- Abstract
In forestry practice, the prevention and fight against insect pests and diseases is a priority to preserve the health of these ecosystems. To combat it, insecticides of chemical and biological origin have been used. However, there are alternatives that have not yet been investigated, e.g., the use of agro-industrial waste. In the mezcal distillation process, polluting liquid residues called vinasses are generated, and these can be considered for pest control. In this project, the effect of vinasse from Agave durangensis subjected to different treatments was studied to evaluate its effect on forest phytopathogenic fungi. The mezcal vinasse was characterized physicochemically and by its metabolites. Furthermore, the percentage of inhibition in vitro of phytopathogenic (causing root wilt) fungi isolated from Pinus cooperi seedlings was studied. The fungi inhibition was related to the vinasse concentration. The lower pH and sterile raw vinasse showed a better inhibition effect. Four phytopathogenic strains of Pinus cooperi were isolated and identified, which corresponded to the genera Fusarium, Aspergillus, and Penicillium. None of the isolated were able to grow in potato dextrose-mezcal vinasse medium (PDMVM). Therefore, the mezcal vinasse showed fungicide activity in vitro against all strains.
