Abstract

Internal symptoms of Petri disease include brown wood-streaking and an abnormally dark pith, caused by Phaeomoniella chlamydospora (Pch). This paper reports on the effect of eight fungicides and a hot water treatment on naturally infected one-year-old Pinot Noir rootlings in a glasshouse trial. Vines were destructively assessed 22 weeks after planting. All treatments significantly reduced the incidence of dark pith. Phosphonate treatment was the most effective and benzothiodiazole was the least effective treatment with respect to controlling Pch. These results will contribute to the development of an integrated management program for grapevine propagating material.
