Efficacy of citronella essential oil for the management of chilli anthracnose
Abstract
© 2018, Koninklijke Nederlandse Planteziektenkundige Vereniging. The potential of citronella essential oil for the management of chilli anthracnose caused by Colletotrichum acutatum was investigated. In in vitro tests, citronella essential oil inhibited mycelial growth at 0.25, 1.25 and 2.5 μL citronella/mL water, reduced conidial germination, and inhibited germ tube elongation at 1.25 μL/mL. Citronella essential oil applied as a protective or curative treatment to chilli cv. Django fruits reduced anthracnose infection. Efficacy of citronella essential oil was substantially effective to chemical fungicides and relatively superior to a biofungicide in both protective and curative tests. However, citronella essential oil at 2.5 μL/mL was phytotoxic to chilli fruits. Therefore, the most effective rate of citronella essential oil was at 1.5 μL/mL with inhibition of pathogen growth, reduction of anthracnose symptoms, and no observable phytotoxic response on chilli fruits. Citronella essential oil may be a viable alternative to chemical fungicides for the management of chilli anthracnose.
