Studies on Chemical Control of the Stem-Borers of Maize
Abstract
Between 196 and 1965 eight insecticides were tested against the stem-borers of maize in Ibadan. none of these insecticides was found to be oustanding but Carbaryl, both as dust and wettable powder was recommended for the control of stand loss due to stem-borer infestation on late maize. No statistically significant increases in yield were, however, obtained in both early and late crops probably because of the usually low infestation level on the early crop and the usually low fertility and moisture conditions during the late season
