Abstract:
This study was carried out with the objective of evaluating the antifungal potential of aqueous and ethanol extracts of eight different plant species in vitro and in vivo against Colletotrichum kahawae in completely randomized design with three replications. The extracts were from Hagenia abyssinica, Allium sativum, Phytolacca dodcandera, Croton macrostachyus, Maesa lanceolata, Eucalyptus globules, Eucalyptus citriodera and Lippia adoensis. Subsequently, two most effective plant extracts were tested in vivo against the disease on detached green coffee berries and seedling applying the extracts at 3 different times of application (at the time of inoculation and 48 h before and after inoculation) on the pathogen. The study indicated that the inhibitory effect of the extracts depended on the type of plant species used, method of extraction and time of application of the extracts. Generally, A. sativum and C. macrostachyus aqueous and ethanol extracts were the most effective plants that significantly reduced radial growth of the pathogen compared to the control. A. sativum reduced radial growth of the pathogen in ethanol and aqueous extracts by 83 and 100%, respectively and C. macrostchyus by 68 and 88%, respectively. Furthermore, A. sativum extracts consistently reduced disease severity on detached green berries and seedling in greenhouse at all times of application. Nevertheless, the efficacy of C. macrostachyus on detached green berries and seedlings was inconsistent and variable based on method of extraction and time of application of the extracts. The study indicated the possible use of extracts of A. sativum as an alternative means of CBD (coffee berry disease) management but further study at field conditions should be carried out to verify the result.
