How to diagnose root lesion nematode
Root lesion nematode is a significant broad acre crop issue in WA. It causes yield losses of up to 40 per cent and it is present in roughly 60 per cent of paddocks in WA. It is difficult to diagnose, so it's important to be aware of the key paddock and plant symptoms to correctly identify it. This clip gives an outline of these, as well as crop monitoring tips to help diagnose the constraint.
