Hey everyone. I am checking out this book as we speak. Its a pocket size book, and it has pictures. It covers weeds, diseases, insects, abiotic factors, and other useful information. I think that I payed somewhere around $15 for it. This book can easily fit into a glove compartment. It's easy enough for a crew to use on their own I should think. Name of the book is: "Turfgrass Problems" picutre clues and management options by, Eva Gussack & Frank S. Rossi, PHD seems like a really good and useful book.
