SUMMARY:

Brazil annually produces about 6.7 million tons of bananas, the cultivation of banana trees (Musa spp) in the country moved R$ 9.9 million reais in the year 2021, being established, therefore, as an activity of great social importance and economic for the country. The northeast region represents 40% of the Brazilian areas cultivated with bananas and the State of Alagoas plays an active part in this production. However, the average yield of banana production in Alagoas is two tons below the national range, data resulting from limitations generated by diseases in the post-harvest of fruits, such as anthracnose, which is caused by phytopathogens of the genus Colletotrichum, whose infection it is characterized by small lesions that coalesce and form large necrotic areas in the fruit's epidermis, reducing their commercial shelf life by stimulating the early ripening of the fruit, generating losses of up to 40% of production. Therefore, in view of the relevance of investigations regarding the Colletotrichum species associated with banana anthracnose, this study aimed to characterize the distribution, prevalence and resistance of Colletotrichum isolates in the State of Alagoas, based on physiological, morphocultural, pathogenic characteristics and molecular properties of these species. The results obtained here indicate that banana anthracnose in the state of Alagoas is associated with the species Colletotrichum siamense and Colletotrichum musae¸ and the fungicide difenoconazole inhibits up to 85% of the mycelial growth of C.musae.
