1) Improve herbicide rotation strategies with the focus on reducing selection pressure and dependence on IMI herbicides
2) 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, and cost analysis of these practices
• Following a non-IMI strategy in chickpea (Reflex® 750 ml/ha (IBS) + Balance® 100 g/ha (IBS) f.b. Simazine 800 g/ha (PSPE)) was equally as effective for controlling wild radish and common sowthistle as the same strategy with an additional spray of IMI herbicide.
• Following a non-IMI strategy in lentil (Reflex® 750 ml/ha (IBS) f.b. metribuzin 180 g/ha (PSPE)) proved equally as effective for controlling wild radish and common sowthistle as with the same strategy with an additional spray of either diflufenican or Intercept.
• IMI application was found essential to control vetch in both chickpea and lentil.
