The use of plant extracts is gaining importance in plant disease management as injudicious application of chemical fungicides has led to environmental concerns. There is dire need to explore potential alternatives to minimize the harmful effects of chemical pesticides. Therefore, the present work was designed to investigate the effect of different botanicals viz. ginger (Zingiber officinale), neem (Azadirachta indica), calotropis (Calotropis gigantean), garlic (Allium sativum), and datura (Datura stramonium) against Helminthosporium oryzae, the pathogen of brown spot of rice under lab conditions. Four concentrations (2, 5, 10, and 20 mL L^-1) of each extract were used in three replications along with an untreated control. A 5 mm piece of actively growing fungal culture was placed aseptically on the treated and untreated potato dextrose agar (PDA) medium. These Petri plates were incubated at 27 ºC for 15 days. The results revealed significant inhibition of fungal growth due to different extracts over control. Ginger extracts showed 94.11% reduction in mycelial growth followed by 82.13% inhibition produced by the neem extracts. Similarly, the extracts of calotropis, garlic, and datura were found effective over control with 78.86%, 76.25%, and 63.61% inhibition, respectively. These results suggest the antifungal potential of these extracts against H. oryzae. Their use can assist the ecofriendly management of brown spot disease of rice.
