Abstract
The efficacy of maize varieties and Lambdacot 500EC concentrations were assessed on the damage caused by maize stem borer (Busseola fusca Fuller) (Lepidoptera: Noctuidae) on maize during 2015 and 2016 cropping seasons. The experiment was a split-plot design with Lambdacot 500EC concentrations (0.5 , 1.0 and 1.5 l/ha) as the main plots and three maize varieties (SAMMAZ 14, DMR-LSR-Y and BR9943-DMR-SR-W) as the sub-plots on a plot size of 3.0 m x 4.0 m replicated three times. Maize plants were sprayed with the different Lambdacot 500 EC concentrations at 4 and 6 weeks after planting (WAP) The results obtained showed that lowest number of maize plants with leaf sheath pin-holes, dead hearts, and stem tunnels and cobs damage by larvae were recorded on SAMMAZ 14 and DMR-LSR-Y while BR9943-DMR-SR-W had the highest. Maize plants treated with Lambdacot 500EC at 1.0 l/ha and 1.5 l/ha had lowest leaf sheath pin-holes, dead hearts, stem tunnels ...
