Abstract

Este trabalho teve por objetivo revisar os principais aspectos da intoxicação por Senecio spp. no Rio Grande do Sul no que se refere à patologia, patogenia e epidemiologia dessa importante causa de morte em bovinos nesse Estado. Foram abordados, também, os principais fatores climáticos e ambientais que aparentemente favorecem a emergência e o estabelecimento da planta e a ocorrência da intoxicação, que tem aumentado a sua frequência nos últimos anos no Estado, e as possíveis formas de controle da planta incluindo o manejo correto do solo e a utilização de espécies domésticas menos susceptíveis nas áreas invadidas.The study aimed to review the main aspects of Senecio spp. poisoning in Rio Grande do Sul, sou-thern Brazil, in relation to the pathology, pathogenesis and epidemiology of this important cause of death in cattle in that State.
