This research detail the growing inhibition effect on Coniophora puteana and Trametes versicolor fungi caused by hot water sawdust and bark extracts of three semi-arid land species Condalia hookerii, Ebenopsis ebano and Helietta parvifolia diluted in malt extract agar medium at 2000 ppm and 10000 ppm. After 12-14 days incubation the inhibition growing effect was measured based on the difference between extracts and the control (fungi growing in malt extract agar medium without-extract). The highest growing inhibition was obtained from the fungi Trametes versicolor on malt extract agar medium from bark water extracts of Helietta parvifolia at 10000 ppm concentration. The second highest growing inhibition was amounted to 45 ± 12 for Trametes versicolor at the same species from sawdust water extracts.
