Abstract

Branch canker is a stem disease of tea caused by Macrophoma theicola. The antifungal activity of aqueous extract of Acrous calamus was found to fully inhibit growth of Macrophoma sp. at 10 percent concentration. While the plant extracts of Curcuma longa and Hibiscus rosasinensis showed good results. The inhibitory potential of Psidium guajava and Allamanda cathartica indicated significant effect at 15% concentrations followed by Murraya koenigii, Azadirachta indica and Artemisia nilagirica. Moderate inhibition was noticed by Carica papaya extracts followed by action of Cinnamomum burmannii and Dryopteris linearis extracts. The extracts of Tithonia diversifolia, Conyza ambigua and Adhatoda vasica level at 10% showed lowest control potential.
