Descripción:	The changes in fungicide resistance frequency of the rice blast fungus Magnaporthe oryzae were monitored by examining an assembly of 60 isolates collected over a period of 25 years in conventional growers´ rice fields. Initially, the in vitro sensitivity of all isolates to fungicides Azoxystrobyn, Tryciclazole, Trifloxystrobin+Tebuconazole and Tebuconazole was measured. Over the 25-year (1989-2014) time frame, a gradual rise in the EC50 estimates for mycelial growth sensitivity was observed for all fungicides, but most strikingly for Azoxystrobin.
