Another book from DK (publisher). Like other DK books, this book is full of high quality photos that illustrate plants' pests & diseases. This book will eliminate the guesswork on what's wrong with your plants or if the insect resting on the leaves are friendly or not.
There was this other book similar to this one, they almost have the same content. They actually have the same title. The reason why we did not pick the other book even though its cheaper was because it listed earthworms as pest. Sometimes earthworms become a nuisance but their benefits outweigh their detriment.
