Improve herbicide rotation strategy with a focus on reducing selection pressure and dependence on imidazolinone (IMI) herbicides.
Compare the level of weed control achieved with low and high inputs of non-IMI herbicides when used at their own or in combination with IMI herbicides.
Key messages
Balance® + simazine with or without Reflex® were equally effective for controlling wild radish and common sowthistle in chickpea compared to additional spray of IMI herbicide at trail site in 2023.
Intercept® (POST) application was found essential to control vetch in IMI tolerant pulses.
Metribuzin 380 g/ha (POST#) in GIA Metro (applied as per PVMA permit PER92810) provided effective control of wild radish, common sowthistle and vetch compared to the unsprayed control.
