Description

Paclobutrazol and flurprimidol were applied to a mature stand of tall fescue (Festuca anmdi11acea Schreb. cv. Grasslands Roa) at l and 2 kg ai/ha at spikelet initiation (SI) and floret initiation (Fl) in 1985. Paclobutrazol at 2 kg ·ai/ha, applied at both SJ and FI, increased P(<0.05) seed yields but the lower paclobutr z I rate and flurprimidol had no significant effect on seed yields.
