Aoki, Y., Kawagoe, Y., Fujimori, N., Tanaka, S., and Suzuki, S. 2015. Monitoring of a single point mutation in the PvCesA3 allele conferring resistance to carboxylic acid amide fungicides in Plasmopara viticola populations in Yamanashi prefecture, Japan. Plant Health Progress doi:10.1094/PHP-RS-140041. The use of the carboxylic acid amide (CAA) fungicide mandipropamid to manage grapevine downy ...
Hollomon D.W. (2015): Fungicide resistance: facing the challenge. Plant Protect. Sci., 51: 170–176 Fungicide resistance continues to generate disease control problems in many crops. Experience amassed over the past fifty years has emphasised the importance of diversity in modes of action in anti-resistance strategies. Because of losses, not only from resistance, but increasingly from environmen...
Three fungicide-sensitive Monilinia fructicola isolates were exposed in weekly transfers of mycelia to a dose gradient of a DMI and a QoI fungicide (azoxystrobin) in solo or mixture treatments and fungicide sensitivity as well as genetic changes were assessed. Isolates showed a faster reduction in sensitivity (higher resistance factors) to azoxystrobin than to SYP-Z048; this process was slower ...
Title of Document: INTEGRATED PEST MANAGEMENT OF FUSARIUM HEAD BLIGHT IN SOFT RED WINTER WHEAT. Elizabeth Reed, M.S., 2011 Directed By: Associate Professor Arvydas Grybauskas, Department of Plant Sciences and Landscape Architecture Fusarium head blight (FHB), caused by Fusarium graminearum, is a destructive disease of the soft red winter wheat grown in the Mid-Atlantic region. Management of FHB...
Filamentous ascomycetous fungi possess many histidine kinases and two conserved response regulators, Ssk1p and Skn7p, in their two-component signaling systems. We previously reported that the fungus unique group III histidine kinase regulates high-osmolarity adaptation and iprodione/fludioxonil fungicide sensitivity by controlling the phosphorylation of Hog1-type mitogen-activated protein kinas...
Black Sigatoka or black leaf streak disease, caused by the Dothideomycete fungus Pseudocercospora fijiensis (previously: Mycosphaerella fijiensis), is the most significant foliar disease of banana worldwide. Due to the lack of effective host resistance, management of this disease requires frequent fungicide applications, which greatly increase the economic and environmental costs to produce ban...
Chemical management of dollar spot in turf may lead to the development of Sclerotinia homoeocarpa populations with reduced fungicide sensitivity. The objective of this study was to investigate resistance of S. homoeocarpa isolates to triazole fungicides and to test cross-resistance among three triazole fungicides. A total of 66 isolates of S. homoeocarpa were collected from 15 golf courses acro...
Host resistance and synthetic antimicrobials such as fungicides are two of the main approaches used to control plant diseases in conventional agriculture. Although pathogens often evolve to overcome host resistance and antimicrobials, the majority of reports have involved qualitative host - pathogen interactions or antimicrobials targeting a single pathogen protein or metabolic pathway. Studies...
dry bubble disease is one of the most important serious diseases of the cultivated white button mushroom (agaricus bisporus (lange) imbach). it is a cosmopolitan disease having a worldwide distribution. ten isolates of lecanicillium fungicola var. fungicola (preuss) zare and gams were collected from mushroom farms. sensitivity of the isolates to benomyl, carbendazim, carbendazim+iprodione and p...
