| Summary: | colletotrichum gloeosporioides, is a disease of great importance in soursop cultivation since it can cause large production losses by being present in all phenological stages of the crop, as an alternative to the use of chemical synthesis products for its control, it was investigated the in vitro effect of eight extracts in hydrolate form obtained from Bougainvillea spp., Hibiscus sabdariffa L., Mangifera indica L., Carica papaya L., Pimenta dioica L. and Psidium guajava L., using the poisoned media technique . In the first stage, the hydrolates were evaluated at 50% concentration V/V, those that achieved total inhibition of the pathogen were evaluated again to calculate their minimum inhibitory concentration (MIC), the daily growth of the radial diameter of the pathogen as well as the number of total and germinated conidia. The results show that all the evaluated plants have compounds with fungistatic capacity on C. gloeosporioides when tested in vitro; in the first stage P. dioica L., D. ambrosioides L., M. indica L. and Bougainvillea spp. inhibited the total development of the pathogen, while H. sabdariffa L. and P. guajava L. showed a minor inhibition in mycelial growth; however, they showed high antisporulant capacity (99.45% and 83.33% respectively); on the other hand, C. papaya showed low inhibition in both sporulation and mycelial growth. In the second stage, only P. dioica L. inhibited the total development of C. gloeosporioides, for which it achieved the lowest MIC with 40%, the other treatments failed to inhibit mycelial growth but all showed antisporulant capacity according to the comparison test Stocking by Tukey. The P. dioica L. hydrolate showed the lowest minimum inhibitory concentration with 40% (V/V), while for the hydrolates the D. ambrosioides L., Bougainvillea spp. (leaf, flower and bract) and M. indica L. the minimum inhibitory concentration was 50% (V/V) on C. gloeosporioides. |
