A slight
increase in the count of Trichoderma was observed when
stored in cassava thippy and cassava leaf powder, sawdust
and talc maintained the population, while a decrease in
cfu was obtained with cassava seed oil initially for three
months. Meanwhile this antagonist started to lose their
viability drastically (cfu < 106) when formulated on
cassava thippy after the sixth month of storage followed
by the other carriers (sawdust, cassava leaf powder and
talc) after nine months of storage.
