Sensitivity of Sclerotinia homoeocarpa to demethylation- inhibiting fungicides in Ontario, Canada, after a decade of use
In late 2003, nine populations of Sclerotinia homoeocarpa in Ontario Canada (seven of which had been previously sampled in early 1994, prior to the registration of sterol demethylation-inhibiting (DMI) fungicides for turf disease control in Canada) were sampled and tested for sensitivity to propiconazole. Four of the nine populations had not been treated with DMI fungicides during the interveni...
متن کاملNew rapid PCR protocols to distinguish genetic groups in Erysiphe necator
Introduction: Genetically distinct but morphologically similar groups of Erysiphe necator Schwein. (formally Uncinula necator (Schwein.) Burrill (BRAUN and TAKAMATSU 2000) have been identified in Europe, India (DÉLYE et al. 1997) and in Australia (STUMMER et al. 2000). One group reproduces only asexually and can thus provide well-adapted persistent clones, whereas the other group can also produ...

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 کاملMetrafenone 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 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...
