To determine the relative herbicide tolerance of Flip 94-090c, Flip 94-509c and Flip 94-508c.

Grain Yield results of these trials need to be treated with caution due to the adverse environmental
conditions experienced throughout the season.

• Growing season rainfall was extremely low (157mm c.f. 230mm long term average) and there was no subsoil moisture due to low summer rainfall. Only 8mm rainfall was recorded in r (a critical period for crop growth and yield determination). There was an extremely hot
  period during October which resulted in significant flower and pod abortion. Many plots had
  died without setting pods prior to harvest. The late rainfall of 50mm in November was too late to be of any benefit.
• Emergence was similar across all treatments and varieties.
• All varieties responded similarly to the herbicide treatments.
• The most significant damage was in simazine + imazethapyr and simazine + isoxaflutole
  treatments. Simazine + isoxaflutole applied at double rates caused a significant reduction in
  crop height.
• The trial was not harvested and grain yields not recorded as there was almost no pods set (see above).
