Webinar Series: Pre-ems provide punch to prevent weeds
In our first webinar of this series, we ask Mark Congreve from ICAN Rural the question: why do things go wrong with pre-ems? Herbicide choice and farming system are factors to consider, with crop safety being top of mind. Mark takes us through the strategies to maximise pre-em performance particularly in relation to controlling ryegrass, wild oats, fleabane and sowthistle in the north and discusses how pre-ems breakdown and the implications on plantbacks and rotational crops. Scenarios in the northern region that lead to herbicide failure are discussed, as well as strategies to mitigate risk.
