Thrips numbers are building up and the second post-winter generation of adults is predicted to be peaking right now. The third generation will probably peak in mid-May (current peak date is projected to be 5/17) but lettuce production will mostly have left the area by then. It looks as though this year has continued the trend we've seen in the recent past, and there hasn't been a major issue with TSWV in the spring lettuce. Virus incidence appears to be generally low across the valley at the moment.
