Problems solved by technology

[0007] The activity of chlorothialine is 20 times that of general neonicotinoid insecticides (such as: acetamiprid, imidacloprid), and it is not limited by temperature, which overcomes the poor control effect of acetamiprid, imidacloprid and other products at low temperatures Because chlorothialine is a new type of single-dose pesticide, it is not widely used in China at present, and pests have no resistance to it
It has low toxicity, meets the requirements of pollution-free agricultural production, and has a wide insecticidal spectrum. It can be used on a variety of crops. In addition to controlling rice leafhoppers, planthoppers, and thrips, it is also effective against Coleoptera, Diptera, and Lepidoptera pests. Especially highly toxic to rice stem borer and rice stem borer, other neonicotinoid insecticides (acetamiprid, imidacloprid) are incomparable
[0008] Single-component clothianidin and chlorothialine often have defects in the control of pesticide pests: continuous use is easy to produce resistance, narrow insecticidal spectrum, cannot provide comprehensive protection for crops, and the cost of pesticides for farmers is high.

Embodiment 1

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

[0024] The rice dipping method was used to determine the toxicity of clothianidin, chlorothialine and their compound samples to rice planthoppers. 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, chlorothialine and their compound samples to rice planthoppers

[0026]

[0027] The data in the ta...

Embodiment 2

[0029] Clothianidin and clothialine were weighed and prepared in different proportions by conventional preparation methods to prepare clothianidin chlorothialine emulsifiable concentrate with a main active ingredient weight percentage of 30%. See Table 2 for specific proportions.

[0030] The toxicity of clothianidin, chlorothialine and their compound samples to rice stem borer 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:

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

[0032]

[0033] The data in the table shows that clothianidin and chlorothialine have a synergistic effect on rice stem borer after mixing, and the co-toxicity coefficients of the four ratios listed in the table are all far greater than 120. Therefore, clothianidin and chlorothialine Mixing has a signif...

Embodiment 3

[0035] Weigh 5g of clothianidin, 20g of chlorothialine, 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 make clothianidin · chlorothialine emulsifiable concentrate whose main active ingredient weight percent content is 25%.

[0036] Adopt the sample of embodiment 3 to carry out the field test of rice planthopper prevention and control in field, contrast agent is 15% clothianidin EC and 10% chlorothialine WDG, and concrete consumption is shown in Table 3, and the water consumption per mu is 30kg, after the medicine Check the results of 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-acti...

Abstract

The invention discloses a synergistic insecticidal composition containing clothianidin and imidaclothiz and applications thereof. The synergistic insecticidal composition employs clothianidin and imidaclothiz as main effective components, wherein, the weight ratio of clothianidin to imidaclothiz is 0.1-50:0.1-50. The composition has high synergistic effects, enlarges the control spectrum, 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.
