Description

Technical Field

[0001] This invention belongs to the field of sanitary insecticides, specifically relating to an insecticidal composition and method for controlling sanitary pests. Background Technology

[0002] For a long time, the formulations and ingredients for controlling sanitary pests have been relatively limited, mainly including emulsifiable concentrates, water-in-oil emulsions, and microemulsions for space spraying, and wettable powders, suspensions, and water-dispersible granules for residual spraying. The active ingredients are mainly pyrethroid insecticides, organophosphate insecticides, neonicotinoid insecticides, and carbamate insecticides. The long-term repeated use of conventional formulations and active ingredients has greatly enhanced the resistance of pests, especially mosquitoes and flies, whose resistance has developed very rapidly. There is an urgent need for new active ingredients and formulation types for the control of sanitary pests.

[0003] Diamide insecticides, such as chlorantraniliprole, broflanilide, flubendiamide, tetrachlorantraniliprole, and broflanilide diamide, are suitable for foliar spraying and seed treatment. They can effectively reduce the damage caused by chewing insects. Some diamide insecticide varieties can also effectively control piercing-sucking insects, thrips, mites, coleopteran pests, and other pests. Their mechanism of action involves insect lysodin receptor allosteric activators and insect γ-aminobutyric acid receptor allosteric inhibitors, with stomach poisoning as the main effect and contact killing as a secondary effect. They are widely used in agriculture to control lepidopteran pests. Currently, only 0.5% broflanilide bait is commercially available for hygiene purposes.

[0004] Existing technology CN202211647666.7 discloses an insecticidal bait containing a piperic acid derivative compound and its application, mentioning that polyfluorinated biamide can be used as a bait to control cockroaches, ants, and red imported fire ants. The bait is a directly applicable granular bait, bait block, or gel bait. Existing patent WO2024 / 114260A1 discloses a binary insecticidal composition and its use, mentioning that polyfluorinated biamide can be combined with various active ingredients to control various pests on agricultural, forestry, and ornamental plants. However, the insecticidal effect of the mentioned insecticides still has room for further improvement. Summary of the Invention

[0005] The first objective of this invention is to provide an insecticidal composition, wherein the active ingredients of the insecticidal composition include polyfluorinated diamide and chlorfenapyr in a mass ratio of 1:3 to 19, and the formulation of the insecticidal composition is a stomach poison.

[0006] A second objective of the present invention is to provide a method for controlling sanitary pests, comprising: applying the insecticidal composition to the sanitary pests or their living environment.

[0007] This invention has discovered that although diamide insecticides are far less effective at killing sanitary pests than conventional pyrethroids and neonicotinoids, polyfluorinated diamide and chlorfenapyr have unique synergistic effects when combined, and can achieve better control performance through stomach poisoning.

[0008] Meanwhile, this invention further significantly enhances the control effect of polyfluorinated diamide and chlorfenapyr on sanitary pests by combining attractants and wetting and dispersing agents, and realizes the spraying application of bait. It has the characteristics of high efficiency, low toxicity and environmental protection, and has excellent effect in the control of sanitary pests. Detailed Implementation

[0017] In this invention, "stomach poison" refers to an insecticide that produces a toxic effect primarily after entering the digestive system of pests through ingestion.

[0018] This invention relates to an insecticidal composition, wherein the active ingredients of the insecticidal composition comprise polyfluorinated diamide and chlorfenapyr in a mass ratio of 1:3 to 19, and the formulation of the insecticidal composition is a stomach poison.

[0030] In some embodiments, the mass ratio of the active ingredient to the wetting and dispersing agent is 5:2 to 4.

[0031] In some specific embodiments, the mass ratio of the active ingredient to the wetting and dispersing agent can be any value within the range of 5:2, 5:2.3, 5:2.5, 5:2.8, 5:3, 5:3.2, 5:3.5, 5:3.7, 5:4, or 5:2 to 4.

[0032] In some embodiments, the insecticidal composition further includes a feeding attractant selected from one or more of amino acids, sugars, proteins, vitamins, and nucleotides; wherein the amino acids are selected from glycine, aspartic acid, benzo[a]ine, leucine, tyrosine, glutamic acid, alanine, and proline; and the sugars are selected from glucose, fructose, lactose, galactose, sucrose, maltose, erythrose, xylose, ribose, mannose, and arabinose.

[0033] In some preferred embodiments, the palatability enhancer comprises a mixture of amino acids and sugars. In some more preferred embodiments, the palatability enhancer comprises a mixture of glycine, alanine, and sucrose. In some further preferred embodiments, the mass ratio of glycine, alanine, and sucrose is 1:0.8–1.2:3–4.

[0034] The present invention further discovers that by adding a attractant, the control effect of the above-mentioned active ingredients on sanitary pests can be further enhanced. When the attractant includes amino acids and sugars, the resulting insecticidal composition has a better control effect on sanitary pests, especially the combination of glycine, alanine, and sucrose.

[0035] In some specific embodiments, the mass ratio of glycine, alanine and sucrose can be any ratio within the range of 1:0.8:3, 1:0.9:3.2, 1:1:3.4, 1:1:3.5, 1:1:3.6, 1:1:3.7, 1:1.1:3.8, 1:1.2:4, or 1:0.8 to 1.2:3 to 4.

[0077] Table 4 Suspension Rate Index Test

[0078]

[0079] The results showed that sodium lauroyl sarcosinate and fatty acid sucrose ester (SE-15) as wetting and dispersing agents can effectively improve the suspension rate of polyfluorinated biamide and chlorfenapyr in sugar and amino acid-containing systems. Conventional agricultural wetting and dispersing agents, except for the combination of sodium dodecylbenzene sulfonate and NNO, are difficult to achieve excellent dispersion and suspension performance.

[0080] Experimental Example 2

[0081] Test methods: Refer to GB / T13919.1-2009 Indoor efficacy test and evaluation of pesticides for registration as sanitary insecticides, spray test.

[0082] Experimental treatment: All formulation examples were diluted with water at a dosage of 25 mg / m².

[0083] Experimental target: Sensitive houseflies (indoor rearing).

[0084] The experimental results are shown in Tables 5-7 below.

[0085] Table 5. Results of indoor efficacy tests on houseflies with different ratios of active ingredients.

[0086]

[0087]

[0088] Since both agents primarily exhibit stomach poison activity against houseflies, the co-toxicity coefficient could not be calculated using the droplet method. However, the data above show that when the ratio of polyfluorfen diamide to chlorfenapyr is 1:3 to 19, it has excellent lethal synergistic effects, achieving a lethal effect significantly superior to that of a single agent.

[0091] The results show that the addition of a palatability attractant significantly improved the lethality of the insecticidal composition, achieving excellent control performance at a dosage of 50 mg / m². Furthermore, the wetting and dispersing agent combination of sodium lauroyl sarcosinate / sucrose fatty acid ester (SE-15) exhibited significantly higher lethality compared to the wetting and dispersing agent combination of sodium dodecylbenzenesulfonate / NNO, further demonstrating that improved palatability has a very significant impact on the stomach poison activity of the active ingredient.

[0092] Table 7. Results of indoor efficacy comparison test of houseflies with different attractant formulations.

[0093]

[0094]

[0095] The results showed that the combination of various amino acids and sugars improved the lethality rate to varying degrees compared with formulations in Examples 35-36, with the combination of glycine, alanine, and sucrose being the best. In practical implementation, other proteins, vitamins, nucleotides, flavorings, etc., can be added, or the above formulation can be made into a directly usable bait using conventional methods, which also has similar effects.
