Internal seed-borne nature of Sclerotinia sclerotiorum and Phomopsis sp. and their effects on soybean seed quality

Internal seed-borne nature of Sclerotinia sclerotiorum and Phomopsis sp. and their effects on soybean seed quality

Phytopathology 62(11): 1261-1263

S. sclerotiorum was internally seedborne in 30 of 39 lots of Lee 68 seed from 6 states in 1969 and 1970, in 8 lots of Cutler seed from Ky. in 1971 and 1 of Beeson and 17 of Amsoy from Ill. in 1971. Germination and field emergence were reduced by more than 25% incidence in seed. Recovery of the pathogen from Lee 68 was reduced after storage at room temp. (c. 22 deg C) for 6 and 24 months compared with samples from the same lots stored at 3 deg for 18 months.
