Organic compounds
View Patent ↗The invention relates to the use of aminoacetonitrile compounds of formula (I), wherein R 1 , R 2 , R 3 , R 4 , R 8 , R 9 , A, m and n have the significances given in claim 1 , in the control of endoparasites, especially helminths, in warm-blooded productie livestock and domestic animals.
1. A method of controlling Haemonchus contortus and Trichostrongylus colubriformis helminthes in warm-blooded domestic animals comprising administering a composition to said domestic animals, wherein said composition comprises a pesticidally active amount of the compound of the formula
and optionally enantiomers thereof.
2. A method of controlling helminthes in domestic animals comprising administering a composition to said domestic animals, wherein said composition comprises a pesticidally active amount of a compound of the formula
wherein
R 2 signifies unsubstituted phenyl or phenyl mono- or di-substituted by R 5 ;
n is 0 or 1;
R 1 is methylene which is substituted by unsubstituted phenyloxy or phenyloxy mono- or disubstituted by R 5 , whereby the substituents may be the same as one another or different if the number thereof is greater than 1; and
R 5 signifies halogen-C 1 -C 6 -alkyl, halogen-C 1 -C 6 -alkenyl, halogen-C 1 -C 6 -alkynyl, or halogen.
3. The method of claim 2 wherein said helminthes are endoparasitic nematodes.
4. The method of claim 3 wherein said endoparasitic nematodes are selected from the group consisting of Haemonchus, Trichostrongylus, Ostertagia, Nematodirus, Cooperia, Ascaris, Bunostonum, Oesophagostonum, Charbertia, Trichuris, Strongylus, Trichonema, Dictyocaulus, Capillaria, Heterakis, Toxocara, Ascaridia, Oxyuris, Ancylostoma, Uncinaria, Toxascaris , and Paracaris.
