February 29, 2016

This report covers conditions and observations made between Friday, February 26 and Sunday, February 28, 2016.

Taken in Butte County, the first two photos in today’s report show the jacket stage and nutlet development in the Sonora and Butte varieties. The third photo shows the jacket stage of the Nonpareil variety in the Williams area of Colusa County.

Sunny skies and warm temperatures filled the Sacramento Valley on Friday and Saturday. Overnight temperatures in the low 40s quickly gave way to daytime highs in the low 70s. Skies were clear and winds were relatively calm both days. Daytime highs on Sunday dropped into the upper 60s with some clouds during the morning hours. Bees were able to work well all three days putting in seven solid hours each day on what few flowers remain.

Bloom will conclude tomorrow in the northern region as there were very few viable flowers left in any orchards. The only flowers presenting for pollination are in Butte and Padre orchards in the southwestern area of the region. In the northern part of the region, all other varieties have almost no petals remaining. In the early blooming Sonora variety some nutlets were observed breaking through their protective jackets.

With rain predicted for the end of the week growers that have not made a second fungicide treatment are making that application. Bee keepers are beginning to pull hives out of early blooming fields.
