Summary

Colletotrichum gloeosporioides é o agente causal da antracnose, principal doença pós-colheita do mamoeiro. O objetivo deste trabalho foi verificar a fungitoxicidade do extrato etanólico de representantes de cinco famílias de plantas e óleo essencial da família Asteraceae sobre o fungo Colletotrichum gloeosporioides coletados de frutos de mamoeiro (Carica papaya L.). Na produção dos extratos etanólico foi utilizado onze plantas, sendo duas para a obtenção do óleo essencial. Os extratos foram obtidos a partir de uma solução de etanol 80% combinado ao pó das folhas das plantas e a extração do óleo por meio do aparelho Clevenger. Os resultados referentes aos extratos foram submetidos à análise de variância e teste de Tukey a 5%. E os provenientes do óleo essencial foram avaliados por porcentagem de inibição do crescimento micelial (PICM). Tanto os extratos como óleo essencial foram capazes de inibir o crescimento C. gloeosporioides. O resultado mais promissor foi obtido com o óleo essencial de Baccharis trimera que promoveu inibição de 100% do fungo em alíquotas a partir de 15μL.

Summary translation

Colletotrichum gloeosporioides is the causal agent of anthracnose, the main postharvest diseases of papaya. The aim of this study was to investigate fungitoxicity ethanol extract of representatives of five families of plants and essential oil of the Asteraceae on Colletotrichum gloeosporioides collected from papaya fruit (Carica papaya L.). In the production of ethanol extracts was used eleven plants, two for obtaining the essential oil. The extracts were obtained from a solution of 80% ethanol combined with the powder of the leaves of the plants and oil extraction by means of Clevenger apparatus. The results for the extracts were submitted to ANOVA and Tukey test at 5%. And from the essential oil were evaluated by percentage inhibition of mycelial growth (PICME). The extracts and essential oils were able to inhibit C. gloeosporioides. The most promising result was obtained with the essential oil of Baccharis trimera that it inhibited 100% of the fungus in aliquots from 15μL.
