Livestock poisonings: exposing a familiar culprit.
Deaths of cattle, sheep and horses by 'floodplains staggers' and 'Stewarts Range Syndrome' are thought to be caused by toxins accumulating in blown grass (Agrostis arenacea [A. avenacea?]) and in annual beard grass (Polypogon monspeliensis), respectively. The toxins are produced by Clavibacter as in annual ryegrass toxicity. It is hoped that a vaccine or toxin scavanger can be developed for the toxins.
