From Publishers Weekly Written by various regional plant pathology experts， this companion volume to Natural Insect Control addresses numerous diseases that affect plants in all areas of the country. Not surprisingly， all the authors deem prevention the best cure， and they outline preemptive methods for ornamental plants， vegetables， turf grass and trees. The section on Nine Keys to Disease Prevention offers gardeners advice beyond the simplistic， familiar tips by discussing how plants react to diseases and the stages at which plants are most vulnerable to problems. The experts discuss disease identification and the difference between bacteria， viruses， fungi and nematodes. Problems caused by such environmental problems as pollution， faulty moisture (excessive or inadequate)， chemicals and nutrients' availability in soils also merit attention. In addition to narrative chapters， the book contains a lengthy section of charts detailing specific problems， their prevention， and numerous natural controls such as Neem oil and creative uses of vinegar， baking soda and compost tea when prevention alone is insufficient to deter insects disease. Illustrations of diseased plants， a list of suppliers， organized by region， for disease-resistant plants and for biological control substances， as well as an informative reference source for additional information， increase the value of this practical book.
