- Test soil to monitor population changes in rotations and to determine RLN species and population density.
- Avoid consecutive susceptible crops in rotations to limit the build-up of RLN populations.
- Choose wheat varieties with tolerance to maximise yields when RLN are present.
- Choose rotation crops with high resistance ratings, so that fewer nematodes remain in the soil to infect subsequent crops.
- Root-lesion nematodes are species of Pratylenchus nematodes that feed on the roots of crops and can cause yield loss.
- The main RLN species in the Southern Region are Pratylenchus neglectus and P. thornei.
- The Pratylenchus species present in the soil will affect choice of management practices, in particular rotations.
- RLN have a wide host range and can multiply on cereals, oilseeds, pulses and pastures as well as on broadleaf and grass weeds.
- Root-lesion nematodes are found over 5.74 million ha (or ~65%) of the cropping area of Western Australia (WA).
- Populations potentially limit yield in at least 40% of these infested paddocks.
- The main species found in broadacre cropping in WA are Pratylenchus neglectus, P. quasitereoides (formerly known as P. teres), P. thornei and P. penetrans.
- The host range of RLN is broad and includes cereals, oilseeds, grain legumes and pastures, as well as many broadleaf and grass weeds.
