Comparative analysis of bioformulations against Curvularia lunata (Wakker) Boedijn causing leaf spot disease of maize

Abstract

In the present study preparation of different bioformulations of Lawsonia inermis Linn. (Henna) leaves and its in vitro antifungal activity were evaluated against Curvularia lunata (Wakker) Boedijn caused leaf spot disease in maize. Thirty herbal formulations were prepared using plant extracts, elicitor and binder, and assayed for antifungal activity by poison food technique. Among all the bioformulations, optimum activity was observed in formulation number 4, 12, 19 and 28 i.e. 77.82%, 79.84%, 83.47% and 81.45%, respectively, against C. lunata. On the basis of results obtained, best bioformulation will be used for eco-friendly in vivo control of disease.
