Hemp Diseases and Pests (Cabi)

Here's the perfect recipe for a book about cannabis: use three authors who have spent decades studying cannabis horticulture, combine them with an international publishing company, and give them enough resources to create an oversized book with professional citations, illustrations, and binding.

This perfect recipe has produced a gorgeous new book, HEMP DISEASES AND PESTS - MANAGEMENT AND BIOLOGICAL CONTROL. The authors - Dr. John McPartland, Robert Connell Clarke, and David Watson - are premier marijuana researchers whose credibility and breadth of knowledge are legendary.

McPartland is a medical doctor, botanist and cannabinoid researcher. Clarke is the author of two epic texts, MARIJUANA BOTANY and HASHISH!. Watson runs HortaPharm, the Dutch cannabis breeding consortium supplying specialty cannabis to UK med-pot research projects conducted by GW Pharmaecuticals.

HEMP DISEASES AND PESTS is a fascinating, practical book, and an upcoming issue of CANNABIS CULTURE will give a more complete summary of its features. For the purposes of this brief online review, however, I assure you that this book will significantly increase yield, efficiency and quality for any marijuana grower who follows its advice.

The book includes photos that help growers diagnose dozens of plant dysfunctions, including enemy insects, mites, mammals, and fungi, environmentally-caused problems, overwatering, and nutrient deficiencies. It tells growers how to protect their crops using biocontrols instead of toxic chemicals. It describes ideal soil components, harvesting guidelines, and curing procedures.

Although HEMP DISEASES AND PESTS is not intended as a "grow book" that focuses on lighting, security, and clandestine techniques, its scope, accuracy and detail make it an incomparable textbook that every marijuana grower should have. It is interesting and entertaining, immaculately presented and organized, and features the most innovative and reliable techniques for keeping your plants healthy and happy.

HEMP DISEASES AND PESTS is a large, 251 page, professional book with a professional price. It's well worth it. When I grew my own marijuana, I was often puzzled by plant problems. If I'd had this book, I could have easily eliminated those problems. HEMP DISEASES AND PESTS will likely increase the yield of your garden by at least 50%- if that's not worth, I don't know what is!

This is an invaluable tool for the serious grower. Any experienced gardner will be able to use the information in this book to fabulous advantage. Although highly technical, (the authors go to great lengths to substantiate all the material presented in a scientific manner)the book is formatted in such a way that it can be used by anyone to diagnose and treat pest/disease problems event by event, rather like an encyclopdia. It is thorough and formatted logically and concisely. This is an excellant troubleshooting tool which works exceptionally well with pest and disease encyclopedias in the gardener's library.

Having only been able to get an overview of this imposing tome, I came away thorougly impressed. for by far the most comprehensive book on the subject, this book should become indispensable. in a field dominated by the likes of ed rosenthal and jorge cervantes, it's nice to see a work that's more academic than either e.r. or j.c. are inclined to churn out (not that they don't provide a great service to the public as well!) if you've got the time, and are serious about cultivation, this work will resolve a lot of nagging questions and issues you might have in a professional, well-organized fashion.

This is a monumental effort, 220 page plus book well laid out and researched with heaps of references and an easy to follow index of pests and diseases plus biological solutions as the title indicates. Members may recall that John McPartland in fact all the authors were very helpful to NZHIAI some time back regarding MAF's (Ministry of Agriculture and Fisheries) request for information regarding industrial hemp pests and diseases. By NZ standards this book is quite pricey (NZD 150-00 plus landed) That said I would suggest if you are re serious regarding growing industrial hemp this book will become as it is rapidly for me "Your bible." There is so much information my head is spinning. It is attractively bound and could well become a collectors item. No problems with NZ customs. In a word it is BRILLIANT. A credit to the authors. It can be obtained from the website below. Only took a week to get here.
