Recent rain & #ElNino conditions create favorable conditions for aerial Phytophthora pathogen. Although it doesn't kill the #almond tree, the disease causes branch dieback that requires significant additional work & expense for growers. #CAwx @FloTrouillas tinyurl.com/49jmp38e

Calosphaeria canker of sweet cherry occurs worldwide and can be easily diagnosed in the field by removing the bark periderm and looking for the typical perithecia of Calosphaeria pulchella occurring in circinate groups. ⁦@ucanr⁩ ⁦@UCIPM⁩

NOAA Sac( weather.gov/sto/) forecasts a hard freeze for the next 2 mornings (Mar 1-2) in North/central Sac Valley. Growers w sprinkler irrigation should start water when wet-bulb temp is above the critical temp. Critical temp/bloom stage info at: sacvalleyorchards.com/almond…
