Lodging management for Commander[PBR] – Moree, Gurley and Breeza 2012

Abstract

Key findings • In all trials PGR treatments were shown to reduce lodging to some degree, which was most likely a function of the reduced plant height obtained from PGR applications. • Yield responses to PGR application ranged from –13% to +16% for Commander[PBR] and Oxford[PBR] compared to the untreated control. Commander[PBR] was usually more responsive to the application of PGRs than Oxford[PBR]. • Of the PGR treatments the combined Cycocel® + Moddus® treatment resulted in the most consistent reduction in plant height and greatest responses in grain yield, whether negative or positive. • These results highlight the variability in responses to PGR application, which makes it difficult to accurately predict the economic benefit of using PGRs within cropping systems.
