Chilli (Capsicum annuum L.) or red pepper, a member of solanaceae family is mainly cultivated as annual herbaceous vegetable and commercial spice crop. Anthracnose caused by Colletotrichum capsici is a serious disease in chilli growing areas and occur as a pre-harvest and post harvest fruit rot, causing extensive losses in chilli. In this study, citronella essential oil was tested in vitro at different concentrations viz., 0.25%, 0.5%, 0.75%, 1%, 1.25% and carbendazim 0.01% against radial growth of Colletotrichum capsici. The minimum radial growth and maximum percent inhibition was recorded at a concentration of citronella @ 1.25 % (2.50 mm and 97.22%) followed by citronella @ 1% (5.95 mm and 93.38%) as compared to treated carbendazim- (98.41%) and untreated check (00.00%). During Rabi 2019-2020 the effect of microalgae and citronella essential oil were tested against the disease severity, growth & yield parameters under field conditions in prayagraj, Uttar Pradesh. Among the treatments minimum disease severity (%) was recorded in T3–citronella oil @ 1% + microalgae@ 4kg/acre (24.92%)as compared to treated T7- carbendazim (21.68%) and untreated control T0 - Control (35.92%). The maximum plant height (cm), number of branches, fruit length and yield was recorded maximum in T3 – citronella oil @ 1%+microalgae @ 4kg/acre (60.18 cm, 28.00, 9.60 cm and 4.40 t/h) when compared to control. The minimum per cent fruits infected (%) was recorded in T3 – citronella oil @ 1%+microalgae @ 4kg/acre (23.08) followed by, T2 – citronella oil @ 1% + microalgae@ 3kg/acre (24.08), as compared to treated T7- Carbendazim (21.02) and untreated control T0 - control (34.60). Results showed that microalgae and citronella essential oil can be used as ecofriendly compounds for the management of anthracnose disease in chili.
