How to Manage Pests

Pests in Gardens and Landscapes

Identification and confirmation—Sunscald

Sunscald causes fruit to become brown and leathery on the side exposed to the sun. Black mold may also cause large lesions on fruit, but these are usually covered with a black velvety layer of spores. Fruit affected by late blight also remain firm with brown blotches but those are usually around the calyx and top part of fruit.
