At the
GRDC supported Better
Oilseeds conference, Perth, Victoria-based consultant Dr Kate
Burke summarised best practice suggestions for Roundup® Ready
canola based on her observations of demonstration crops.
These included using appropriate pre-emergent herbicides, early
sowing, adequate nutrition and two applications of Roundup Ready
herbicide at the cotyledon and four leaf stage.
"In paddocks with high ryegrass populations and a strong
glyphosate history, there's a risk of glyphosate resistance and
the extra strategies identified in Monsanto's paddock risk
assessment management option guide (PRAMOG) process are
important to avoid resistance. Good management is essential.
"Wisely used, Roundup Ready canola can be a powerful tool to
strategically drive ryegrass numbers down and allow paddocks to
return to cereal production," Dr Burke said. |
