Resumo: | Anthracnose is a disease caused by the pathogen Colletotrichum gloeosporioides affects avocado fruits (Persea americana Miller), making them unfit for commercialization. The aim of this study was to determine the effect of essential oils on the control of anthracnose in avocado fruits and its influence on the physico-chemical quality. The work was conducted at the Phytopathology Laboratory - UFPB, campus II. The fruits of avocado were treated with essential oils of lemon grass, cinnamon, eucalyptus, ricin, copaiba, andiroba, rosemary, canola, clove and flaxseed, which were added to the BDA culture medium at a concentration of 0.75 μLmL-1 and added to these two drops of Tween 80. In addition to the fungicide Tiabendazole 400 ml / 100 L added in the BDA medium and the control (pure culture medium). The following were evaluated: index of mycelial growth rate, conidia production and pathogen severity. The physical-chemical evaluations of the fruits were: loss of fresh mass; peel strength; pH; SS / AT ratio. The essential oils of cinnamon, lemon grass, eucalyptus, cloves, fennel, copaiba and rosemary reduce mycelial growth. The oils used show potential as an alternative treatment reducing the use of fungicides. Cinnamon oil in the concentration 0.75 μLmL-1 significantly reduces the growth and sporulation of the pathogen. Essential oils do not interfere with post-harvest quality of avocado fruits P. americana Miller. |

Buscando-se o manejo alternativo de doenças, objetivou-se determinar o efeito de óleos essenciais no controle da antracnose em frutos de abacateiro e sua influência sobre a qualidade físico-química. O trabalho foi conduzido no Laboratório de Fitopatologia de Universidade Federal da Paraíba, campus II. Os frutos de abacateiro foram tratados com óleos essenciais de capim-limão, canela, eucalipto, rícino, copaíba, andiroba, alecrim, canola, cravo e linhaça, que foram adicionados ao meio de cultura BDA, na concentração de 0,75 μLmL-1 e adicionado a estes duas gotas de Tween 80. Além do fungicida Tiabendazol 400 ml/100L acrescido no meio BDA e a testemunha (meio de cultura puro). Foram avaliados: índice da velocidade de crescimento micelial, produção de conídios e severidade do patógeno. As avaliações físico-químicas dos frutos foram: perda de massa fresca; firmeza da casca; pH; relação SS/AT. Os óleos essenciais de canela, capim limão, eucalipto, cravo, erva-doce, copaíba e alecrim reduzem o crescimento micelial. Os óleos utilizados mostram potencial como tratamento alternativo reduzindo o uso de fungicidas. O óleo de canela na concentração 0,75 μLmL-1 reduz significativamente o crescimento e esporulação do patógeno.
