NSW Canola – 1998-2005

Plain text source: 
The research has been conducted across regional NSW to determine if new and existing varieties of canola vary in tolerance to commonly used herbicides... The sensitivity of the variety is summarised, using the following symbols based on the yield responses across all trials: - not tested or insufficient data no significant yield reductions at recommended rates or higher than recommended rates in 2+ trials N (narrow margin) significant yield reductions at higher than recommended rate in 1+ trials, but not at recommended rate x% yield reduction (warning) significant yield reduction at recommended rate in 1 trial only x-y% yield reductions (warning) significant yield reductions at recommended rate in 2+ trials.. It must be emphasised that crop tolerance and yield responses to herbicides are strongly influenced by seasonal conditions...
