Survival of the pathogenic seedborne fungi in green pea seeds (Pisum sativum L.).

The seed microflora was examined of 758 seed lots of green pea sowing material harvested in Poland during 1966-84 and 35 seed lots stored for 25 to 88 months in the lab. under controlled conditions. Fusarium oxysporum f.sp. pisi, F. solani f.sp. pisi, Ascochyta pisi, A. pinodes [Mycosphaerella pinodes], Phoma medicaginis var. pinodella, Alternaria alternata, F. poae, F. sporotrichioides, F. sambucinum [Gibberella pulicaris], F. culmorum, F. avenaceum [G. avenacea], F. equiseti, Sclerotinia sclerotiorum, Botrytis cinerea and Rhizoctonia solani were identified in infected seeds. During storage, pathogenic fungi disappeared completely. Fusarium disappeared first, 2-3 years after harvest, followed by A. alternata, R. solani, B. cinerea and S. sclerotiorum 3-4 years after harvest. Ascochyta spp. survived longer and caused up to 37% infection. R. solani and B. cinerea survived in seeds for 38 months, S. sclerotiorum 46, Fusarium spp. 55, Ascochyta spp. 95 and A. alternata 106 months.
