Westcott's Plant Disease Handbook [Hardcover]

Westcotts Plant Disease is a reference book on diseases which attack plants. Diseases of plants are found on most all plants including trees, shrubs, grasses, forage, fruits, vegetables, garden and greenhouse plants as well as native wild flowers and even weeds. Plant Disease Handbook identifies various types of diseases which are known to invade these plants located throughout North and South America. The recordings include diseases caused by fungi, bacteria, viruses, viroids and nematodes. Causal disease agents are described and illustrated in many cases and diseases and disease control measures are also discussed. A book such as this is never finished since new reports of diseases are continuously reported. This includes new diseases and previously known diseases which occur on both presently recorded plants and on new plants found to be susceptible to diseases. Westcotts Plant Disease provides a reference and guide for identification and control of these plant disease problems.
