  "abstract": "The aim of this study was to evaluate the protective efficacy of castor (Ricinus communis L.), neem (Azadirachta indica A. Juss.), and physic nut (Jatropha curcas L.) oils at concentrations of 0, 10, 20, 30, and 40% against the phytopathogen Lasiodiplodia laeliocattleyae (Sibilia) A. Alves. The oils were evaluated in vitro for their inhibitory effect on pathogen growth, using the synthetic fungicide iprodione as a positive control, and in vivo for their protective effect on cacao pods (CCN-51) artificially inoculated with the pathogen under controlled conditions. A completely randomized design was used in both experiments, and data were analyzed using two-way ANOVA and multivariate analysis. The oils exhibited distinct lipid profiles. Neem oil was characterized by higher concentrations of α-linolenic, γ-linolenic, linoleic, arachidic, palmitic, and stearic acids, while castor and physic nut oils showed contrasting compositions dominated by eucalyptol, elaidic acid, linolelaidic acid, oleic acid, and petroselinic acid. In vitro, highly significant differences were observed among treatments, days, and their interactions at both 25 and 28 °C (P < 0.0001). At 25 °C, vegetable oils increased mycelial inhibition by approximately 86–129% relative to their respective negative controls but remained 38–50% less effective than Iprodione. At 28 °C, the 10% concentration was the most effective oil treatment, approximately doubling the inhibition obtained with the fungicidal control and markedly exceeding the negative control and higher oil concentrations (P < 0.0001). In vivo, none of the vegetable oils consistently reduced pod rot severity relative to the negative control, whereas Iprodione reduced the affected area by approximately 77–82%, depending on temperature (P < 0.0001). Overall, the vegetable oils showed concentration- and temperature-dependent antifungal activity in vitro, particularly at 10%, but this activity did not translate into consistent disease suppression in vivo, where Iprodione remained the most effective treatment.",
