Researchers in plant pathology, entomology, botany and horticulture. Hemp cultivators and growers.

This new edition integrates the new wave of Cannabis research with older information never before translated into 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). The contents have been grouped into sections, in order to make it easier for the reader to identify and trouble-shoot their pest and disease problems. For example, the section on arthropod pests is divided into chapters depending on which part of the plant is affected, e.g. insects and mites that suck fluids; insects that chew flowering tops; insects that chew stalks and branches; insects that chew leaves; and insects associated with young seedlings and roots. Similarly, the section on diseases contains chapters on flowering top diseases; wilts, blights and root rots; leaf and stalk diseases; damping off diseases; and epiphytes and endophytes. The final section provides an extensive overview of the biological, natural and chemical solutions to the pests and diseases of hemp, with details on products, application methods and dosages. The text is structured to serve both technical and general readers: general information in early chapters provides a conceptual framework for technical information presented later in the book.
