Phosphonic acid applied as a soil drench, a foliar spray or a trunk injection before infection prevented the development of cankers in almond and cherry trees inoculated with Phytophthora cambivora. Foliar applications of 2 g phosphonic acid/L in autumn and spring were an effective and practical treatment. Trunk injections were also effectively but in some… (More)
Two shade house and six field experiments were undertaken to evaluate fungicides and timing of application for the control of pink rot of potatoes caused byPhytophthora erythroseptica. Pink rot developed in up to 60% of tubers grown in artificially inoculated soil and 21% of the tubers in naturally infected soil. Ridomil (metalaxyl) and Ridomil Gold… (More)
Collections of rust fungi (Pucciniales) on species of Allium in Australia have previously been identified as Puccinia allii. These identifications are unsatisfactory as P. allii is a species complex that has yet to be taxonomically resolved. Some of the cryptic species in this complex may represent new introductions and have potential biosecurity… (More)
Sclerotinia sclerotiorum was recovered from rotting grapevine shoots (Vitis vinifera) cv. Cabernet Sauvignon in a vineyard in South Australia in October 2000. The fungus was also detected in October and November 2001 in a further 14 vineyards in the cooler grape growing areas of South Australia, affecting Cabernet Sauvignon, Shiraz, Pinot Noir, Riesling,… (More)
Between 2000 and 2003 over 100 leek plantings and two nurseries in four states were surveyed to determine the most significant disease problems of leeks in Australia. Four diseases were identified causing economic loss: Fusarium foot rot (caused by one of four Fusarium species), bacterial blight (Pseudomonas syringae pv. porri), leaf blight (Stemphylium… (More)
Colletotrichum acutatum, the cause of anthracnose in almond, was recorded for the first time in South Australia in October 1996. The fungus was recovered from rotted nuts and dead sterns collected from almond orchards in the Southern Vales and Adelaide Plains areas of South Australia.
Pseudomonas syringae was recorded on olives (Olea europaea) for the first time in South Australia in March 2001 from a property approximately 30 km south of Adelaide, South Australia. The bacterium was recovered from sunken brown stem lesions on 2-year-old olive trees cv. Barnea. In the following season from December 2001, further infections were observed… (More)
Wilting, yellowing, and dying plants of Ixodia achillaeoides have been observed in commercial plantings in South Australia since 1990. Pathogenicity tests confirmed that Meloidogyne sp., Verticillium dahliae, Fusarium oxysporum, E tabacinum, Phytophthora cryptogea, P. erythroseptica, Oidium sp. and Botrytis sp. are pathogens of Ixodia. Pratylenchus sp. have… (More)
