In practice: bovine nematode control in the face of resistance: fourteen years of adaptive strategies

Abstract

Integrated Nematode control of bovines in Argentina has been considered "state of the art" for many years because it comprises diagnosis, reasonable use of drugs and epidemiology, and it involves a veterinarian with a holistic vision of the farm’s health and production objectives. In the year 2000 resistance to macrocyclic lactones was discovered and three years later, we found resistance to benzimidazol drugs.
