In pursuit of an environmentally benign fungicide alternative, the current study explored antifungal activity Chlorella vulgaris extracts against six plant pathogenic fungi (in vitro). The well diffusion agar method was used to investigate growth inhibition Fusarium oxysporum, sp., solani, A. flavus, niger, and alternata using three C. viz. methanol (CvME), acetone (CvAE), diethyl ether (CvDE). Different concentrations CvDE were also investigated F. oxysporum. morphological modifications in oxysporum treated with (5 mg/kg) studied SEM chemical composition determined by GC–MS analysis. All extracts, exception alternata, found be effective inhibiting fungi. extract, followed CvME CvAE, efficient tested most a 73.3% inhibition. effects various on dosage dependent. micrograph revealed that CvDE-treated had substantially less conidia than control. treatment damaged mycelial structure as well. Major components detected Heptaldehyde (15.7%), Octadecenoic acid, methyl ester (12.6%), Hexadecanoic acid (12%), 3-Decyn-2-Ol (10.98%), (E)-3,7,11,15-tetramethylhexadec-2-ene (9.76%), heptadecane-1,2,3,4,5-pentol (8.7%), Docosane, 4-methyl (7.28%).
