Current procedures for the characterization of fungal plant pathogens are generally based on morphological, biochemical, molecular or pathological techniques. Individual techniques have been used successfully in the characterization of pathogens at different levels, including definition of host and geographic ranges, and differentiation of subgroups within these. The methods used for the characterization of fungal plant pathogens generally fall into two groups, either‘genetic', i.e. based on traditional genetics, DNA sequences and polymorphisms, or‘functional', i.e. based on particular phenotypic activities such as secondary metabolism, enzyme activities or pathogenicity. Many of the modern genetic methods have been extremely useful in specific cases, although techniques such as DNA polymorphisms are not always suitable for subsequent diagnostic regimes. Integration of genetic techniques with functional characters can provide a very powerful tool for the characterization of fungal plant pathogens, particularly in respect of host and cultivar‐specific populations. Recent studies based around such an approach have included vascular wilt isolates of Fusarium oxysporum , and Rhizoctonia solani from rice.
