The present study was conducted with the objectives to evaluate the efficacy of plant extract against leaf rust of diseases (Melampsora ricini). Botanicals were evaluated against rust disease on castor plants in greenhouse and field conditions at Melkassa Agricultural Research Center. The treatments were arranged with CRD for greenhouse and RCBD in the field experiments in three replications. Significant differences were observed among botanicals in the green house as well as field experiments. In green house, next to mancozeb maximum disease reduction (52 %) and fresh leaf weight (40gm) and dry leaf weight (8gm) were recorded from neem (Azadirachta indica). In field trial, among considered botanicals, minimum incidence (26.36%) and disease index (29.45%) were recorded from neem which was at par with garlic (33.33%), pyrethrum (40.56 %), lantana weed (47.22%) and mancozeb. Findings illustrated that the tested botanicals were effective for managing leaf rust of disease. Thus, they seem to be effective for the management of leaf rust and has the potential to be a vital component of integrated management for leaf rust of castor Melampsora ricini.
