity coefficient was 206.28.

Example Embodiment

[0029] Example 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 clothianidin and flubendiamide was 1:5, the synergistic effect on killing cotton bollworm was the greatest, and the co-toxicity coefficient was 219.32.

Example Embodiment

[0035] Example 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 rice planthoppers, and has a relatively strong persistence period, and performs well in the field. It is an excellent agent for controlling rice planthoppers.
