Thrips/TSWV Fresno

General Outlook Well, here we are, the 2022 season is open for business. Transplanting is under way (or soon will be). 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.

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.
