Abstract
A Townsville stylo (TS) pasture infested by annual grass species was subjected to mowing treatments for different periods at two cutting heights during the 1971/72 wet season and all to the same treatment during the 1972/73 wet season. Mowing to a height of 10 cm during the early and mid-wet season was the superior treatment with respect to TS content of the pasture both for the dry season following and the wet season of the next year. The effect of grass control seems to be related to reduced competition during the early stages of growth of TS rather than to grass seed control. The growth habits of the most important invading grass species are discussed.
