ABSTRACT

Six commercial biopesticides like, dk-bioneem (0.1 and 0.2%,) multineem (0.01 and 0.03%), neem oil (0.5 and 1.0%), azacel (0.01 and 0.03%), calpaste (0.02 and 0.04%) and larvocel (0.05 & 0.1%) were evaluated against Dicladispa armigera in the field conditions. Five replications were followed for each treatment and each replication consists of four hills (25cm × 25cm area). Control (water spray) was also run against treatment. All the biopesticides showed effective reduction of the pest. However, highest mortality was obtained by Azacel (@0.03%) after 5 days of treatment but Larvocel (@0.1%) caused 86.36% reduction of hispa population after 10 days of treatment
