ABSTRACT
A field trial was
conducted at the research farms Michael Okpara University of Agriculture
Umudike, Abia State, South Eastern to evaluate the effect of selected botanicals
on maize Leaf Spot and Streak Diseases in humid Umudike, South Eastern Nigeria
in a Randomized Complete Block Design (RCBD) with six treatments and three
replicates. The objectives of the study were to: determine the disease severity and percentage
incidence of maize leaf spot and streak diseases in humid Umudike, determine
the efficacy of the selected botanicals on maize leaf spot and streak diseases
and compare the effect of different selected botanicals on growth parameters
and grain yield in the study area. Maize leaf spots and streak diseases were
identified with a modified scale of Opera and Wokocha (2008) which were the
major threat to maize crops amongst smallholder farmers in the study area,
causing millions of losses annually. Cicadulina
mbila were detected as the main
vector of MSV. In addition to maize streak, the virus also infects wild
grasses. Results obtained from the field
experiment showed that the selected botanicals assessed reduced disease
incidence and severity drastically at 5% probability when compared with the
untreated (control). From the findings, the
results reviewed that combination of Virat and Nutrimax reduced the incidence
of maize leaf spot and streak diseases at (21.78%) as well as severity of leaf spot
and streak diseases at (0.66%) (P> 0.05). It means that the selected
botanicals were ecofriendly and cheap source of biopesticides in the management
of maize leaf spot and streak diseases.
