Lentils - disease management, MRZ Yorke Peninsula locations
Aims
  • To test under field conditions, the susceptibility and disease reactions of commercial lentil varieties and advanced breeding lines when inoculated with ascochyta lentis isolate collected from PBA Flash in a high intensity lentil growing region in SA.
Key messages
  • The AB isolate caused a moderately susceptible disease reaction in unprotected (Nil) plots on varieties which are currently rated as being MR (PBA Blitz) and MR/MS (Nipper, Nugget and PBA Greenfield) which indicates a change in virulence of the AB isolate resulting in a loss of foliar AB resistance in these varieties.
  • Research conducted by SARDI Pathology group and reported elsewhere (Pulse Diseases 2017, GRDC Updates 2017 proceedings) has shown that the AB isolate tested in the current trial, caused susceptible reactions in PBA Hurricane XT and disease reactions in PBA Ace and PBA Bolt when tested under controlled environmental conditions. This results were however not confirmed under field conditions in the current trial.
  • The current results suggest that there is a change of virulence in the AB pathogen which may be causing a loss in foliar resistance on varieties currently rated as being relatively resistant. The AB isolate tested was collected from the high intensity lentil producing area in the Yorke Peninsula region in SA.
  • Protection of the plant foliage through application of fortnightly Chlorothalonil significantly increased yield in the most susceptible variety, PBA Flash (76 %) over unprotected (Nil) plots.
  • Grain yields were also improved in varieties that had moderate disease reactions together with those varieties that showed no disease symptoms, indicating the importance of fungicide sprays in not only controlling disease but also enhancing plant growth.
  • All commercial lentil varieties should be managed as having potential for risk from foliar AB especially under favourable conditions that promote disease. Varieties will need close monitoring for disease during the growing season and strategic fungicide sprays will be required in all varieties even in the absence of disease symptoms particularly in varieties rated as having foliar resistance to AB pathogen.
