  Digging into soilborne disease

  Aug 16, 202624 minS3

  Soilborne diseases can be difficult to spot, but their impact on crop performance and yield can be significant. In this episode of Grains Convo, DPIRD researchers Daniel Huberli and Ahmed Saad discuss key soilborne diseases affecting WA crops, including rhizoctonia, crown rot and take-all. Learn what symptoms to look for, how to get an accurate diagnosis and the integrated management strategies that can help reduce disease risk.

  Understanding nematodes in WA grain crops

  Aug 6, 202620 minS3

  Not all poor performing crops are suffering from nutrient deficiencies or disease. In this episode of Grains Convo, Senior Research Scientist Sarah Collins explains how plant parasitic nematodes affect WA grain crops, why the symptoms are often mistaken for other problems and how growers can identify infestations early. Discover why digging up roots is just as important as inspecting crops from above, how diagnostic testing can guide management decisions, and the long term rotation strategies that help reduce nematode populations and protect yield.

  Early cereal disease: Making the right call

  Jul 14, 202622 minS3

  Young cereal crops are beginning to emerge, bringing the first signs of disease in some paddocks. In this episode, DPIRD Principal Research Scientist Geoff Thomas and Research Scientist Jason Bradley discuss the cereal diseases growers are most likely to encounter early in the season, how to distinguish disease from herbicide damage and other lookalike symptoms, and why careful monitoring and accurate diagnosis can help avoid unnecessary fungicide applications.
