Metrafenone resistance in a population of Erysiphe necator in northern Italy
BACKGROUND Metrafenone has been used in Europe in integrated pest management programmes since 2006 to control powdery mildews, including Erysiphe necator. Its exact mode of action is not known, but it is unique among fungicide classes used in powdery mildew management. Recently, resistance to metrafenone was reported in Blumeria graminis f. sp. tritici. In this study we investigated metrafenone...
متن کاملA method for refining and testing generalised machine specifications
Two current areas of emphasis in the development of methods for engineering higher quality and safer software are the use of formal methods for the specification and verification of software and the development of sophisticated methods of software and system testing. In general these two approaches are unrelated and few examples exist whereby the best aspects of both are used in an integrated w...

چکیده بیماری سفیدک سطحی انگور Erysiphe necator از لحاظ اقتصادی یکی از مهمترین بیماری های انگور در ایران و دنیا بشمار می رود و در صورت فراهم شدن شرایط مناسب خسارت قابل توجهی به تاکستان ها وارد می سازد. به منظور بررسی بیولوژی سفیدک سطحی انگور و عامل مولد مایه تلقیح اولیه در ایجاد اپیدمی آزمایشی در طی سال های 1389- 1387 در مشگین شهر انجام گرفت. بر اساس بررسی های انجام شده قارچ عامل بیماری به صورت...
متن کاملCharacterization of Erysiphe necator-Responsive Genes in Chinese Wild Vitis quinquangularis
Powdery mildew (PM), caused by fungus Erysiphe necator, is one of the most devastating diseases of grapevine. To better understand grapevine-PM interaction and provide candidate resources for grapevine breeding, a suppression subtractive hybridization (SSH) cDNA library was constructed from E. necator-infected leaves of a resistant Chinese wild Vitis quinquangularis clone "Shang-24". A total of...
متن کاملDetection of Erysiphe necator in Air Samples Using the Polymerase Chain Reaction and Species-Specific Primers.
ABSTRACT A polymerase chain reaction (PCR) assay employing species-specific primers was developed to differentiate Erysiphe necator from other powdery mildews common in the northwest United States. DNA was extracted from mycelia, conidia, and/or chasmothecia that were collected from grape leaves with a Burkard cyclonic surface sampler. To differentiate E. necator from other erysiphaeceous fungi...
