Natural Fumigant Efficacy of Giloy Leaf Essential Oil for Control of Fungal Infections and Enhancement of Shelf Life of Pigeon Pea Seeds

Narendra Kumar

Abstract:
Background and Objective: Pigeon pea [Cajanus cajan (L.) Millsp.] suffers great losses due to fungal infections. For protection farmers use sulphos which have negative effects. So essential oils from higher plants need to be tried for its antifungal potential and safe storage of pigeon pea having no negative effects. Materials and Methods: The fungal investigations on stored food seeds of Pigeon pea were done through agar plate as well as blotter paper methods. Essential oils were separately isolated from 20 plants. MIC, nature, spectrum, effect of physical factors were decided and in vivo efficacy of Tinospora cordifolia (T. cordifolia) leaf oil was studied for safe storage of pigeon pea. Results: The fungal investigations on stored food seeds of stored food seeds of Pigeon pea [Cajanus cajan (L.) Millsp.] showed presence of 16 fungal species. Out of these fungal species Aspergillus flavus, A. niger was found to be dominant on the basis of frequency (%). The Tinospora leaf oil showed absolute toxicity (100%) against frequently present Aspergillus flavus, Aspergillus niger at concentration of 400 ppm and fungicidal at 600 ppm. At 500 ppm inhibited 10 fungi and at 800 ppm concentration 15 fungi. There was no adverse effect of physical variants viz., temperature treatment up to 100°C, autoclaving at 15 lb/square inch pressure at 120°C and storage up to 120 days on potential of leaf oil. In vivo experiments revealed that Tinospora oil when applied as seed dressing agent and as a fumigant was able to preserve food seeds of pigeon pea up to 120 days having minimal changes in organoleptic behaviour during storage. Conclusion: It revealed that T. cordifolia leaf essential oil have more fungitoxic efficacy in comparison to synthetic pesticides.
