Phenylamide-resistant isolates of Phytophthora infestans have gradually become an important part populations in many countries. However, fungicide mixtures containing a phenylamide component are still effective strategy for the control late blight potato and tomato. The proportion phenylamide-resistant fluctuates from year to within season. Almost concurrent with appearance resistant was discovery A2 mating type P. European countries other parts world. no genetic correlation exists between...
The cytochrome b (cyt b) gene structure was characterized for different agronomically important plant pathogens, such as Puccinia recondita f sp tritici (Erikss) CO Johnston, P graminis Erikss and Hennings, striiformis Erikss, coronata avenae Syd & Syd, hordei GH Otth, secalis Roberge, sorghi Schwein, horiana Henn, Uromyces appendiculatus (Pers) Unger, Phakopsora pachyrhizi Hemileia vastatrix Berk Broome, Alternaria solani Sorauer, A alternata (Fr) Keissl Plasmopara viticola (Berk Curt)...
Resistance to QoI fungicides in Pyrenophora teres (Dreschsler) and P. tritici-repentis (Died.) Dreschsler was detected 2003 France Sweden Denmark respectively. Molecular analysis revealed the presence of F129L mutation resistant isolates both pathogens. In 2004, frequency populations pathogens further increased. The G143A also a few from Germany. 2005, increased geographical distribution UK but remained below 2% Germany, Switzerland, Belgium Ireland. tritici-repentis, mutations were found...
To overview the gene content of important pathogen Phytophthora infestans, large-scale cDNA and genomic sequencing was performed. A set 75,757 high-quality expressed sequence tags (ESTs) from P. infestans obtained 20 libraries representing a broad range growth conditions, stress responses, developmental stages. These included infestans-potato -tomato interactions, which 963 ESTs were identified. complement ESTs, onefold coveragethe genome regions coding potential unigene 18,256 sequences...
Azole resistance is a concern for the management of diseases caused by Aspergillus fumigatus in humans. fungicide use environment has been identified as possible cause development resistance, which increases complexity and number stakeholders involved this emerging problem. A workshop was held Amsterdam early 2019 stakeholders, including medical agricultural researchers, representatives from government, public health, producers end-users, reviewed current evidence supporting environmental...
A total of 134 isolates Phytophthora infestans were collected from potato and 42 tomato fields in Switzerland France 1996 1997, compared with other countries. The structure the populations was analysed phenotypically genotypically, associated to geographical, seasonal host origin. Phenotype characteristics included mating type; sensitivity phenylamide fungicides; virulence on differentials; pathogenic fitness. Genotypes assessed for mitochondrial DNA haplotype restriction fragment length...
Field isolates of Mycosphaerella fijiensis, causing black Sigatoka banana, were characterised for their sensitivity to different inhibitors the cytochrome bc1 enzyme complex (Qo respiration inhibitors, strobilurin fungicides), using physiological, biochemical and molecular genetic methods. Strobilurin-resistant exhibited very high resistance factors both in mycelial growth inhibition NADH consumption assays. Cross-resistance was observed among all Qo including trifloxystrobin, azoxystrobin,...
Two methods for evaluating the joint action of fungicides in mixtures were analysed. In order to obtain a relatively rapid answer on type interaction between mixture (additivity, synergism or antagonism), one can apply Abbott formula data fungus survival. Tests with this method will not be accurate at high effective dose values. A more determination made by Wadley method, applied doses. This involves experimental work than method. Optimization mixing ratios required set doses several ratios.
Mandipropamid is a new mandelic acid amide fungicide expressing high activity against foliar infecting oomycetes, including the grapevine downy mildew, Plasmopara viticola . Because cross‐resistance with valinamide fungicides iprovalicarb and benthiavalicarb cinnamic dimethomorph flumorph was postulated, all five compounds are classified as carboxylic (CAA) fungicides. To support this classification, among these field isolates segregation of resistance in F 1 2 progeny P. were evaluated. A...
Abstract BACKGROUND: Pseudoperonospora cubensis, the causal oomycete agent of cucurbit downy mildew, is responsible for enormous crop losses in many species Cucurbitaceae , particularly cucumber and melon. Disease control mainly achieved by combinations host resistance fungicide applications. However, since 2004, to mildew has been overcome pathogen, thus driving farmers rely only on spray applications, including carboxylic acid amide (CAA) fungicides. Recently, CAA‐resistant isolates P....
The sensitivity of Venturia inaequalis field isolates to inhibitors the cytochrome bc1 complex at Qo site (QoIs) was characterised molecular, biochemical and physiological level, compared other respiration inhibitors. Comparison a sensitive QoI-resistant isolate revealed very high resistance factors both in mycelium growth spore germination assays. Cross-resistance observed among QoIs such as trifloxystrobin, azoxystrobin, famoxadone, strobilurin B myxothiazol. In assay, antimycin A, an...
