Control of Green Rot Fungus of Arachis hypogaea L. in Orage Using Plant Extracts

The antifungal activity of the ethanolic and aqueous fruit extracts of Zingiber officinale , Tetrapleura tetraptera , Garcinia kola and Cola nitida on the green rot fungus ( Penicillium sp .) isolated from infected groundnut ( Arachis hypogaea ) seeds in storage were investigated in vitro . Various concentrations of the aqueous and ethanolic fruit extract ranging from 5g/100ml, 10g/100ml, and 15g/100ml were separately added to Potato Dextrose Agar (PDA) media. The fungus was inoculated into the media and incubated for seven days. Results of the in vitro studies showed that the ethanolic extracts had a significant inhibitory effect (p
