Antifungal activity of camphor against four phytopathogens of Fusarium

Fusarium, one of the main fungal pathogens, can infect field crops, horticultural plants and cause great economic loss. The exploitation effective environmentally friendly Fusarium control agents has important application value for agricultural production. In this study, an investigation was completed on antifungal activity camphor against four common phytopathogens: oxysporum G5, F. solani G9, verticillioide, graminearum. method adopted mycelial growth inhibition. minimum inhibitory concentrations (MIC) tested fungi were 4.0, 2.0 mg/mL, half maximal (IC 50 ) 2.0, 1.0 respectively. paper proper also involves fungicidal mechanisms via cell membrane permeability, proteins nucleic acids leakage using colorimetry scanning electron microscopy. results indicated that could exhibit pronounced activities fungi, cytomembrane may be target camphor. preliminary mechanism revealed destruction, enhancing permeability releasing intracellular macromolecules, such as proteins. conclusion, our suggested a promising alternative phytopathogenic in production industrial crops. • Camphor significantly inhibit . disrupt integrity cytomembrane. at several different levels. used to
