Biological activities of some medicinal plants against Setophaeria rostrata causing seedling blight disease in sugarcane

The antifungal properties of the leaf extracts of Pandanus odoratissimum, Cedrus deodara, Capparis Zeylanica, Mirabilis jalapa, Eicchornia crassipes, Gaedenia jasminoides, Spermacoce hispida,Nymphaea nouchali, Melothria heterophylla, Enicostemma littorale, against Setosphaeria rostrata isolated from sugarcane fields. The pathogen Setosphaeria rostrata commonly causting the seedling blight disease in sugar cane. The antifungal assay was determined by well diffusion method. Three different solvents such as methanol, ethanol and aqueous were used. Among the three solvents methanolic extracts of all the treated plant leaves showed maximum significant inhibitory activity followed by ethanolic extract. There was no activity found with aqueous extract of all the plants tested.
