LIVING WITH CROWN GALL:The following is a series of photos taken in mid-January,
2001. A block of 25 Sangiovese vines planted in 1994 showed poor
growth compared to the neighboring blocks. All have some level
of crown gall damage and on-going disease presumably magnified
by the continuing stress of crown gall. Symptoms included,
poor fruiting cane growth, signs of Eutypia , black goo-like
excretion from pruning wounds, discoloration within the vasculature
and V-shaped indentations on the older trunks and canes.
The vines however continue to put out renewal canes and/or respond
to pruning out of the infected wood.
