Control of annual ryegrass with pre-emergence herbicides locations
Aims

To evaluate the efficacy & crop safety of alternate preemergent herbicides & their mixtures for the control of ryegrass in wheat.

Key messages
  • Boxer Gold alone or in combination with trifluralin and / or Avadex Xtra provided consistent pre-emergence control of ryegrass, as did trifluralin & Avadex Xtra.
  • Although ryegrass control with new pre-emergent herbicide Sakura was lower than in previous years, its tank mixture with Avadex Xtra provided excellent control (86%).
  • Boxer Gold & Dual Gold applied PSPE appeared to provide some additional in-row control of ryegrass.
