Study on Antibacterial Activity of Extracts from Pinus elliottii against Plant Pathogenic Fungi

The research aimed to study the inhibition of Pinus elliottii against plant pathogenic fungi and by using the mycelium growth rates,the inhibition was measured.The results showed that Pinus elliottii had inhibitory components to plant pathogens.The 60% ethanol extracts had notable inhibiting effects on the different fungi tested at 20 mg/ mL.The inhibitory rates of the 60% ethanol extracts on Fusarium graminearum,Alternaria alternate,Alternaria solani,Fusarium oxysporum f.sp.mornordicae were all above 40%.Besides,over 1 hour extraction time and over 70 ℃ extraction temperature will get better antibacteriat effect.
