Powdery mildew has been detected in several mungbean crops growing in southern Queensland within the last couple of weeks.
Powdery mildew in mungbean is caused by the fungal species, Podosphaera xanthii and Erysiphe vignae. Two fungicide options are currently under permit to manage the disease, including tebuconazole products (PER13979 – download the permit from the APVMA portal for more details on use) and Veritas® Opti, which contains a mixture of tebuconazole and azoxystrobin.
The PowderyMildewMBM app is available to assist growers and advisors in making fungicide management decisions. DAF and UniSQ researchers currently have field trials underway to further validate the PowderyMildewMBM app.
Monitor crops closely for disease symptoms. Contact our plant pathologist, Lisa Kelly at [email protected] or 0477 747 040 for further information on disease diagnosis.
