Actualmente se conocen más de 50.000 enfermedades que afectan plantas de importancia económica y cada año se descubren otras más. Estas enfermedades causan pérdidas económicas, lo que provoca una reducción en el rendimiento y la calidad del cultivo. Generalmente los agricultores y profesionales del agro tiene dificultades para diagnosticar correctamente los patógenos que las causan, usando productos agrícolas inapropiados de amplio espectro y categoría toxicológica alta para su control, produciendo un impacto negativo en los aspectos ambientales, económicos y sociales. Es por ello que se elaboró esta guía ilustrada que ayuda a identificar 50 enfermedades causadas por cromistas, hongos y nematodos fitoparásitos en cultivos hortícolas. Se incluye una descripción detallada del patógeno, sintomatología de la enfermedad que causa, factores epidemiológicos que lo favorece y las pérdidas económicas que puede causar. Además, se complementa con claves taxonómicas que permiten a los profesionales estudiar las características inherentes de cada uno de los patógenos identificados e ilustrados.

This is the story of Chicago and how it grew. In a little over a century it rose from a mere frontier outpost to become one of the great cities of the world. No single book can possibly encompass the immense scope of this development or convey the endless diversity of the life of Chicago's people. But with the help of the camera it is possible to capture many dimensions of this extraordinary story. This volume, however, which comprises over 1.000 pictures and 50 maps, tries to do more than show physical development - it attempts to suggest how the city expanded and why it looks the way it does. Because it asks different questions, this book differs markedly from other "pictorial histories" of American cities. Instead of emphasizing society and customs, this volume deals with the physical conditions of life. In place of the conventional interest in "founding fathers" and leading families, it is more concerned with street scenes and ordinary people. Without neglecting downtown, it also reaches into the residential areas and neighborhood shopping centers. Moreover, this volume is concerned with suburbs and "satellite" towns as well as the historic city.
