O presente trabalho teve como objetivo avaliar o controle de doenças do mamoeiro, utilizando extratos vegetais (alho, angico e manjericão), óleos naturais (urucum e algodão), indutores de resistência (Bion®, Ecolife® e Agro-mos®) e fungicida Mancozeb/Dithane. O Experimento I consistiu-se da avaliação dos tratamentos sobre o crescimento micelial de Colletotrichum gloeosporioides, in vitro; no Experimento II, efetuou-se a inoculação artificial do fungo sobre frutos sadios de mamão e avaliou-se a severidade da podridão peduncular, por meio de escala de notas e, no Experimento III, aplicaram-se os tratamentos em mudas de mamoeiro, inoculadas artificialmente com C. gloeosporioides, avaliando-se a antracnose com escala de notas. Os resultados obtidos demonstraram que extratos de angico e alho proporcionaram um menor crescimento micelial, in vitro, e o Bion® manteve um eficiente controle da podridão peduncular em frutos. Nas mudas, o efeito do alho, angico e Bion® diferiram significativamente dos demais, sendo que o Bion® apresentou melhor controle da severidade da antracnose. Assim, o controle da podridão peduncular e antracnose em mamoeiro, com produtos naturais e indutores de resistência, pode ser uma opção viável na substituição de agroquímicos.This present work had as objective to evaluate the control of papaya diseases using natural extracts (Allium sativum L., Anadenanthera peregrina L. Speng, and Ocimum basilicum L.), natural oils (Gossypium hirsutum L. and Bixa orellana L.), resistance inducers (Bion®, Ecolife® and Agro-mos®), and a chemical fungicide (Mancozeb/Dithane). Experiment I was conducted to evaluate the inhibitory potential of the treatments on Colletotrichum gloeosporioides mycelial growth in vitro; in Experiment II, artificial inoculation of fungus was performed on healthy papaya fruits, and the severity of stem-end rot was evaluated using a disease index; and in Experiment III, treatments were applied on papaya seedlings artificially inoculated with C. gloeosporioides, and anthracnose was evaluated by means of a disease index. Obtained results showed that extracts of Anadenanthera and Allium were responsible for lower mycelial growth in vitro, and Bion® was efficient for papaya stem-end rot. In papaya seedlings, the effects of garlic, angico and Bion® differed significantly from the rest, with Bion® showing the best results for anthracnose control. Papaya seeds were not affected by C. gloeosporioides. Thus, alternative control to stem-end rot and anthracnose on papaya with natural products and resistance inducers should be an option viable for agrochemicals substitutio
