Embodiment 1

[0023] Weigh 30 g of clothianidin and flonicamid, 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·flunicamid emulsifiable concentrate with a main active ingredient of 30% by weight. The specific ratio of clothianidin and flonicamid is shown in Table 1.

[0024] The toxicity of clothianidin, flonicamid and their compound samples to rice planthoppers was determined by feed poisoning method, each treatment was repeated 3 times, and 30 heads were treated at each concentration, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

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

[0026]

[0027] The data in the table shows that ...

Embodiment 2

[0029] Weigh clothianidin and flonicamid and prepare clothianidin·flunicamid emulsifiable concentrate with 30% by weight of the main active ingredient 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, flonicamid and their compound samples to vegetable aphids, 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, flonicamid and their compound samples to vegetable aphids

[0032]

[0033] The data in the table shows that the mixture of clothianidin and flonicamid has a synergistic effect on vegetable aphids, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. Mixing has a significant synergistic effect. Among them, when the ratio of clothi...

Embodiment 3

[0035] Weigh 5g of clothianidin, 20g of flonicamid, 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 flonicamid emulsifiable concentrate whose main active ingredient is 25% by weight.

[0036] 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 10% flonicamid 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:

[0037] Table 3 example 3 sample is to the field test result of paddy rice planthopper

[0038]

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

Abstract

The invention discloses a synergistic insecticidal composition containing clothianidin and flonicamid and applications thereof. The synergistic insecticidal composition employs clothianidin and flonicamid as main effective components, wherein, the weight ratio of clothianidin to flonicamid is 1-100:1-100. The composition has high synergistic effects, delays drug resistance of insects, 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 hemiptera, coleopteran, lepidoptera, hymenoptera and the like with resistance.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with clothianidin and flonicamid 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.
