@BoyesTim Vetch was a host for P. neglectus in glass house trials and we are testing it in a paddock which has Pquasi, Pneg and Rhizoctonia at Calingiri this year so watch this space...

DPIRD researchers Carla Wilkinson, Dominie Wright and Miriam Connor are putting out a request for plant samples from growers and agronomists, needed for national survey of root diseases and pests of pulses and legumes. Find out how you can help. https://t.co/93uCamYDow @GRDCWest

A new era for our plant disease & Soils teams @DPIRD_WA! We are investigating deep soil amelioration to reduce soil borne disease & plant parasitic nematode impacts @ Darkan & Yerecoin sites. Watch this space 😀 @GRDCWest #Nematodes #rhizoctonia

Meloidogyne fallax is also an issue for potato growers in the south west of Western Australia. Great photos of typical symptoms.

[Dr Bill Watts @Crop_Trials]

#RootKnotNematode tuber damage symptoms (#RKN - #eelworm). This was caused by #MeloidogyneChitwoodi in the Netherlands. The symptoms are the same as Meloidogyne fallax. Best to keep an eye out. #QuaratinePest. The brown spots indicate the location of mature females.

Potato roots with severe sting nematode infestation exhibiting short, pruned lateral roots. Parts of root system have few laterals others have small mats of proliferation. Compare with healthier potato roots that have long, evenly-spaced lateral roots (photo 2) #UFBugs

63 days after planting in hastings potato nematicide trial with severe sting nematode infestation. Both telone and nimitz treated potatoes have much more vigorous vine growth and row fill than untreated. #UFBugs

RLN susceptible chickpeas were used in diverse rotation. Chickpeas have now been replaced with lupins which should reduce RLN in the diverse rotation.

[Kylie Chambers @KylieRChambers]

Ken Flower from UWA looking at the effect of crop rotations on disease
- Window burning had little effect on soilborne diseases in the long term.
- Crown rot and rhizo ⬆ in cereal rotations while RLN and pythium ⬆ prevalence in pasture and diverse rotations

Trial to compare resistance of wheat, barley and triticale varieties to P. neglectus in western region with their resistance in the east. If similar then we can adopt their ratings.

Root lesion nematode (P. penetrans) activity is causing patches of chlorotic and stunted plants in canola at Chapman. Read about it in #PestFax @GRDCWest https://t.co/zcuRu7Tn3N

[DPIRD Broadacre - WA Grains & Livestock @DPIRDbroadacre]

A summit trial through @FaceyGroup. Root lesion nematodes found in initial soil samples – DPIRD providing expert advice & conducting RLN assessments on a number of treatments. https://t.co/29u93gSo5G

[Kylie Chambers @KylieRChambers]

@sarah_nematodes has shown using past research and glasshouse pot trials that serradella species are resistant to RLN.

Alan McKay from SARDI showing that root diseases are important & that even though the crop may look good up top, the root systems still may be being attacked by soilborne diseases.

Sean sampling P. penetrans mixed crop trial in Dandaragan. All crops increase P. penetrans but wheat and barley more resistant than canola and lupins #DAF_WA #theGRDC
