Abstract:

Tomato (Solanum lycopersicum L.) is one of the commercially important major vegetable crops grown throughout the tropics and subtropics. Septoria leaf spot caused by Septoria lycopersici Speg. is one of the most destructive diseases of tomato and is particularly severe in areas where wet, humid weather persists for extended periods. The bio assay of botanicals and Indigenous technical knowledge (ITKs) forms the prerequisite for the field evaluation. In the present investigation eight botanicals and eight ITKs were evaluated at 5, 10 and 15 per cent concentration against S. lycopersici under laboratory condition. Among the eight botanicals, Allium sativum (Garlic) bulb extract found to be significantly superior over other treatments in inhibiting the mycelial growth (65.10 %) of S. lycopersici followed by Duranta goldiana (Duranta) leaf extract (53.73 %) and lowest inhibition was observed in Tagates erecta (Marigold) leaf extract (23.53 %) at 15 per cent concentration. In vitro spore germination bioassay of ITKs revealed that, highest inhibition (76.67 %) of conidial germination over control was shown by Cow urine which was on par with Panchagavya (73.33 %) and the least inhibition was observed in biodigestor (33.33 %) at 15 per cent concentration.
