Abstract Extract Phalaris tuberosa, a common pasture plant, may on occasions cause inco-ordination (staggers) and/or death in sheep and cattle (McDonald, 1942 McDonald, I. W. 1942. A "staggers" syndrome in sheep and cattle associated with grazing on Phalaris tuberosa. Aust. vet. J., 18: 182–189. [Google Scholar]; Le Soeuf, 1948 Le Soeuf, H. D. 1948.

Acutetoxicity may be manifested by sudden death(Moore et al, 1961 Moore, R. M., Arnold, G. W., Hutchings, R. J. and Chapman, H. W. 1961. Poisoning of Merino Sheep on Phalaris tuberosa L. pastures.
