Thrips/TSWV status in Yolo & Colusa

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.

General situation Based on limited local travel, it looks like planting in the Dixon/Vacaville Area is past its peak, if not done for the season. The weather is starting to settle into its summer pattern and we are looking at temperatures building from a relatively cool spring.
