Abstract
SUMMARYIsolates of Fusarium solani, F. solani var, coeruleum, F. oxysporum, F. oxysporum var. redolens, F. avenaceum, F. graminearum, F. sambucinum var. coeruleum and F. equiseti were obtained from field samples of Pisum sativum, Phaseolus vulgar is, P. coccineus and Vicia faba with foot‐rot symptoms. Their pathogenicity was tested in the glasshouse using artificially infested soiJ. All isolates originally identified as F. solani var. coeruleum and F. oxysporum var. redolens were later regarded as strains of F. solani on the evidence of their pathogenicity.Virulent isolates of F. solani from Pisum sativwn were also pathogenic to Phaseolus vulgar is but usually not to V. faba, although an isolate from V. faba was strongly pathogenic to Pisum sativum. Less virulent isolates from P. sativum, Phaseolus vulgar is and P. coccineus were generally equally pathogenic to both Pisum sativum and Phaseolus vulgar is. Isolates from Pisum sativum infected other legumes, particularly Trifolium pratense and Medicago sativa and an isolate from Trifolium sp. caused severe foot‐rot of P. sativum.Isolates of F. avenaceum, F. graminearum and F. sambucinum var. coeruleum showed non‐specific pathogenicity to P. sativum, Phaseolus vulgar is and V. faba, generally causing seedling death. F. avenaceum and F. sambucinum var. coeruleum were also pathogenic to other legumes, particularly M. sativa.
