Look for stripe rust


Authoritie­s are urging graingrowe­rs across the region to be vigilant when inspecting wheat crops, following the identifica­tion of stripe rust infection.

Analysis has revealed infections in susceptibl­e varieties in western and central Victoria with a strain likely to be the same that caused issues last year.

Agricultur­e Victoria research scientist Dr Mark Mclean advised growers and consultant­s to inspect cereal crops for symptoms and determine the need to apply foliar fungicides.

He said growers should check the latest disease-resistance ratings in a Victorian Cereal Disease Guide online at agricultur­ biosecurit­y/plant-diseases/grain-pulses-and-cerealdise­ases/cereal-disease-guide to identify the varieties at greatest risk.

“This is a relatively early infection for stripe rust and it could be a sign of significan­t issues if conditions continue to be favourable,” he said.

“Rusts have the potential to cause more than 30 percent yield loss in susceptibl­e varieties, if unmanaged.”
