| description | Cyanobacteria are gaining significant importance as potential biocontrol agents against phytopathogenic fungi. We evaluated the inhibitory effects of a suspension of <i data-eusoft-scrollable-element="1">Nostoc</i> sp. BCAC 1226 on <i data-eusoft-scrollable-element="1">Penicillium</i> sp., <i data-eusoft-scrollable-element="1">Phytophthora</i> sp., and <i data-eusoft-scrollable-element="1">Stemphylium</i> sp. in vitro using potato dextrose agar medium. On the 7th day of incubation, <i data-eusoft-scrollable-element="1">Phytophthora</i> sp. showed a reduction in colony area from 18.30 ± 1.68 to 8.55 ± 0.74 cm<sup data-eusoft-scrollable-element="1">2</sup> (53.6% inhibition). Similarly, <i data-eusoft-scrollable-element="1">Penicillium</i> sp. showed a reduction from 17.64 ± 1.46 to 8.90 ± 0.36 cm<sup data-eusoft-scrollable-element="1">2</sup> (49.4% inhibition), and <i data-eusoft-scrollable-element="1">Stemphylium</i> sp. showed a reduction from 17.76 ± 1.28 to 13.5 ± 0.73 cm<sup data-eusoft-scrollable-element="1">2</sup> (23.7% inhibition). The inhibitory effects were more significant on the 14th day, with the growth of <i data-eusoft-scrollable-element="1">Phytophthora</i> sp. further reduced to 4.9 ± 0.40 cm<sup data-eusoft-scrollable-element="1">2</sup> (72.8% inhibition), <i data-eusoft-scrollable-element="1">Penicillium</i> sp. to 5.54 ± 0.32 cm<sup data-eusoft-scrollable-element="1">2</sup> (68.8% inhibition), and <i data-eusoft-scrollable-element="1">Stemphylium</i> sp. to 8.71 ± 0.31 cm<sup data-eusoft-scrollable-element="1">2</sup> (50.8% inhibition). These results indicate the potential antifungal activity of <i data-eusoft-scrollable-element="1">Nostoc</i> sp. suspension, with the highest reduction observed in <i data-eusoft-scrollable-element="1">Phytophthora</i> sp., followed by <i data-eusoft-scrollable-element="1">Penicillium</i> sp. and <i data-eusoft-scrollable-element="1">Stemphylium</i> sp. Future research should focus on the chemical characterization of the antifungal metabolites produced by <i data-eusoft-scrollable-element="1">Nostoc</i> sp. BCAC 1226 and in vivo evaluations on economically important crops to evaluate their practical efficiency under field conditions. |
