In Vitro Control of Tomato (Solanum lycopersicon L.) Fruit Rot Caused by Fungi Using Two Plant Extracts
The inhibitory properties of the ethanolic and methanolic leaf extracts of Vernonia amygdalina and Cola acuminata on the fungal pathogens isolated from infected tomato fruits were investigated. The pathogens were Fusarium moniliformes and Rhizopus stolonifer . Various concentrations of the extracts...
