Abstract: Con el propósito de valorar la conveniencia de aplicar fungicida para mejorar la productividad del trigo harinero y cristalino cuando incide la roya amarilla y el complejo de enfermedades foliares bajo condiciones de temporal, se establecieron en tres localidades del estado de Tlaxcala las variedades Gema C2004 y Tlaxcala F2000. Las variables analizadas fueron días a floración y a madurez, altura de planta, rendimiento de grano, incidencia de roya amarilla en el follaje y en la espiga e incidencia y severidad de enfermedades foliares. En las tres localidades la variedad de trigo harinero Tlaxcala F2000 superó en rendimiento de grano a la variedad de trigo cristalino Gema C2004 de 9% hasta 46%. Las enfermedades en su conjunto causaron mermas en el rendimiento hasta 26%. Sportak fue el fungicida que se asoció con el mejor control de las enfermedades, lo cual se reflejó en una mayor productividad de grano con incrementos promedios 26.5 y 29.4%, cuando incidió roya amarilla y enfermedades foliares, respectivamente. Los resultados indican que es conveniente la aplicación de fungicida para reducir mermas en la producción de trigo de temporal. With the aim to evaluate convenience of applying fungicide to improve productivity of flour wheat and white wheat when there is incidence of yellow rust and complex of foliar diseases under rainfall conditions, varieties Gema C2004 and Tlaxcala F2000 were settled in three localities from state of Tlaxcala. Analyzed variables were days to flowering and to maturity, plant height, grain yield, incidence of yellow rust in foliage and in ear and incidence and severity of foliar diseases. In the three localities the flour wheat Tlaxcala F2000 variety overcame from 9% to 40% in grain yield to white wheat Gema C2004 variety. The diseases together caused decrease in yield up to 26%. Sportak was the fungicide associated with better disease control, which was seen in greater grain yield with average increases of 26.5 and 29.4% when yellow rust and foliar diseases affected, respectively. The results denote fungicide application to reduce decreases in rainfall wheat production is convenient.

Abstract: Waste electrical and electronic equipment (WEEE) has brought negative effects to the environment produced by the materials that compose them. The proper implementation of management plans of WEEE should integrate measures to prevent, mitigate and correct these affectations. As an initial step, it is necessary to make a diagnosis of the current situation of WEEE management which is the objective of this work. The studied zone was composed by the municipalities of Tampico, Ciudad Madero and Altamira located in southeast Tamaulipas, Mexico. The descriptive analysis of technical and regulatory aspects of the current management system in the study area was developed, including generation rates and analysis of waste streams. Among the main results, the generation of WEEE was estimated in 2040.38 tons/year for 2013, distributed in the municipalities of Tampico with 830.93 tons/year, Altamira with 650.18 tons/year, and Ciudad Madero with 559.27 tons/year. This calculation was estimated using Mexico’s WEEE generation indicators. The analysis of waste streams includes five categories of WEEE, Televisions with 61% of the total generation, followed by sound devices with 18%, personal computers with 17%; mobile phones with 2% as well as fixed phones with 1%. In the study area, reports of Tampico’s municipality indicated that 96 tons of WEEE was collected in the city of Tampico in 2013. In México, the national legislation considers WEEE in the category of waste requiring special handling (WRSH), however, it exists an inadequacy in the environmental laws about the specific classification of this kind of debris that makes their effective management more difficult. No companies who provide a management or treatment operations for WEEE are reported in Tampico, or in the near region. In addition, despite an initial interest for the municipality to attend the WEEE problematic, it exists a lack of sensibility of the population in the absence of environmental education programs.
