Abstract  Extracts of different algal samples were tested for different fungal population; it reveals that  cold water extract of algae showed antifungal activity.  Keywords: Algal Extract, fungi, cold water Extract INTRODUCTION       Algae are the very important group of plant kingdom, they occur in verity of habitats. Algae are now a days become very important constituents, they are important providers of a wide array of bioactive compounds including plant growth   regulators like gibberellin, auxin, cytokinin, ethylene, abscisic acid and jasminc acid [1]. Algae also content agar-agar, protein, vitamins and mineral etc. but the detail work belonging to antifungal activity is not carried out. Ten different algae, Chara grovesi Cladophora callicoma, Hydrodictyon, reticulatum, Nitella batrachosperma, Schizomeris leibleinis, Phormidium corium, Spirogyra plena, and Plectonima platensis were collected from different fresh water reservoirs of Marathwada.  It’s fine  powder was prepared and used for further investigation.  MATERIALS AND METHOD        The fine algal powder was prepared propane from the algae which were colleted from different sits. They had kept in air tight specimen bottle until use, extraction of algae was made in cold water. Antifungal activity of such algal samples was determined by using plant pathogens like Alternaria alternata, Aspergillus flavus, Fusarium roseum, Trichoderma harzianum and Curvularia  lunata, Bioassay was done in glucose nitrate (GN) medium.  In GN medium algal extract along with 1ml fungal spore suspension was added and kept for seven days after seven days of inoculation the mycelium was harvested and results are noted.  RESULTS AND DISCUSSION       The cold water extract of some algae shows stimulatory as well as inhibitory effect. The algal extract of Nitella batrachosperma, Spirulina platensis and Phormidium corium shows stimulatory property for Alternaria alternata, Aspergillus flavus and Fusarium roseum respectively, whereas the algal extract of Hydrodictyon reticulatum, schizomeris leibleinii, Spirogyra plena and Plectonema gracillimum shows total inhibitory growth against plant pathogenic fungi. Bernard et al (1989) [2] showed autibacterial and antifungal activity of extract prepared from the rhizomen to Mediterranean seagrass posidonia, also Composed et al (1988) [3] noted antimicrobial activity of marine algae from Brazilian northern. Coast Prashantkumar et al (2006) [4] recorded antimicrobial activity of blue green and green algae, Kulkarni (1993) [5] studied seven algae for its antimicrobial activity against Aspergillus flavus,  Aspergillus niger and Alternaria brasica.
