Identification of the causal agent of Botryosphaeria
stem canker in Ethiopian Eucalyptus plantations.
Disease assessments included measures of stolon pruning and
stem canker [22] made on three sequential assessment dates, 40, 55, and 70 days after transplanting.

Stem canker, Black scurf, animal manures.
The result obtained from present study showed that [beta]-1, 4 glucanase and chitinase may be involved in the enhanced resistance against
stem canker disease caused by B.
harzianum, at the time, 20 and 40 days after sowing revealed the lowest
stem canker index of 36.10% followed by treatment 4, in which an additional dose of T.
"Although
stem canker infects plants early in the growing season, symptoms--brown lesions on the stems--appear much later," says Tyler, who is also in the Stoneville unit.
Both S99-11509 and S99-11986 are resistant to
stem canker [caused by Diaporthe phaseolorum (Cooke and Ellis) Sacc.
"In almost every case, varieties doing noticeably better this season are those with the best
stem canker resistance.
N54 and N55 are biennial lines that are homozygous for susceptibility and resistance, respectively, to
stem canker (gooseneck) disease [caused by Ascochyta caulicola (Laub.)].
Registration of N30-N56, N741, N743, N745, N747, U362, U363, U367, U369-U374, U389-U394, U396-U398, and U500 sweetclover genetic stocks He said: "While the cold weather may delay the progression of the disease, shocking levels of phoma [canker] in susceptible varieties will also need careful management if
stem canker is not to compromise their yield and standing ability.
S99-3181 is susceptible to
stem canker [caused by Diaporthe phaseolorum (Cooke and Ellis) Sacc.
NKBravour demonstrates several other performance advantages; a rating of seven for stem stiffness at harvest, an eight for resistance to lodging at flowering and a seven for shortness of stem, allow for flexibility in the approach to canopy management and an easier harvest; and a broad spectrum disease resistance, in particular for
stem canker with a rating
