Abstract
Eleven species of Colletotrichum and Glomerella and 1 ssp. of Colletotrichum were inoculated into detached, ripening tomato fruit. Colletotrichum sp. 1, Colletotrichum sp. 2, C. coccodes, C. dematium, C. dematium var. truncata, C. destructivum, C. gloeosporioides, C. graminicola, C. trichellum, Glomerella sp., G. glycines and G. gossypii were pathogenic. C. falcatum and C. trifolii were nonpathogenic. In general, isolates of Colletotrichum sp. 1, C. gloeosporioides, C. dematium and G. glycines were most aggressive. Differences in virulence among isolates occurred within G. glycines, Colletotrichum sp. 1, and C. gloeosporioides, with the greatest variability occurring in the latter species. C. dematium var. truncata, C. graminicola, C. trichellum, G. glycines and G. gossypii are reported for the 1st time as pathogenic to tomato fruit.
