Evaluation of plant growth regulators in canola locations
Aims

To evaluate plant growth regulators currently used on canola in the UK.

Key messages

There was a reduction in plant height with all three treatments and this was generally rate responsive. As in a previous trial conducted in 2003-04 there was little effect on grain yield.
