No. of bitstreams: 1 Carmelita dos Santos Oliveira.pdf: 494764 bytes, checksum: 6ad60afb4a43f99c279f2ebbed666902 (MD5) Previous issue date: 2012-06-19 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / A fusariose é um dos principais problemas fitossanitários na cultura da pimenta-do-reino, por causar a morte das plantas e, consequentemente, redução da produtivida-de, acarretando prejuízos econômicos à pipericultura. Considerando as dificuldades e limitações no controle desta doença, o controle biológico com o fungo Trichoderma spp. surge como alternativa a ser incorporada em seu manejo integrado. Objetivou-se neste trabalho avaliar a eficiência do produto Trichodermil® no controle da fusari-ose em lavouras de pimenta-do-reino localizadas na região Norte do Espírito Santo, no município de São Mateus. O uso do Trichodermil® reduziu a intensidade de doen-ça nas lavouras, proporcionando eficiência de controle de até 50%. A mistura de compostos fornecedores de matéria orgânica, com exceção da Polycana®, reduziu a eficiência do Trichodermil®. O intervalo entre aplicações de 90 e 120 dias foram os que apresentaram melhor controle, nas doses de 1 ou 2 mL por planta / The fusarium wil is a major disease of black pepper. Frequenttly it causes plant and, consequently, reduces yield, resulting in economic losses for black pepper produc-ers. Considering the difficulties and limitations in controlling this disease, biological with Trichoderma spp. could be an alternative strategy to be inculded in the integrat-ed disease management. The objective of this research was to evaluate the efficien-cy of Trichodermil® in controlling fusarium disease n crops of black pepper in the North of the Espírito Santo State in the city of São Mateus. The use of Trichodermil® reduced the disease in the field up to 50%. The mixture of organic matter suppliers compounds, with the exception of Polycana®, reduced the efficiency of Trichodermil®. The application intervals of 90 and 120 days were those with better control, at doses of 1 or 2 mL per plant
