Popis:	The efficacy of auxin/cytokinin (Kelpak) on its own and in a mixture with the herbicide clopyralid (Lontrel 100), for post-emergence application at various growth stages in canola (Brassica napus) was assessed. A Kelpak foliar application at 2 I ha−1 applied at the four leaf stage gave a significant increase in yield at Langgewens in 1999 compared to the control. At Tygerhoek, Kelpak at 2 I ha−1 significantly increased canola yields when applied at either the three leaf or five leaf growth stage of canola, but the highest yield, was obtained by Kelpak at 2 I ha−1 at the three leaf average growing stage of canola.
