Abstract
A control agent comprising, as an active ingredient, a specific quinoline derivative compound such as 8-fluoro-2,3-dimethyl-6-(1,1-dimethylethyl)-4-(methylcarbonyl)oxyquinoline, azoxystrobin, picoxystrobin, pyraclostrobin, kresoxim-methyl, trifloxystrobin, metominostrobin, orysastrobin, famoxadone, fluoxastrobin, pyribencarb, cyazofamid, amisulbrom, flutolanil, mepronil, isofetamid, fluopyram, carboxin, thifluzamide, fluxapyroxad, furametpyr, penflufen, penthiopyrad, boscalid, diflumetorim, fluazinam, ferimzone, fenpyroximate, or an acid addition salt of any of these compounds shows an excellent controlling effect on Mesostigmata mites.
Core Innovation
The invention relates to a Mesostigmata mite control method for veterinary hygiene problems. The method applies an effective amount of at least one active ingredient selected from compounds represented by Formula (1) and acid addition salts of these compounds to at least one selected from a Mesostigmata mite, a homoiotherm, an insect, and corresponding habitats.
In Formula (1), R1 is —COCH3, R2 is F or —CH3, and R3 is a t-Bu group. The invention thereby defines a specific class of quinoline derivatives for controlling Mesostigmata mites that harm homoiotherms and insects.
The document states that Mesostigmata mites to be controlled include Dermanyssus gallinae, Ornithonyssus sylviarum, Ornithonyssus bacoti, and Varroa destructor. Experimental support is described as controlling effects against red mites and northern fowl mites, with reported efficacy values presented in Tables 2 to 5 and comparison versus control drugs.
Claims Coverage
The independent claim covers a Mesostigmata mite control method using an effective amount of compounds represented by Formula (1) and their acid addition salts, applied to at least one selected target among mites, homoiotherms, insects, and their habitats. The dependent claims further narrow the application target by specifying spraying onto particular targets while retaining the Formula (1) structural constraints for the active ingredient.
Applying Formula (1) quinoline derivatives and acid addition salts to Mesostigmata mite-related targets
Applying an effective amount of at least one active ingredient selected from compounds represented by Formula (1) and acid addition salts, where R1 is —COCH3, R2 is F or —CH3, and R3 is a t-Bu group, to at least one selected from a Mesostigmata mite, a homoiotherm, an insect, a habitat of a Mesostigmata mite, a habitat of a homoiotherm, and a habitat of an insect.
Spraying directly onto a Mesostigmata mite
Spraying an effective amount of the active ingredient directly onto a Mesostigmata mite.
Spraying onto a homoiotherm or an insect parasitized by a Mesostigmata mite
Spraying an effective amount of the active ingredient onto a homoiotherm or an insect parasitized by a Mesostigmata mite.
Spraying onto a habitat of a Mesostigmata mite
Applying the active ingredient to a habitat of a Mesostigmata mite.
Overall, the claim set covers Mesostigmata mite control using Formula (1) compounds and their acid addition salts, with dependent claim refinement focusing on spraying to the mite itself, to associated homoiotherms or insects, or to habitats of the mites.
Stated Advantages
Improved/needed control due to reduced drug sensitivity.
Excellent controlling effect on Mesostigmata mites that harm homoiotherms and insects.
Documented Applications
Controlling effects against red mites and northern fowl mites.
Veterinary hygiene use cases involving Mesostigmata mites that harm homoiotherms and insects.
Comparison experiments versus control drugs including spinosad, trichlorfon, permethrin, propoxur, flumethrin, acequinocyl, and fluacrypyrim.
