Problems solved by technology

[0010] If the above pesticides are used alone and for a long time, especially nereistin insecticides, the pests have developed a certain resistance after continuous long-term use, and there are large dosages, increased costs, and aggravated environmental pollution.
And there are disadvantages such as narrow insecticidal spectrum, poor quick-acting or persistent effect
In order to develop a quick-acting and long-lasting effect and reduce the cost of pesticides, on the basis of indoor bioassay screening and field experiments, we screened sulfoxaflor and nereistoxin compounds for dual compounding, which has obvious Synergistic effect, high efficiency and environmental protection, no relevant compound reports have been found so far after searching

example 1

[0054] (1) Test drug

[0055] 96% sulfoxaflor technical substance, 98% cartap technical substance, all of which are provided by Qingdao Hailier Pharmaceutical Co., Ltd.

[0056] (2) Source of tested insects

[0057] The third instar larvae of Plutella xylostella were reared continuously for 10 generations with radish seedlings indoors, at a temperature of (25±2)°C, a relative humidity of 50%±4%, and a photoperiod of 14 / 10h (L / D).

[0058] (3) single-dose determination method

[0059] Both groups of original medicines were dissolved with a small amount of acetone by worm soaking method, and then diluted with 0.1% Tween aqueous solution to form 5 concentrated solutions with equal difference, which were diluted in beakers for later use, and clear water was used as a control.

[0060] The third instar Plutella xylostella larvae of the same size were immersed in the liquid medicine soaked in the insect cage for 5 seconds, and after absorbing the excess liquid medicine, they were ...

example 2

[0077] (1) Experimental test agent

[0078] 96% of the original drug of sulfoxaflor and 36% of the parent drug of dimehypo, all of which are provided by Qingdao Hailier Pharmaceutical Group.

[0079] (2) Test target

[0080] Rice leaf roller, using rice leaf roller as the test object, the insect species were taken from the paddy field of Dalu Village, Zhaodian Town, Gaoqing County, artificially raised in the insect culture room for multiple generations, and selected healthy and consistent 4th to 5th instar nymphs ,spare.

[0081] Experimental method is the same as activity determination example 1

[0082] (3) Toxicity test results and analysis:

[0083] Table 2 Indoor test results of sulfoxaflor and dimehypo against rice leaf roller

[0084]

[0085]

[0086] It can be seen from the table that in the mixing of different proportions, the co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, and the synergistic effect of sulfoxaflor: ...

example 3

[0088] (1) Test drug

[0089] 96% of the technical sulfoxaflor and 95% of the technical monosultap are provided by Qingdao Hailier Pharmaceutical Co., Ltd.

[0090] (2) Source of tested insects

[0091] The third instar larvae of Plutella xylostella were reared continuously for 10 generations with radish seedlings indoors, at a temperature of (25±2)°C, a relative humidity of 50%±4%, and a photoperiod of 14 / 10h (L / D).

[0093] (3) Toxicity test results and analysis:

[0094] Table 3 Indoor determination results of sulfoxaflor and monosultap on Plutella xylostella

[0095]

[0096] It can be seen from the table that in the mixing of different proportions, the co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, and the synergistic effect of sulfoxaflor: monosultap at 5:15 is the best. Obviously, the co-toxicity coefficient is 154.74. The test results showed th...

Abstract

The invention belongs to the field of pesticide complex formulation, and relates to a pesticide composition. The pesticide composition is a two-component blended composition with effective components of sulfoxaflor and a nereistoxin compound. The weight ratio between the two components is 1 to 80:80 to 1, and preferably the weight ratio is 3 to 50:60 to 5. A total mass percentage of the effective components is 1% to 90%, and preferably 5% to 60%. The rest components are auxiliary components which are acceptable and applicable in pesticides. With the auxiliary components, the pesticide composition can be made into cream, suspending agent, wettable powder, water dispersible granules, aqueous emulsion, or micellar emulsion. The pesticide composition with sulfoxaflor and a nereistoxin compound as effective components has a substantial controlling effect against lepidoptera insects such as diamondback moth, beet armyworm, prodenia litura, cotton bollworm, chilo suppressalis, and mealybugs, and homoptera piercing-and-sucking mouthpiece pests such as plant hopper, aphid, whitefly, and leafhopper.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition which uses sulfoxaflor and nereistoxin compounds as active ingredients for dual compounding. Background technique [0002] Sulfoxaflor, its chemical name: [1-6-(trifluoromethyl)pyridin-3-yl]ethyl]-λ4-mercaptocyanamide; molecular formula: C 10 h 10 f 3 N 3 OS, the structural formula is: [0003] [0004] Sulfoxaflor is a sulfonylimide insecticide that acts on a unique binding site in the choline receptor to exert insecticidal function. It can be absorbed into plants through leaves, stems and roots. Sulfoxaflor is suitable for the control of cotton bugs, aphids, whiteflies, planthoppers and scale insects, etc.; it is efficient, fast and has a long residual effect, and can effectively control neonicotinoids, pyrethroids, organophosphorus and amino acids. Formate pesticides produce resistant sap-sucking pests. It has the advantages ...
