Abstract | More than 80 diseases have been recorded on soybean (Glycine max) in Australia, and of these only a handful can be considered to have had a significant impact on commercial crops. Charcoal rot (caused by Macrophomina phaseolina), sclerotinia stem rot (Sclerotinia sclerotiorum) and phytophthora root rot (Phytophthora sojae) are the most important root and stem pathogens, whilst rust (Phakospora pachyrhizi) can be considered to be the worst foliar pathogen. Losses from these endemic diseases can be effectively managed through Integrated Disease Management strategies, including plant resistance, paddock selection, optimum planting density and timing, and in the case of rust, timely fungicide sprays. At least 17 pathotypes of Phytophthora sojae have been recorded in Australia, and overseas several pathotypes of Phakopsora pachyrhizi are known. New pathotypes of these pathogens will appear when soybean varieties with a single gene for resistance are grown in regions and years favourable for disease development. Prior to 2012 powdery mildew (Erisyphe diffusa) had not been recorded in Australia, although there is evidence that the pathogen had been present before then. The disease's potential future impact on production is unknown. |
