As the crop approaches maturity, terminating growth
with a pre-harvest herbicide application is strongly
recommended. Spraying is essentially the replacement
for swathing. This will allow the crop to dry down
uniformly. If the crop is not terminated, later maturing
plants or patches will delay combining. The selection of
the product used to terminate crop growth will depend
on the herbicide tolerant canola system. Glyphosate can
be used in LibertyLink ® and Clearfield ® canola. Apply it
at about the same time as swathing. Glyphosate works
slow and can take three to four weeks before attempting
to combine. Desiccant-type products such as Heat ® or
Reglone ® (Stage) ® are faster acting but provide minimal
pre-harvest perennial weed management benefits.
