Abstract
A herbicide trial and demonstration was commenced in 1973 and the treatment repeated in 1974. the objective was to control the annual ryegrass which was the dominant species and allow the scattered plants of sub clover to re-establish a clover dominant pasture. (See table) Despite the high reduction of seed stalks formed on some treatments in 1973 the ryegrass was only reduced by 50 per cent on the best treatment in 1974, The reduction in seed production in 1974 will no doubt further reduce the density of ryegrass in 1975 but eradication is unlikely. The value of burning in destroying viable seed, nematode galls and bacteria infected seeds can be summarised (See Table) Newdegate Research Station 74N14, Newdegate Research Station 74N15, Wongan Hills Research Station 74WH31, Merredin Research Station 64M15.
