Root-lesion nematode

Root-lesion nematodes (RLN) are an important pest of broadacre crops. Yield loss is directly related to the population density at the time of sowing. Species in broadacre cropping include Pratylenchus thornei, P. neglectus, and in WA only: P. quasitereoides (also known as P. teres). The first step in managing RLN […]

Don’t rely on fungicides for net blotch and septoria

Nick Poole, Foundation for Arable Research (FAR) Australia talks about fungicide resistance at the GRDC updates in Adelaide, February 2015. He warns not to rely on fungicides to control Net Form of Net Blotch (NFNB) and Septoria tritici Blotch (STB). Use an Integrated Disease Management (IDM) package to prevent pathogen […]

BWYV: Reducing aphid and virus risk in 2015

In 2014, canola crops across SA, western Victoria and some parts of NSW were severely affected by beet western yellows virus (BWYV) (synonym; turnip yellows virus). Significant rainfall over much of the southern cropping zone in January 2015 has initiated a green bridge, which has the potential to host large […]

Charcoal Rot in Lupins

Charcoal rot was confirmed in a number Western Australian lupin crops in 2014 (DAFWA Pest Fax newsletter, No. 20); a likely consequence of the hot and dry conditions experienced during August. Normally charcoal rot does not reduce lupin crop yields as symptoms only appear after pod set. However, unseasonable heat in […]

Ascochyta blight – chickpea isolate survey

Dr Rebecca Ford

Dr Rebecca Ford from The University of Melbourne, discusses the survey of isolate pathogenicity in Ascochyta blight in chickpea. She describes the recent discovery of isolates that are more pathogenic on varieties such as HatTrick and Genesis 090, and how these isolates will contribute to developing Ascochyta resistance within the […]

Loose smut in Hindmarsh barley

Increasing incidences of loose smut infections in Hindmarsh barley crops in South Australia and Western Australia has prompted investigation into the effectiveness of seed treatments in controlling the disease, particularly in susceptible varieties. Observations made by the South Australian Research and Development Institute (SARDI) pathology team over the past three […]
