With pre-emergence herbicides such as Sakura® or Firebird® having only recently been applied to wheat crops, it might seem strange to be thinking about spring grass w**d control. But effective control of grass w**ds, especially ryegrass, requires a follow-up post emergence herbicide to be applied to prevent spring-germinating grass w**ds from becoming established.
This is where Othello® OD steps in. Apply Othello OD in late winter or early spring to wheat* when germinating grass w**ds can be seen to control a range of grass w**ds, especially ryegrass, and help your wheat crops deliver their full yield potential.
With the very dry conditions experienced in Canterbury during this autumn, pre-emergence herbicides could take time to activate. But grass w**ds still germinate. Applying Othello OD can control these grasses before the pre-emergence herbicide kicks in. (*Othello OD should not be applied to durum wheat or barley).
