O objetivo deste trabalho foi avaliar a eficácia da termoterapia no controle de fungos associados a sementes de cumaru (Amburana cearensis A.C. Smith) de duas localidades, após tratamento térmico e químico. A avaliação da sanidade foi realizada pelo método de incubação em papel filtro (Blotter Test) e a qualidade fisiológica das sementes pelos testes de germinação e condutividade elétrica. O tratamento térmico utilizado foi por imersão em água aquecida a 60°C por 0, 5, 10 e 20 min. e o tratamento químico foi feito com o fungicida Captan. Utilizaram-se 100 sementes por tratamento (dez sementes por placa de Petri), as quais foram incubadas, por sete dias, à temperatura de 22 ± 2°C e fotoperíodo de 12h. A avaliação qualitativa e... |

The objective of this research was to determine the deterioration rate of BRS 208 and CD 104 wheat cultivar seeds, treated with fungicides, by applying the viability equation. Seeds were stored in conventional warehouses in Mauá da Serra and Londrina, in the State of Paraná, Brazil. Four seed lots were divided into four replications, half being treated with Carboxin + Thiran and the other half taken as controls, without treatment, and these were stored for 300 days. The germination data were transformed into probit, and a straight line was adjusted between 0 and 30 days. The treated seed lot of cv. BRS 208 stored in Londrina gave seed deterioration rates varying from 0.8.10-3 to 1.3.10-3, not differing from the values given for the similar lot stored in... |

ABSTRACT Seed treatment is an interesting alternative to deliver micronutrients to field crops. The aim of this study was to investigate the uptake of Cu and Zn by maize seedlings, with the application of the water-insoluble sources copper carbonate and zinc oxide as seed treatment. Treatments were composed of a control (untreated seeds), five doses of copper (0.14, 0.28, 0.56, 1.12 and 2.24 mg Cu∙seed–1) and zinc (0.55, 1.10, 2.20, 4.40 and 8.80 mg Zn∙seed–1) as well as five doses of copper and zinc combined (0.14, 0.28, 0.56, 1.12 and 2.24 mg Cu∙seed–1; 0.55, 1.10, 2.20, 4.40 and 8.80 mg Zn∙seed–1). Plants were cultivated in sand, under greenhouse conditions and, at the two-leaf stage (15 days), the root and shoot tissues dry mass and concentration of Cu... |

Seed treatment is a low-cost and efficacious method to deliver a diversity of compounds to field crops. This study evaluated the uptake of seed-applied Cu by maize and the effect on seed vigor. The treatments were composed of a control (untreated seeds) and five dosages of Cu: 0.11, 0.22, 0.44, 0.88 and 1.76 mg Cu seed–1, applied as cuprous oxide and copper oxychloride formulations. Seedling emergence and the speed of seedling emergence were determined in three periods: 1, 60 and 120 days after Cu application. Evaluations of root and shoot dry mass, Cu tissue concentration and efficiencies of Cu uptake and incorporation were conducted with two-leaf stage maize plants. Seed-applied Cu reduces the speed of maize seedling emergence, while the final emergence... |

Nitrogen (N) is the most limiting nutrient for corn production. Thereby, the goal of the paper was to evaluate inoculation methods of Azospirillum brasilense in order to partially supply N required by the crop. The experiment was carried out in Guarapuava, PR, Brasil, in 2011/2012 growing season. Randomized blocks with factorial 3 inoculation methods (seed treatment, planting furrow and non-inoculated control) x 5 doses of nitrogen (0, 75, 150, 225 and 300kg ha-1) x 8 replications was used as the experimental design. Leaf are index, foliar nitrogen content, total chlorophyll, grains per ear and yield were evaluated. There was significant interaction between inoculation methods and nitrogen fertilization to leaf area index, but not for yield. Inoculation... |

Una de las enfermedades más importantes en México y en todos los países donde se cultiva maíz, es la pudrición de la mazorca. Además de reducir el rendimiento del cultivo, esta enfermedad afecta las cualidades físicas, fisiológicas y fitosanitarias de las semillas. Los agentes causales reportados responsables de la pudrición de la mazorca, corresponden al género Fusarium (hongos transmitidos por semilla). Una forma fácil y accesible de manejar a estos patógenos es con el uso de fungicidas aplicados como tratamiento a la semilla. Sin embargo en México no existe información disponible sobre la eficacia de estos fungicidas contra las especies de Fusarium. Los objetivos en este estudio fueron: a) determinar la biodiversidad de las especies de Fusarium... |
