Both a meticulous review for crop scientists, and a practical guide for growers, this book is a classic in the literature on hemp diseases and pests. Since publication of the first edition in 2000 hemp and cannabis cultivation has continued to expand, accompanied by a rise in the incidence and severity of plant pathogens and pests. This new edition integrates the new wave of cannabis research with historical information previously not available in English. It is a compendium of information on insect pests, fungal and oomycete diseases, virus and mycoplasma diseases, bacteria, nematodes, assorted parasitic plants, and other pests (including mites, molluscs, birds and mammals). Chapters have been grouped into sections, organized by parts of the plant affected - roots, shoots, flowering tops etc. - to make it easier for the reader to identify and troubleshoot pest and disease problems. Each pest organism is described, with ample images of signs and symptoms.The final section provides an extensive overview of methods of controlling pests and disease. Cultural, mechanical and biological control are highlighted, along with biorational chemicals. As before, the focus is on growing a healthy crop using sustainable methods. This comprehensive text is essential reading for researchers in plant pathology, entomology, botany, horticulture, and hemp cultivators and growers.
