Seed transmission, over wintering and survival of Pseudomonas syringae pv. glycinae on processing soybean were evaluated as well as the spread of the bacteria on alternative host and non-host plants. The bacteria were transmitted at a low rate from soybean seeds to the seedlings. Bacterial density in seeds obtained from systematically infected plants ranged from 110 to 115 cfu/g seed. Surviving bacteria associated with infested soybean debris were found in a higher number when debris was on soil surface compared to the buried debris. Population of the bacteria on alternative host and non-host plants ranged from 0 to 108 cfu/g fresh weight on leguminous plants and from 0 to 100 cfu/g fresh weight or: non-leguminous weeds. The bacteria were not detected in naturally infected soybean seeds when soaked in 0.5% Hcl for 5 hours, 0.25% or 0.05% acidified cupric acetate for 2 minutes or in hot water (50-55°C) for 20-30 minutes. Hot water treatment had significantly improved seed germination. Other treatments were ineffective in inhibiting the bacteria and have varied effects on germination.
