Resumen

The contribution of vegetables to food security and economic development in Colombia, as well as to environmental problems worldwide, justifies the interest to design sustainable production strategies for the agro-chain. This study was developed to evaluate the effect of the application of essential oils and agricultural inputs in chili peppers, beans and eggplants in Codazzi, Cesar, Colombia. The methodology included the compatibility analysis between pesticides used in these vegetables, and Lippia alba and Cymbopogon citratus oils in relation to their biocidal effect in vitro on native strains of Macrophomina phaseolina, Phytophthora capsici and Colletotrichum gloeosporioides. Applications of thiabendazole in an individual basis and combined with oils were carried out in the field. Physicochemical and microbiological indicators of soil, pests and diseases incidence and crop yield were measured. Oils controlled up to 97% of plant pathogens in vitro and exhibited compatibility with carbendazim and thiabendazole. In the field, up to 67 % of disease control was observed with C. citratus + thiabendazole compared to the control (p = 0.00), yields were close to the regional average, and better microbiological and physicochemical soil conditions were observed. In conclusion, there are differences in the edaphic effect between treatments, as the agrochemical and the oil combinations were more favorable than the individual effect of each product on the variables evaluated. The above exhorts to continue soil evaluations with oils to elucidate the duration of the described effects.
