Abstract
Fusarium moniliforme Sheld. conidia and vegetative
hyphae were capable of overwintering (1979 and 1980) without
any loss of viability or pathogenicity in grain sorghum
(Sorghum bicolor (L.) Moench.) stalks under Kansas conditions.
No structures such as thick hyphae, chlamydospores or sclerotia
were observed in 1979 although chlamydospore-like cells
were observed on some hyphae in 1980* Additionally, no loss
in viability of conidia or hyphae was observed when P.
moniliforme was stored at -16C for six months. This suggests
that low winter temperatures have no lethal effects on F.
moniliforme and also shows that special overwintering structures
are not essential for overwintering of F. moniliforme.
Fusarium moniliforme Sheld., described in 1904,
occurs in both tropical and temperate regions of the world
as a a pathogen or numerous crops (2). Chlamydospore production
has not been reported (2) although the fungus can be isolated
from overwintered host tissues (7, 10). The survival mechanisms
for overwintering in the temperate regions are unknown for
F. moniliforme.
Myvall and Kommedahl (9, 10) observed hyphae three
to four-fold thicker than normal F. moniliforme hyphae from
