The experiment was conducted in Centro Nacional de Investigaciones in Maracay, Aragua, Venezuela. The goal of this job was determining the efficacy of some fungicides in controlling sorghum honeydew (Sphacelia sorghi McRae). A completely block randomized with four replications was used. Three systemic triazol fungicides were used and two non triazoles were included. Each dose was subdivided in three applications: 1/4 applied at panicle pre-emergence, 1/2 applied at 50 % flowering time and 1/4 applied at postflowering time, in order to cover the whole flowering period. The variables were: incidence or infected panicles per plot, panicle infection and the total infection/ plot. According to the results there was an overall good fungicide control. There was a group constituted by Tilt and Propizole, which gave the best fungus control with 96.96 and 96.55% of effectivity in controlling of panicles’ infection and a second group was integrated by Anvil, Benlate and Plantvax which made adequate control with no significant differences among them. In conclusion, the best fungicides were Tilt and Propizole. Benlate and Plantvax gave an adequate control but they are recommended under low inoculum pressure in order to avoid resistence and for economic reasons. Anvil showed 90.43% control; however, this fungicide has low relative efficacy when it is compared with other triazol fungicides.

Objetivou-se neste estudo quantificar a evapotranspiração real (ETr) e máxima da cultura (ETc) e os coeficientes da cultura (Kc) do consórcio palma-sorgo. O experimento foi conduzido no município de Serra Talhada, PE. O delineamento usado foi em blocos ao acaso, envolvendo cinco lâminas de irrigação (0, 25, 50, 75 e 100% da evapotranspiração de referência - ETo), sob sistema de cultivo consorciado palma-sorgo. O clone de palma forrageira utilizado foi a Orelha de Elefante Mexicana (Opuntia stricta (Haw.) Haw.) e o cultivar de sorgo, Sorghum bicolor (L.) Moench, a SF 15. O sorgo foi conduzido durante dois ciclos (planta e rebrota) compreendidos em um ciclo anual da palma. A quantificação da ETr e da ETc foi realizada através do resíduo do balanço de água no solo (BAS) a cada 14 dias, com a mensuração dos componentes hidrodinâmicos. As determinações da ETc e do Kc foram realizadas com base na lâmina de 75% da ETo. Os componentes do BAS foram submetidos à análise de regressão, sendo testados modelos polinomiais. Com exceção da variação do armazenamento de água no solo, os demais componentes hidrodinâmicos do solo cultivado sob sistema consorciado palma-sorgo respondem linearmente ao aumento de lâminas de irrigação. A evapotranspiração média diária do consórcio palma-sorgo é igual a 3,0 mm dia-1, independentemente da lâmina de irrigação. Os coeficientes do consórcio palma-sorgo são iguais a 0,40, 0,68, 0,90 e 0,52 durante as fases I, II, III e IV de emissão de cladódios.

Le changement des habitudes alimentaires au cours de ces dernières années a abouti à l’apparition des maladies dites de civilisation, parmi elles le diabète sucré. Des approches diétothérapeutiques privilégient la consommation des produits céréaliers sous la forme la plus complète possible. Ce travail a pour but de tester l’efficacité des régimes expérimentaux préparés à base des grains complets des deux céréales, le sorgho (Sorghum bicolor L.) et le seigle (Secale cereale L.), sur la correction de l’hyperglycémie et des marqueurs du stress oxydant associés au diabète chez le rat mâle Wistar. Les résultats montrent que les rats diabétiques, soumis au régime seigle pendant quatre semaines, présentent une diminution significative de la glycémie qui atteint les 53,95 % à la fin de l’expérimentation, ce qui fait que leur taux en glycémie se rapproche de celui des normoglycémiques. Le sorgho blanc présente, d’une part, une diminution significative de la peroxydation lipidique intracellulaire et, d’autre part, une augmentation de l’activité de la glutathion peroxydase, la glutathion réductase ainsi que la vitamine C. Ces approches méthodologiques peuvent, en améliorant la connaissance de l’importance des céréales (fibres alimentaires solubles et des polyphénols) dans l’évolution du diabète, aboutir à des recommandations et à une éducation nutritionnelle du diabétique.
