Reaction of important phytopathogenic fungi to fungicides in laboratory biotests. 9th Internatioanl symposium on Septoria Diseases of Cereals
Popis výsledku v původním jazyce
Contribution on 9th Internatioanl symposium on Septoria Diseases of Cereals, 7-9 April, 2016, Paris, France, 2016, p. 87. An agar dilution method was used to determine the inhibitory effect and effective dose (ED50) of chosen fungicides on the main cereal fungal pathogens. 50 isolates of Microdochium nivale, 41 isolates of Oculimacula spp., 55 isolates of Zymoseptoria tritici, 54 isolates of Pyrenophora teres and 27 isolates of Ramularia collo-cygni were collected from wheat and barley across the Czech Republic in 2015. There were tested active substances from the fungicide groups QoI-strobilurins (picoxystrobin), SDHI (penthiopyrad) and imidazoles (prochloraz). 47.3% of Zymoseptoria tritici isolates, showed an increased level of resistance to strobilurins (ED50 > 0.5 µg.ml-1). 100% of Z. tritici isolates were fully sensitive to penthiopyrad (population ED50 = 0.04 µg.ml-1). M. nivale and Oculimacula did not showed an increased level of resistance to prochloraz (populations ED50 = 0.06 and 0.12 µg.ml-1 respectively). 16.6% of isolates Pyrenophora teres showed increased level of resistance to strobilurins. 100% of the isolates of P. teres were fully sensitive to penthiopyrad (population ED50 = 0.05 µg.ml-1). 44% of Ramularia collo-cygni isolates showed an increased level of resistance to strobilurins. Overall, the most serious situation is for Z. tritici and R. collo-cygni where the populations showed a significant level of resistance to strobilurins.
