Hemp and cannabis, both belonging to Cannabis sativa, have emerged as some of the most valuable crops because of their multiple functionalities - industrial, medicinal, and recreational uses. Like all other crops, they are at risk of diseases and pests. In certain cases, an entire hemp field can fail due to unexpected disease. As a new and highly regulated crop, research on Cannabis crop diseases is scarce, and the science of plant diagnostics is not well covered in the literature. Taking hemp/cannabis as a model crop, the book illustrates how to diagnose a disease problem and how to manage it effectively. It presents real disease cases encountered during crop production, and explains methods of diagnosis, both in the field and in the lab, in order to find out the cause(s).

Hemp is enjoying a worldwide resurgence. This book combines a useful review of the hemp pest and disease literature published over the past 50 years, with up-to-date information on modern biological control techniques. Each pest and disease organism is presented in the same format, covering range and economic impact, symptoms, life history, diagnosis, and both new and old techniques for biological control and chemical control. Easy to use keys are included for rapid identification of the most common pests. Introductory chapters describe the general principles of plant protection, requirements for healthy plant growth, and taxonomy of parasites and pathogens.

This book allows cannabis growers to quickly and easily identify diseases, deficiencies and pests on their crops. It provides you with the symptoms and causes of the identified disease as well as the treatments that allow you to eradicate the disease and prevent its futuristic reappearance.The book contains an identification key that allows you to quickly and easily identify diseases, deficiencies and pests in your cannabis / marijuana crops.
