| ABSTRACT: The incorporation of organic matter to the soil not only improves nutrient content, but also reduces the survival of Stenocarpella, the causal agent of stalk rot, Diplodia ear rot, and grey leaf spot, in maize stubble. We evaluated the effect of organic waste incorporation on Stenocarpella survival in maize stalks, the activity of suppressiveness-related enzymes, and nutrient contents. We conducted the assays in the municipalities of Lavras and Sete Lagoas, Minas Gerais State, Brazil. Maize stalks infested with Stenocarpella were kept in field conditions for three months after poultry litter, swine manure, fish hydrolysate, compost sewage sludge, and urea application. Infested stalks, without residue amendment, were kept on surface or... |

| Para o controle integrado de doenças, o tratamento químico das sementes de milho (Zea mays) torna-se indispensável, sendo a sua eficácia e influenciada por vários fatores, entre eles o tamanho das sementes. O objetivo do trabalho foi avaliar a relação do tamanho da semente e doses do fungicida thiabendazole no controle de Stenocarpella maydis, considerando-se diferentes tamanhos de sementes e doses do fungicida. As sementes classificadas nas peneiras 19, 22 e 24 foram inoculadas com S. maydis e tratadas com o fungicida thiabendazole em três doses, sendo avaliadas a incidência do patógeno e desempenho das sementes por meio de testes de qualidade fisiológica. Constatou-se com o tratamento fungicida, aumento na germinação, maior peso de plântulas e redução de... |

| Stem and ear rot caused by Stenocarpella maydis are responsible for severe losses in maize production. Treatment of seeds with fungicides may induce environmental damage. Hence, this study aimed to evaluate the effects of essential oils extracted from Cymbopogon winterianus, Thymus vulgaris, Cymbopogon citratus, Corymbia citriodora, Cinnamomum zeylanicum, and Syzygium aromaticum on the development of in vitro S. maydis. In addition, maize seeds were treated with these essential oils to determine their possible mode of action and effects. The oils from S. aromaticum, C. zeylanicum, and T. vulgaris inhibited fungal development at concentrations higher than 0.025%. The oils from S. aromaticum and C. zeylanicum showed seed germination rates of 89.0% and 84.5%,... |
