Book excerpt: Este libro plantea, de un modo comprensible, los aspectosmás importantes a considerar en el control de plagas y enfermedades forestales. Los agentes nocivos que causan enfermedades a las plantas leñosas en el medio forestal pueden ser bióticos (patógenos) o abióticos, ya sean estos por causas naturales (vientos, incendios, etc.) o bien debidos a las actividades humanas directas (podas, deforestaciones, etc.) e indirectas (contaminaciones). Diferentes animales invertebrados (insectos, ácaros, etc.) actúan como parásitos de árboles y arbustos, formando plagas en el monte cuando eluden los mecanismos naturales que controlan sus poblaciones. El primer capítulo estudiará los agentes que causan daños a las plantas forestales. En el segundo capítulo se analizarán los productos y tratamientos fitosanitarios, así como su peligrosidad para la salud humana o el medio ambiente y los residuos generados por ellos. Los diferentes equipos de aplicación fitosanitaria varían según el método que utilizan para llevar a cabo el tratamiento, así como por la naturaleza física de cada producto químico empleado: sólido-líquido-gaseoso. Los distintos estados físicos en los que se pueden distribuir los productos químicos aplicados a la sanidad vegetal, dan lugar a diversos equipos de tratamiento fitosanitario, que serán tratados en el tercer capítulo. Los productos fitosanitarios tienen la consideración legal de sustancias químicas peligrosas y su aplicación en los montes ha de seguir la normativa vigente respecto a la correcta gestión de los residuos generados y la protección a la salud humana y el medio ambiente, cuyo incumplimiento daría lugar a infracciones y sanciones. El cuarto capítuloabordará esta materia. El quinto y último capítulo transmite los conocimientosbásicos necesarios para estudiar la lucha biológica contras las plagas forestales, así como su normativa.
