To determine the place of longer season canola varieties in south east SA and what agronomic treatments may increase grain yield.
Mowing to simulate grazing reduced grain yield and plant height. The application of Prosaro at the 3-4 leaf stage increased grain yield over the nil application treatment by reducing the level of internal infection caused by blackleg. The later application of Prosaro (8-10 leaf stage) also decreased the amount of blackleg compared to either the nil or the mowed at 8-10 leaf treatments.
