There has been a lot of tomato spotted wilt virus (TSWV) found recently in our area. TSWV is a virus that is spread by at least seven different kinds of tiny insects known as thrips. It takes only a few minutes of feeding for a tomato plant to become infected, and once TSWV is acquired, there is no cure.
TSWV is sporadic in nature with some years having high disease pressure and other years having relatively little disease pressure. The virus has locally been found in tomatoes, tobacco and peppers. Because of the unpredictable nature and the broad host ranges of thrips, controlling TSWV can be very challenging.
