How to Manage Pests

Pests in Gardens and Landscapes

Tomato spotted wilt virus

Infected plants exhibit bronzing of the upper sides of young leaves, which later develop distinct, necrotic spots. Leaves may be cupped downward. Some tip dieback may occur. On ripe fruit, chlorotic spots and blotches appear, often with concentric rings. Green fruit show slightly raised areas with faint, concentric zones.

Solutions

The tomato spotted wilt virus is transmitted by thrips. Control thrips with applications of insecticidal soap. Removing and destroying infected plants can help control the spread of virus.
