observations on equine strongyle control in southern temperate usa.a program of rotational anthelmintic treatments at eight-week intervals had failed to provide satisfactory equine strongyle control at a stable in southern usa. anthelmintic resistance had rendered benzimidazoles ineffective, and intervals between treatments with other drugs were too great to prevent environmental contamination with ova. ivermectin treatments at eight week intervals or pyrantel pamoate treatments at four week intervals successfully reduced egg counts for the majority of the summ ...19873504760
