Pink Eye

Pink patches develop around the bud
end and eyes The pink discolouration
is usually skin deep
If humidity is high soft rot
bacteria may invade affected
areas

Pink Rot

Infected areas appear dark brown to purplish
black The margin of the decay is often limited
by a dark line Infected skin is easily rubbed off
The internal rot usually begins at the stem end and is cream to light brown The rot has a texture similar to that of a boiled potato When
infected tubers are cut the flesh turns pink in
about 20 minutes and with time turns black
