| El cultivo de crisantemo 'Harman' en la región de Texcoco se ve afectado por diversas plagas y enfermedades que demeritan su producción. En la zona, el uso indiscriminado de agroquímicos sintéticos ha ocasionando la aparición de plagas y enfermedades resistentes, fractura del control biológico natural y generado problemas ambientales y de salud humana. Con el objetivo de proporcionar alternativas para el control de plagas y enfermedades, que además contribuyan a la calidad de flor de corte, se evaluaron los tratamientos: miel de abeja al 2 % (M), nitrógeno + ácidos húmicos (N+AH), S. cerevisiae (SC) y testigo regional (T), bajo un diseño experimental de bloques completos al azar con tres repeticiones. Además, en los tratamientos M, N+AH y SC se... |

| The monitoring network IFREMER /REMORA is assessing on a yearly basis, from February to December, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year class ; and "adults" = two-years class), deployed among various stations of the main French oyster areas. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be considered as an accurate estimation of professional oyster ongrowings. Based on REMORA results, generally tallied with professional observations, 1998 on the whole was a second year of low mortality. However several areas remained affected by significant mortalities : the baie des Veys (in Normandy), Morlaix and Pen-Bé (in Brittany) and Marennes (in... |

| The network IFREMER/ REMORA watches every year, from February to December, mortality, growth and quality criteria of two oyster batches ("juveniles" = one-year class ; and "adults" = two-years class), distributed among various stations of the main French oyster areas. This network is a tool for trend estimations (geographic and chronological, on the national scale) ; it must not be regarded as an accurate estimation of professional oyster ongrowings. With regard to REMORA results, generally tallied with professional observations, 1998 on the whole was a second year of low mortality. But some areas remained affected by significant mortalities such as Pen-Bé in South Brittany. The year 1998 was overall a very poor year for growth : the mean oyster weight in... |

This network is a tool for trend estimations (geographic and chronological, on the national scale). With regard to the Breton stations of the network, the year 1999 showed a small increase of mortality rates, both in adults alter their transfer on the REMORA stations and in juveniles during the Summer season. this was particularly observed in Morlaix, Aber Benoît and Pen-Bé. Although it was better than 1998, the year 1999 was a poor year for growth, especially in North Brittany (62.5 g in... |
