Abstract
In the present study, we investigated the effect of T. occidentalis L. leaves due to its fungicidal activity, therefore leaves extract as well as its whole powder form was taken to control Fusarium spp., Macrophomina phaseolina and Rhizoctonia solani. We found a significant increase in plant growth parameters when 1.0% w/v concentration of leaves extract was used as soil drenching, and seed treatment. Our data also indicated an increase in plant growth parameters when leaves powder was used as soil amendment at 0.5% w/w. We also found a measurable reduction in the colonization of root rot fungi. Although soil amended with 2.5% w/w leaves powder showed complete suppression in the colonization of pathogenic fungi, but failed to improve plant growth seems to be toxic to test plants as it ceased the germination and caused stunted and wilting symptoms were observed.
