This report covers conditions and observations made on Monday, February 16, 2015.

Taken on the East side of Stanislaus County, today’s photos for the Northern San Joaquin Valley show the petal fall and jacket stage of Sonora, followed by the beginning of petal fall in a Nonpareil planting. Finally we see a panoramic view of a Nonpareil, Carmel, and Aldrich planting exhibiting good bloom overlap.

The Northern San Joaquin Valley saw a continuance of early morning, patchy fog, which gave way to sunshine and warm temperatures as the day progressed. Temperatures again rose rapidly from early lows in the mid 40’s to afternoon highs around 70 accompanied with a light breeze making for a beautiful day. Once again, the bees were given plenty of working hours to pollinate the orchards. Observers reported 7-8 hours of excellent bee activity.

The Sonora variety reached its peak over the past couple days, and has began rapidly shedding petals, leaving the nutlets to develop within their jackets. Nonpareil and the earlier California varieties are near or at their respective peak bloom. Later blooming varieties, such as the Carmel, are progressing quickly toward their peak, and are continuing to be timed well with the Nonpareil. Across the board, bloom timing and overlap has been ideal within different plantings. Butte and Padre varieties are beginning to come on strong, with measurable bloom in both varieties. Some advanced planting are presenting 50% to 60% open flowers. However, on average, Butte and Padre plantings are showing approximately 25% to 30% open flowers.

Many growers in the Northern San Joaquin Valley have begun applying fungicide treatments, while others are holding off as much as possible. In areas that have coupled consistently light winds with the lingering heat, and no fog, growers believe the climate is not conducive to fungal disease.
