Fungicide resistance - the Japanese experience

Uesugi Yasuhiko, . (1990) Fungicide resistance - the Japanese experience. [Proceedings Paper]

Occurrence of field resistance to fungicides in plant pathogens has been a problem in Japanese agriculture since 1971. The fungicide concerned had selective and specific action. The resistance mechanism may be mostly modification of the site of their action or the related site by spontaneous mutation. Reduced viability of resistant population in the absence of the fungicide in the field was observed in several cases. Countermeasure for the resistance problem is to avoid intensive and repeated use of a single group of fungicides. Development of fungicides of a different mode of action is also important. Novel fungicides having negatively correlated cross-resistance with an existing fungicide group are being developed

Abstract

Occurrence of field resistance to fungicides in plant pathogens has been a problem in Japanese agriculture since 1971. The fungicide concerned had selective and specific action. The resistance mechanism may be mostly modification of the site of their action or the related site by spontaneous mutation. Reduced viability of resistant population in the absence of the fungicide in the field was observed in several cases. Countermeasure for the resistance problem is to avoid intensive and repeated use of a single group of fungicides. Development of fungicides of a different mode of action is also important. Novel fungicides having negatively correlated cross-resistance with an existing fungicide group are being developed
