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

In the present study preparation of different bioformulations ofLawsonia inermisLinn. (Henna) leaves and itsin vitroantifungal activity were evaluated againstCurvularia 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, againstC. lunata. On the basis of results obtained, best bioformulation will be used for eco-friendlyin vivocontrol of disease.

Automated summary

In this study, different bioformulations of Henna leaves were prepared and evaluated for their in vitro antifungal activity against Curvularia lunata, the causative agent of leaf spot disease in maize. The results showed that four formulations exhibited the highest antifungal activity. The best bioformulation will be used for environmentally friendly in vivo disease control based on these findings.
