February 22, 2016

This report covers conditions and observations made between Friday, February 19 and Sunday, February 21, 2016.

The first photo in today’s report provides a down-the-row shot of a Nonpareil and Carmel orchard in the Durham area of Butte County. Taken in the Arbuckle area of Colusa County, the final two photos show the aerial application of fungicide and a down-the-row shot of a Butte and Padre orchard.

Cooler, cloudy weather on Friday and Saturday yielded to warm and sunny conditions on Sunday in the Sacramento Valley. Temperatures never rose above the high 50s on Friday after overnight lows in the mid 40s. Saturday was not much better with overcast skies covering the valley and temperatures not climbing much beyond the low 60s. Sunday saw a break in the weather pattern as lows in the upper 30s quickly gave way to highs in the mid 60s. Bees worked sparsely on Friday and Saturday but were able to work for 7 solid hours on Sunday thanks to the better conditions.

Bloom is winding down quickly in the northern region. The early blooming Sonora has no viable flowers remaining and only 20% still have any petals on them at all. Nonpareil, Monterey, and California-type pollenizers are down to less than 20% flowers presenting for pollination while over one-third of the flowers have completely lost their petals. Carmel is a day behind Nonpareil with 30% open flowers. The late blooming Butte reached maximum numbers of open flowers on Thursday while the Padre reached peak numbers on Saturday. Both varieties have less than half of their flowers presenting for pollination. Orchards continue to exhibit excellent bloom overlap between different varieties.

A second round of fungicide applications have begun as needed. New plantings have started going in the ground after rain last week brought them to a halt.
