The aim of this study was to control phytopathogens associated with mango decay by exposing them to antifungal thyme oil-starch/agave fructans microcapsules in Nylon sachets. Results showed that different doses of the microcapsules effectively inhibited the growth of pathogens and reduced the incidence and severity of Colletotrichum gloeosporioides in mango.
The aim of the present work was to control phytopathogens associated to mango decay by exposure to antifungal thyme oil-starch/agave fructans microcapsules in Nylon sachets. Fusarium pseudocircinatum, Alternaria alternata, Neofusicocum kwambonambiense, Cladosporium pseudocladosporioides, and Colletotrichum gloeosporioides were isolated from mango fruits and its mycelial growth was 100% inhibited with 5 mu L of thyme oil. Thyme oil was microencapsulated with modified starch/agave fructans by spray drying. Thymol content, size, and shape of microcapsules were evaluated. Antifungal sachets were prepared by filling Nylon bags (4 x 4 cm) with different doses of thyme oil microcapsules: 0.10, 0.15 and 0.20 g. The mycelial growth of all microorganisms was controlled with 0.10, 0.15 and 0.20 g of antifungal sachets. The incidence (75 and 65%) and severity (77 and 41%) of C. gloeosporioides were effectively reduced in mango, respectively, using 0.10 and 0.20 g of antifungal sachets.
