Problems solved by technology

[0006] However, the resistance of homopteran pests, especially rice planthoppers and aphids, has gradually increased under the current long-term use of pesticides, and the effect of single-dose pesticides on pest control has gradually declined.
The inve...

Embodiment 1

[0019] Weighed dinotefuran and emamectin benzoate emulsifiable concentrates of 3% dinotefuran emamectin emamectin with a mass percent content of the main active ingredient in different proportions using conventional preparation methods. The contrast agents were 3% dinotefuran emulsifiable concentrate and 3 % Emamectin emamectin emulsifiable concentrate, see Table 1, 2 for the specific ratio.

[0020] Indoor synergistic bioassay was carried out by rice stem dipping method, the resistant rice planthopper was selected as the target pest, each treatment was repeated 3 times, and 60 heads were treated at each concentration, and the toxicological regression of each pesticide resistant rice planthopper was calculated by the probability value method Equation and lethal concentration LC 50 , with LC 50 The co-toxicity coefficient was calculated according to Sun Yunpei method, and the results are shown in Table 1:

[0021] Table 1 Toxicity determination of dinotefuran and emamectin be...

Embodiment 2

[0030] Weigh 2g dinotefuran, 3g emamectin benzoate, 3g phenethylphenol polyoxyethylene ether phosphate, and Nongru 33 # 2g, 1g of alkylphenol polyoxyethylene ether, 13g of mineral spirits, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing water emulsion, and mix at high speed to prepare a 5% dinotefuran-amamectin emamin salt water emulsion with a weight percentage of the main active ingredient.

Embodiment 3

[0032] Weigh 0.5g of dinotefuran, 4.5g of emamectin benzoate, 6g of calcium dodecylbenzenesulfonate, 3g of phenylethylphenol polyoxyethylene ether phosphate, and 33 grams of agricultural milk # 2g, 1g of alkylphenol polyoxyethylene ether, 10g of propylene glycol, add water to 100g. Put the above raw materials into a mixing tank according to the conventional method for preparing microemulsions and mix them to make a 5% dinotefuran-amamectin benzoate microemulsion with a main active ingredient weight percentage.

[0033] Example 3 is carried out to prevent and control rice brown planthopper efficacy test, contrast agent is 5% emamectin benzoate WDG and 5% dinotefuran WP, dilute according to the dilution multiple in table 3, apply 30 kilograms of medicinal liquid per mu after dilution, Check the results of 2 days, 5 days and 10 days after the medicine, and the processing results are shown in Table 3:

[0034] Table 3: Field test results of dinotefuran-amamectin salt compound on ...

Abstract

The invention discloses a composite insecticide composition containing dinotefuran and emamectin benzoate and a purpose thereof. The insecticide composition uses the dinotefuran and the emamectin benzoate as major effective ingredients, wherein the weight ratio of the dinotefuran to the emamectin benzoate is (0.1 to 80)/(0.5 to 80). The insecticide composition can be used for treating homoptera pests and hemiptera pests on crops and can be particularly used for preventing and treating delphacidae, whitefly, leafhopper and aphid, a higher synergy effect can be generated, the pest drug resistance is overcome and delayed, the insecticide speed is high, the duration is long, the medication cost is reduced, and the prevention and treatment effect is obviously higher than that obtained by using single agents.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a compound insecticidal composition containing dinotefuran and emamectin ectin and its application. Background technique [0002] Dinotefuran is a third-generation neonicotinoid insecticide developed by Mitsui Chemicals. Its chemical structure is very different from that of the existing neonicotinoid insecticides. Its tetrahydrofuryl group replaces the previous chloropyridyl and chlorothiazolyl groups, and it does not contain halogen elements. At the same time, it is also different from nicotine in terms of performance. Therefore, it is currently called "furan nicotine". Dinotefuran chemical name: 1-methyl-2-nitro-3-(tetrahydro-3-furylmethyl)guanidine, the structural formula is as follows: [0003] [0004] The new-generation neonicotinoid insecticide dinotefuran mainly acts on the neurotransmitter system of insects, paralyzing them to death. The agent has a wide inse...
