How to Manage Pests

Pests in Gardens and Landscapes

Spotted wilt virus

Symptoms on plants infected with spotted wilt virus include overall yellowing (chlorosis), dead spots on leaves or terminal shoots, and general stunting. Fruits show chlorotic spots, red and/or green areas surrounded by yellow halos, and concentric rings that may become necrotic. Spotted wilt virus is transmitted by various species of thrips.

Life cycle

Solutions

Spotted wilt is not usually a serious problem in gardens. Control nearby weeds, which are reservoir hosts of the virus and thrips. Destroy infected plants. The use of insecticides to control thrips will not reduce their numbers enough to eliminate virus spread.
