Tomato is economically important horticultural crop worldwide, especially in Pakistan. Rhizoctonia solani is a serious threat for tomato growing areas, responsible for considerable crop and yield losses. This study was designed to minimize these huge economic losses and to regain the attention of formers which was shifted towards other crops as compare to this profitable crop. Leaves extract of three medicinal plants, cinnamon (Cinnamomum verum), moringa (Moringa oleifera) and clove (Syzygium aromaticum) were investigated against R. solani causing damping off of tomato. Three different concentrations (1%, 2% and 3%) were used to check the efficacy of plant extracts. Three different trials were conducted as invtro under CRD, greenhouse and field under RCBD.  Antifungal potency test showed that the maximum growth inhibition was observed at 3% concentration followed by 2 and 1% of each plant extracts. In vitro clove leave extract shown highest antifungal activity which causes complete mycelial inhibition 3% concentration. At 3% concentration efficacy of plants extracts was also examined on disease incidence as well as plant growth development in greenhouse and field experiment. Clove leave extract at 3% concentration recorded highly significant in disease reduction and other plant growth parameters. Thus, clove leaves are best choice for managing R. solani associated with damping off disease of tomato.
