Effect of Some Plant Leaf Extracts on The Growth and Sporulation of Two Pathogenic Fungi

In the present investigation an attempt has been made to study the effect of ten plant extracts on the growth and sporulation of two pathogenic fungi i.e., Fusarium semitectum Berk and Rav. and Phoma nebulosa (Pers. ex. S.F. Gray) Berk. The plant leaf extracts of Acalypha indica L., Canna indica L., Cannabis sativa L., Nerium odorum Sol., Papaver somniferum L., Tridax procumbens L., Thevetia nerefolia J. and Vinca rosea L. have shown stimulatory effect (an increase in dry weight was observed). Nerium odorum Sol. has shown only slight stimulatory effect on the two pathogenic fungi. Cannabis sativa L. has shown only slight inhibitory effect on F. semitectum Fusarium semitectum only. However, Datura metal L. followed by Ocimum sanctum L. has shown inhibitory effect on the growth and sporulation of the two pathogenic fungi. This clearly shows the possible presence of an active principle of antifungal activity in Datura metal and Ocimum sanctum.
