Wild oat control with pre-emergent herbicides in barley locations

To evaluate the performance of new pre-emergent herbicides on the control of wild oats.

Key messages
  • A combination of Monza and Sakura applied PSPE provided the highest levels of wild oat control (68%)
  • Even with good control a high weed density remained (>200 plants per square metre) which would still be expected to cause significant crop yield losses (90%)
