Abstract

The genus Fusarium has a cosmopolitan distribution with representatives occurring in most parts of the world. Individual species may have more restricted distribution, often being confind to particular climate. This survey was undertaken in five areas with a range of climates in south eastern. New South Wales, Australia. Soil samples and plant debris were collected from 4 to 8 sites of each area. Fusarium species were isolated from all soil samples and plant debris using the dilution plant technique and debris plating technique respectively. Selective media (Pepton PCNB Agar=PPA) and Carnation Leaf Agar (CLA) were used for growth of the cultures. Plates were incubated in controlled conditions with alternating temperature regime 25ºC day and 20ºC night with a 12hr photoperiod. Twenty one species of Fusarium were isolated from soil and plant debris. The cosmopolitan species F. solani, F. oxysporum and F. equiseti were recovered from all areas, F. compactum and F. nygamai from the warmest area (Lake Cargellingo), while F. crookwellense. F. culmorum. F. tricinctum and F. sporotrichioides recovered only from the coolest area (Batlow). F. sambucinum was recovered most frequently from cool areas. F. proliferatum. F. chlamydosporum, F. graminearum and F. scirpi were isolated from moderate to warm areas, whereas F. anthophilum. F. lateritium. F. merismoides and F. babinda tended to occur in wet temperate areas near the coast. Species such as F. acuminatum F. aveanceum and F. semitectum did not show distinctive patterns in their distribution within the region surveyed. This survey has Fusarium species continued an empirical association between climate and distribution of Fusarium species.
