| Abstract: The objective of this work was to evaluate the commercial formulations of Bacillus subtilis QST-713 and Bacillus pumilus QST-2808 on mycelial growth inhibition of Thielaviopsis paradoxa, for the control of the pineapple disease and growth promotion in sugarcane. The inhibition of mycelial growth was evaluated in paired culture tests. Bacillus isolates were transferred to Petri dishes 48 hours before the pathogen, and the zone of inhibition was determined. The direct effect of the autoclaved commercial formulations at 0, 0.001, 0.01, 0.1, 1.0, and 10.0% on the inhibition of pathogen mycelial growth was evaluated. Bacillus spp. potential in controlling the disease and promoting plant growth was evaluated in assays on plant development and disease... |

| ABSTRACTStem bleeding disease (resinosis) of coconut palm is caused by Thielaviopsis paradoxa and is very important in the state of Sergipe, Brazil. Understanding the epidemiological behavior of the disease is essential for establishing more efficient control strategies. Thus, we characterized the temporal progression and spatial distribution of stem bleeding in a commercial orchard under conditions of natural infection in the area of Neopolis, Sergipe. Three plots with 729 plants each were selected and evaluated every two months for stem bleeding incidence. In the temporal analysis, the monomolecular model gave the best fit to data on disease incidence, as it accurately showed the temporal dynamics of the disease during the experiment period. The spatial... |

| No plantio mecanizado da cana-de-açúcar, há dificuldades em se proteger a cultura contra pragas e doenças do solo, requerendo uma tecnologia de aplicação de produtos fitossanitários que respeite o ambiente e os custos de produção. O objetivo deste trabalho foi avaliar um sistema de pulverização para controle de doenças e pragas do solo, conjugado ao equipamento de plantio mecanizado de toletes de cana-de-açúcar, tomando como alvo-indicador a podridão-abacaxi. Delineou-se o experimento em blocos ao acaso, em área de plantio comercial da variedade SP-891115. A pulverização deu-se na região da calha do equipamento de plantio, por onde os toletes deslizam até o solo. Avaliaram-se o número de perfilhos brotados e a produção da cultura. Os resultados foram... |
