Control Strategies For Annual Ryegrass Toxicity, W J. Burdass
Control Strategies For Annual Ryegrass Toxicity, W J. Burdass
Journal of the Department of Agriculture, Western Australia, Series 4
In 982-83, annual ryegrass tocicity (ARGT) was estimated to have cost Western Australian sheep farmers between $7 and $8 million in total economic losses.
The disease can severely disrupt farming operations. Sheep must be checked daily and if affected moved to a 'safe' paddock. The availability of paddock feed is reduced, as is stock carrying capacity. Worry about the possibility of dramatic stock losses, and uncertainty about what decisions to make, are all stressful.
Stock losses from ARGT can be minimised by the use of selective herbicides to control ryegrass in pastures and crops. This breaks the disease cycle - …

Annual ('Wimmera') Ryegrass Toxicity, Geoffrey A. Pearce, O. M. Goss, P. H. Berry, J. L. Wise
Journal of the Department of Agriculture, Western Australia, Series 4
Because annual ryegrass is one of the most widespread pasture plants in Western Australia, annual ryegrass toxicity is a threat to livestock in many agricultural areas—even though the area now affected is small.
The problem is being intensively studied by the Department of Agriculture and a working group has been set up to investigate potential control measures.
In this article the group reviews the problem and reports progress in its investigations to the end of 1973.

Wimmera ryegrass toxicity has been reported for many years to affect sheep and occasionally cattle in New Zealand, South Australia and the United States of America.
In Western Australia, occasional reports since 1959 and severe outbreaks of staggers in the Katanning- Gnowangerup areas over the last two years prompted the investigation reported below.
