Question of the Week: TSWV

Last week the question was:  What is wrong with this tomato?


This tomato is showing symptoms of Tomato Spotted Wilt Virus (TSWV).  TSWV is vectored by thrips and can infect a number of crops like tomatoes, peppers, tobacco, and peanuts.  Since it is a virus, no fungicides are available to control it and thrips control is not reliable either as it doesn’t take long to transmit.  Resistant varieties are the best means of reducing TSWV incidence.  For more information, take a look at this APS page.


Here is this week’s question:  What is this weed that was found in a vegetable field?
