Organic Pest & Disease Control: How to Grow a Healthy, Problem-Free Garden by Barbara Ellis
This book is helpful in diagnosing garden problems, as well as for researching choices in organic control and prevention. The author utilizes sketches, rather than photos, to aid in identification. The sketches are very well done, with lots of detail. They show the actual size of the insect to gain perspective.
