Abstract: In the present investigation fungi-toxic properties of leaf extracts of five herbaceous wild plant species namely; Ageratum conozoides; Blumea erianth; Chrozophora rottleri; Galingsoga parviflora and Phyllanthus niruri were evaluated in vitro against two phyto-pathogens viz. Alternaria solani and Rhizoctonia solani. Leaf extracts were prepared in three solvents i. e. Ethenol; Methanol and Hot water. Extracts of Ageratum conozoides and Chrozophora rottleri; showed complete (100 %) mycellial inhibition of A. solani as well as R. solani at 10 % concentration which was comparable with respective fungicide at 100 ppm. Irrespective of plant species; extracts prepared in ethanol was most effective in arresting the mycelial growth of the pathogens whereas; superior phytotoxic activity was observed in Ageratum conozoides extracts and other four plants toxicity was found in corresponding manner - Chrozophora rottleri > Galingsoga parviflora > Blumea eriantha > Phyllanthus niruri.
