A Disease of the Australian Grass Microlaena stipoides R.Br. caused by a Nematode, Anguillulina microlaenae n. sp.

Abstract

There have been no previous records of nematode invasion of native grasses in Australia, although “Cockle” in wheat, caused by Anguillulina tritici, and root galls on wheat, due to A. radicicola are known to occur. Mr. J. E. Harrison, Senior Agrostologist, Department of Agriculture, Victoria, found Microlaena stipoides infected as herein described at Lorne in April, 1935. This seems to be the first record of the disease, but it has since been ascertained that it is widely distributed in Victoria.
