Effect of harvesting and storage conditions on infection of potatoes by Erwinia carotovora

Kartoffelbau 42(12): 474-480
Effect of harvesting and storage conditions on infection of potatoes by Erwinia carotovora
Potato tubers were harvested under different soil moisture conditions, dried or dipped in water or a suspension of E. carotovora, and stored under various conditions of temp. and RH. Half of each treatment group was also mechanically injured. Observations made on subsequent infections and on lenticel appearance suggested that the probability of infection increases with increasing numbers of bacteria on the tuber surface, and that open lenticels and wounds provide points of entry.
