To establish a baseline using bioassay procedures, a reliable technique must be developed. The technique must also be able to be used in subsequent monitoring operations investigating possible development of resistance. If and when resistance develops, the same method may be used to identify resistant isolates, but it is possible that more specific methods will have been developed at that time.
In a joint effort to create standardized methods, members of different FRAC Working Groups have reviewed and collected detailed, ready-to-use bioassay techniques to monitor fungal pathogens of economic importance.
The following requirements were considered while establishing these techniques:
