dc.description.abstract | According to a survey conducted in 5 districts
in Kenya during the period 1982/83, many fungi were
associated with maize grains. These fungi were
found to have adverse effects on gralns as feed and
seed. Fusarium and Penicillium ~ were found ln
all samples and Aspergillus ~ in 80% of the
samples. Septoria maydis was also observed in one
sample from Nakuru. Most of the fungi observed
caused percent infection below 10% except Penicillium,
Aspergillus and Fusarium ~ whose level of
infection were 24.3%, 17.2% and 16.4% respectively.
Diplodia maydis and Septoria maydis were found
on dark-brown dead seeds. Fusarium moniliforme were
isolated from 80% of the samples and hindered
germination in pink seeds, while in others it caused
blight and root-rot. High infection at the hilum of
the seeds by Penicillium oxalicum killed the seeds.
Cephalosporium acremonium was isolated from seeds
which were dark-brown at the hilum.
Samples from Meru had high infection by
Aspergillus ~E£ and environmental conditions were
ideal for aflatoxin production. On TLC analysis
these grains yielded 65 ~g/kg total aflatoxin.
Application of the f un gi.c i des Captan and Fernasan
D effectively controlled most of the fungi without
serious side effects. Benomyl eradicated all
fungi but caused phytotoxicity to young seedlings. | en |
