Thrips/TSWV Fresno

General outlook A week of 100+ F daily maximum temperatures and warm nights will give thrips development a boost over the next week. A gradual return to mid 90's highs is expected by the second week of June. The current mini heat wave won't be enough to cause any significant mortality in thrips.

We're seeing some early TSWV in areas of western Fresno Co.

General outlook 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: Things have warmed up recently. Our reference weather station for Fresno is running about 3 days ahead of last year and a week ahead of the 30-year average for heat accumulation, so far this season.
