Integrated weed management demonstrations to improve adoption of wild radish control practices- Dalwallinu locations
Aims

To conduct integrated weed management IWM trials investigating chemical and non-chemical weed control options to minimise the impact of herbicide resistance in wild radish in Western Australian (WA) Wheatbelt and to improve adoption of wild radish IWM.

Key messages
  • Application of knockdown and in-crop herbicides from diverse modes of action at early and late stages provided excellent radish control (97 to 100%).
  • A higher gross margin came from the 60 kg/ha seed rate than the 120 kg/ha in 2014 season mainly due to greater grain yield and lower seed costs at 60 kg/ha.
  • Increasing pressure on knockdown, in-crop herbicides from diverse modes of action, and seed rate reduced gross margin but provided superior radish control.
  • Wild radish has developed resistance to most of the available selective and non-selective herbicides including glyphosate in Western Australia. It is important that an integrated weed management (IWM) approach including as many weed control options as possible should be adopted by growers to manage wild radish.
