Thrips/TSWV status in Yolo & Colusa

General Outlook Well, here we are, the 2022 season is open for business. The first half of the winter was wet and cold, but since the turn of the year, we have seen next to no precipitation in the region. Temperatures have been more or less normal for the time of year.

General outlook A run of 100+ F daily maximum temperatures and warm nights will likely accelerate thrips development over the next week or more. A return to low 90's highs is expected in the second week of June.

General outlook Planting is underway in the Dixon area but a lot of crop area has only just gone in the ground. We're heading into to a run of slightly warmer weather which will last about a week and accelerate thrips development.

General situation: We're a little bit late getting the clock started this season, but here is the first post of the 2021 thrips/TSWV risk evaluation.

General situation: Despite things warming up recently, our reference weather station for Yolo/Colusa/Solano is still behind the last couple of years and the 30-year average for heat accumulation, so far this season.
