Flooding causes oxygen in the soil to decrease and not be available to the roots, resulting in oxygen deprivation. It is associated with compacted soil and low areas with poor drainage. Early season flooding may reduce and delay emergence, and promote stem rots, blackleg and stem/stolon canker. Mid- and late season flooding may reduce yields and increase mis-shaping of tubers. Plants in wet field areas are more susceptible to late and early blights. Tuber lenticels will enlarge, increasing the risk of bacterial soft rot, pythium leak and pink rot. Tubers harvested after late-season flooding do not store well and break down.
