Manejo in vitro de antracnosis (Colletotrichum acutatum Simmonds) en aguacate mediante el uso de principios activos botánicos

Anthracnose is the disease caused by the phytopathogenic fungus of the genus Colletotrichum, that decreases quality and yield. The objective of this work was evaluated botanical active principles (PABs) for its control. The pathogen was isolated, the identification was made morphologically, the pathogen identity confirmation was carried out bymeans of molecular technique (ITS-PCR). Later, in vitro tests were carried out with D-limonene, eucalyptol and β citronellol. Data was analyzed byprobit analysis, ANOVA and Tukey test (p ≤ 0.05). The mycelial growth, percentage of sporulation and germination of conidia were measured. TheColletotrichum acutatum was identified. In the in vitro evaluation, β citronellol showed the greatest  effectiveness in the different variables, with inhibition intervals of 29 to 89% in mycelial growth, from 61 to 100% in sporulation, and germination from 96 to 100%. Thus, β citronellol represents a botanical alternative in vitro for anthracnose control.
