Assessment of fungitoxic effects of botanicals on the management of growth in Colletotrichum lindemuthianum, the incitant of cowpea anthracnose

Abstract

Antifungal activities of thirty six botanicals were assessed with an objective to find out the potential of botanicals against the mycelia growth of Colletotrichum lindemuthianum in vitro. Plant specimens were collected locally based on its medicinal, antimicrobial properties and extracted using aqueous means. The botanicals were tried in six different concentrations. Strychnos, Rauwolfia, Pongamia, Azadirachta, Datura, Zingiber, Allium cepa, Allium sativum, Eucalyptus, Aegel and Momordica plant extracts at 25% and 30% concentration arrested the growth of the mycelia to the tune of 100% which can be recommended for the use in field.
