Gastrointestinal worms in particular barber´s pole worm cause severe economic problems in all sheep growing districts of Queensland. This may occur every year in the higher rainfall zones or once every 3 or so years in the low-rainfall pastoral zones. Most rainfall occurs in summer with smaller falls in winter.
Worm burdens in sheep are severe enough to cause serious production losses and deaths.
The increasing resistance of worms to the chemicals used in drenches is a major challenge facing Queensland's sheep industry.
