Q: I’m searching for a good garden pest management guide, preferably one that includes pictures of the pests and organic pesticides.

A: Rodale’s Pest and Disease Problem Solver is quite good. I’m glad you are interested in identifying the insect before you decide on controls. In my experience, knowing exactly what insect or disease you have is 80 percent of the pest control battle. Many beneficial insects look similar to pest insects, so having a positive ID means you won’t be tempted to apply a pesticide without regard to its effect on beneficials.
