Comparing double knock and individual herbicide treatments on flaxleaf fleabane (NSW pot experiment 2015)

Abstract

Key findings • Double knock applications of some group H containing herbicides followed by paraquat seven days later appear to be a viable alternative to double knocking with Tordon® 75D followed by paraquat for the control of early flowering flaxleaf fleabane. • The most effective group H containing herbicides in combination with paraquat as double knock treatments were Precept®, Balance® and Velocity® in order of effectiveness of their control of early flowering flaxleaf fleabane.
