Annual ryegrass toxicity (ARGT) is a complex disease that kills sheep and cattle grazing pastures which contain infected ryegrass. The disease results when a nematode (Anguina agrostis) and a batcerium (Corynebacterium sp.) invade annual ryegrass and cause the seed heads to become toxic as the grass dries off.
The bacterium produces a complex toxin of 18 glycolipid compounds or corynetoxins which have been found to be virtually identical to the antibiotic tunicamycin.

Many District Advisers have carried out trials on private farms to test the response to a variety of types of supplementary feeds. This report gives brief details of five such experiments carried out with urea supplements over the last five years. Table 1 summarises the details and results of these trials.
