Bio-efficacy of Second Generation Anticoagulant Rodenticides in Pearl Millet - Moong - Moth Bean Cropping System in Indian Arid Region

Field efficacy of three second generation anticoagulant rodenticides was evaluated in pearl millet-moong-moth bean cropping system under arid ecosystem for the two crop seasons. The efficacy of all the three rodenticides was assessed by three methods viz., live burrow count, census baiting and trapping methods simultaneously before and at 4 and 14 days after treatnment. Control success after two weeks of treatment with (0.0025%) difethialone, (0.005%) bromadiolone and (0.005% brodifacoum was 85.1, 85.1 and 82.1% at vegetative growth stage and it was 87.5, 89.0 and 88.8% at maturity stage, respectively. Second treatment of respective anticoagulant rodenticides yielded higher control success due to mortality of residual pest population. No significant difference was observed between treatments, methods and blocks and all treatments proved equally efficacious in containing field rodents.
