Evaluation of plant growth regulators in canola locations
Aims

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

Key messages

Application of metconazole to canola resulted in a reduction in plant height but in this trial there was no effect on grain yield. Tebuconazole had no effect on plant height or final yield. In seasons where excess vegetative growth is a problem increases in grain yield following treatment could be expected through improved harvest efficiency (less lodging and/or redirection of plant assimilates to the grain).
