Root lesion nematode and crown rot double trouble!

摘要

Northern Grower Alliance has been involved in 22 field trials since 2007, in collaboration with I&I NSW, evaluating the impact of crown rot (CR) on a range of winter cereal crop types and varieties. This work has greatly improved our understanding ofcrown rot impact and variety tolerance, but it also indicates we may be suffering significant yield losses from another - often unnoticed - 'disease'. Although the trials were not designed to focus on nematodes, a convincing trend was apparent after 2008that indicated the root lesion nematode Pratylenchus thor-nei (Pt) was having a frequent and large impact on wheat yield.
