Abstract
As according to ancient Vedic rites, Indians perform ‘Hawan’ every day to purify the atmosphere. Laboratory tests were conducted by exposing petriplates containing czapek dox agar medium, in a closed room, before and after fumigating ‘Hawan samagree’ and plant parts (dried leaves, bark, sawdust) ofMangifera indica, Azadirachta indica andSantanum album. Results showed considerable decrease in concentration of fungal load. This method can be successfully implemented at actual work places like small flour mills, ginneries, cobbler shops etc., to curtail the concentration of lethal fungi likeAspergillus, Penicillium, Alternaria, Curvularia, Cladosporium etc.
