The effect of essential oils on the hyphal growth of the causative agent of rhizopus rot of strawberry fruit Rhizopus stolonifera

vulgaris on the hyphal growth of the causative agent of rhizopus rot of strawberry fruit Rhizopus stolonifer.It was found that essential oils of A. sibirica, Citrus × sinensis, T. vulgaris, E. globulus, Citrus limon, P. sibirica and P. sylvestris significantly reduce the growth of hyphae statistically by 81.5, 79.9, 67.7, 50.5, 48.8, 48.6 and 27.5%, respectively.J. communis essential oil had no effect on hyphal growth.Despite the decrease in the average length of hyphae, certain variants with essential oils of P. sylvestris and C. limon were found to contain some individual spores, on which these oils had not an inhibitory but a stimulating effect.The same spores were found in the variant with J. communis essential oil.Along with a decrease in hyphal growth, essential oils of E. globulus, J. communis, P. sylvestris and C. limon increase the coefficient of variation in hyphal length by 20.4,47.4, 113.1 and 346.0%, respectively.In addition, essential oils of T. vulgaris, E. globulus, J. communis, P. sylvestris and C. limon increase the hyphal length oscillation coefficient by 21.3, 39.4, 57.6, 217.1 and 568.4%, respectively.Essential oils of P. sibirica and A. sibirica reduced the coefficients of variation and oscillation of hyphal length.Thus, A. sibirica, Citrus × sinensis and T. vulgaris essential oils as a natural remedy against R. stolonifer are recommended for further study.
