Abstract
Six plant extract viz., Datura (Daturastramonium), Eucalyptus (Eucalyptus globulous), Karang (Pongamiaglabra),Neem (Azadirachtaindica), Madar (Calotropis gigantean) and Wild sage (Lantana camara) were evaluated in-vitro by poison food technique @ 3, 6, 9 and 12% concentrations against Alternariabrassicaecausing blight of mustard. The results revealed that all the plant extracts inhibited the percent growth inhibition against test fungus as compared to control. However A.indica was found most efficacious with growth inhibition of (38.7%) followed by E. globulus (36.7%). Some extract such as P. glabra and D. stramonium showed moderate inhibition over control (30.9 and 21.6 respectively). Among all plant extract, C. gigantean showed least (15.3%) inhibition over control against A. brassicae. These plant extracts can possibly be used as management of seedborne pathogenic fungi in an eco-friendly way.
