Garden Pest and Plant Disease Listing - TO

TOAD: This is a small, tailless amphibian desirable in gardens for controlling insects.

TOMATO EARLY BLIGHT: This fungal disease is common in tomatoes and potatoes. It causes irregular circular spots or lesions on stems, leaves, and fruit. The spots usually have a bull's-eye pattern of concentric rings. This disease can be caused by heavy dew or overhead watering. To control, avoid watering overhead, keep plants growing vigorously, rotate crops, or spray with liquid copper.

TOMATO HORNWORM: This large, bright green moth larva has a horn-like hook at one end and leaves black droppings. It eats the leaves and fruit of tomatoes and other vegetables and can rapidly defoliate parts of the plant and scar the fruit. To control, handpick the worms, plant under row covers, release Trichogramma wasps (Go see), or spray with Bacillus thuringiensis (Go see) or traditional insecticides.
