Patchy emergence due to a few weeks of dry and then a rain, or due to reseeded crop emerging among the few original plants, has created a wide range of stages in some crops. Make herbicide timing decisions based on the stage that represents the highest proportion of plants. And rather than planning on two applications, growers may be better off spraying once at the highest registered rate when weeds that are more advanced than the crop, and with rapidly growing canola plants.
