This report covers conditions and observations made on Thursday, February 25, 2016.

The first two photos in today’s report for the northern region illustrate the jacket stage and nutlet development in the Nonpareil variety in the Arbuckle area of Colusa County, followed by the Butte variety in the Dunnigan area of Yolo County. The third photo illustrates the final stages of bloom in an Independence orchard in the Chico area of Butte County.

The Sacramento Valley enjoyed more of the same warm weather Thursday, with morning lows in the mid 40s and daytime highs reaching into the mid 70s. Weekend weather forecasts are calling for continued warm weather, with rain and increasing winds likely Friday night.

Throughout the northern region, observers are reporting that bloom is at or near the ending stages in the Nonpareil, Sonora and California-type varieties, while trace amounts of bloom can be found in the Carmel and Monterey varieties. Butte and Padre varieties still have up to 30% of viable bloom in some areas, mainly along the west side of the valley. While nutlets can be seen poking through their jackets in earlier varieties, only trace amounts have been reported breaking free from their jacket in the Sonora variety.

With rain forecast for Friday evening, growers are busy applying fungicide treatments to help prevent disease caused by excess moisture. In areas of elevated naval orangeworm pressure from last year’s crop, growers are working to blow and shred mummy nuts to help keep the insect pressure lower for the upcoming crop. Crews are working hard to plant new orchards and replacement trees during this window of nice weather before the upcoming rain.
