The present investigation was commenced in 1932 and has been continued annually since that time with the object of determining the identity, host range, and geographic distribution of the Fz~sarizr?n species in Canada. Approximately 9000 isolates of Fzrsarizr?tz were studied. These isolates were obtained from 173 species and botanical varieties of plants, 14 species of insects, and 4 of fungi. Of the varlous specles and botanical varieties of plants from which isolates were obtained, 19 were cereals and grasses, 19 were vegetable crops, 15 were fruit crops, 13 were field crops, 52 were ornamental plants, 31 were trees and shrubs, and 24 were common weed plants. Less than 1 % of the total isolates \was obtained from insccts and fungi. Hltho~igh most of the isolates originated in Manitoba, some were obtained from each of the other provinces of Canada except Newfoundland.

“…The predominance of F. oxysporum in our samples agrees with other reports, which indicate that this species is the major pathogen of the fungal flora. For example, Gordon (1956) found that F. oxysporum was by far the most prevalent species of Fusarium spp., as it represented approximately 67% of Fusarium spp. In Canadian soil, Gordon (1956) showed that the relative abundance of the F. oxysporum might reach 3 -10% of the soil total fungal population.…”

Fusarium species are known to play a role in several diseases of cotton including the seedling disease complex, wilt, and boll rot. Therefore, a mycoflora study was conducted in 1998 in order to identify Fusarium species found in association with cotton roots. A total of 109 samples of cotton seedlings infected with post-emergence damping-off or rotted roots of adult plants were obtained from different cottongrowing areas in Egypt. Forty-six isolates were recovered and were identified

“…suggested that F. graminearum was unlikely to survive in soil without crop residues. Sutton (1982) indicated that soil is unlikely to be a 'major inoculum source' and referred to work by Gordon (1954Gordon ( , 1956 in Canada, where F. graminearum was not isolated from soil samples collected from cereal fields. In Australia, Wearing & Burgess (1977) isolated F. graminearum Group 1 (now known as F. pseudograminearum) from soil, but mainly associated with small pieces of debris.…”

Fusarium species, which are typically associated with fusarium head blight of cereals, were isolated, identified and enumerated from residues collected in 239 cereal, 71 corn and 201 grass fields/sites in Alberta from 2001 to 2004. Cereal and grass residues were collected in the Peace River, central and southern regions of Alberta, while corn samples were collected from central and southern Alberta. The most frequently recovered species were F. avenaceum and F. culmorum followed by F. pseudograminearum and F. graminearum. Outside of southern Alberta, the most important causal agent of fusarium head blight, F. graminearum, was isolated at low levels in only one of 163 cereal fields, and was not isolated from the 39 corn fields or 105 grass sites surveyed. In contrast, in southern Alberta, F. graminearum was isolated from cereal residues in 10 of 76 cereal fields. Relatively high levels (46-50%) of node and crown infection occurred in one southern Alberta field in 2003. Fusarium graminearum was most common in corn residues from southern Alberta, being isolated from 24 of 32 fields, with average incidences of node infection ranging from 10 to 60% within these fields. In contrast, only three of 96 grass sites in southern Alberta had detectable, albeit low, levels of F. graminearum. The infrequent occurrence of F. graminearum, especially in central Alberta, and the Peace River region, suggests that Alberta's agricultural industry should continue to monitor its presence in grain and crop residues, while attempting to limit further build up and spread of this pathogen.
