FLOODING 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.
