Abstract:
An investigation was carried out at experimental block for chilli crops, Vegetable Research Centre, Pantnagar to evaluate seven botanicals under in vitro and best of three botanicals among them were tested under in vivo conditions against anthracnose of chilli (Colletotrichum capsici).The experiment was conducted during rabi season of 2018 – 2019. Results revealed that among the seven botanicals tested for their efficacy against C. capsici under lab condition at 5 per cent concentration neem was found to be superior with maximum growth inhibition of 27.77 per cent of the test pathogen followed by Tulsi (21.87%) as compared to other botanicals whereas minimum growth inhibition of 3.70 per cent was observed in Parthenium. Among the seven botanicals, at 10 per cent concentration Neem (32.96%) with maximum growth inhibition was again found to be superior followed by Tulsi (27.26%) as compared to other botanicals whereas Parthenium (6.30%) showed minimum growth inhibition of the test pathogen. Among the seven botanicals, at 15 per cent concentration Neem (44.21%) was found to be the best followed by Tulsi (42.93%) with maximum growth inhibition whereas drumstick (9.25%) showed minimum growth inhibition. Among the 10 treatments under field condition Neem @ 15 per cent showed minimum PDI (48.88%) followed by Neem @10% (55.28%) and were found to be effective as compare to other treatments. Neem @15 per cent gave maximum yield (13.39q/ha) followed by Neem@10 per cent (13.23q/ha) as compared to other treatments and minimum yield (10.86 q/ha) was recorded in check.
