Cropping options to limit root-lesion nematodes

Abstract

Australia’s northern grain-producing region is unique in that the root-lesion nematode (RLN), Pratylenchus thornei
predominates. P. neglectus is also present. RLN cause substantial yield losses, particularly in wheat, but they reproduce on numerous summer and winter crops. Each nematode species prefers different crops and varieties. This
project provides growers with a range of integrated management strategies to limit RLN (i.e. identify the problem, protect uninfested fields, rotate with resistant crops to keep populations low and choose tolerant crops to maximise
yields). It also provides new information about soil-borne zoosporic fungi in the region.
