Almonds are susceptible
to a lot of diseases.
This presentation covers the basics principles of plant disease with specific examples from the almond production system. Future videos will discuss the specifics of disease management for the major flower, fruit, and foliar pathogens of almonds.

Preventing spring diseases in almond
Petal fall through the first few weeks of nut development is a critical time for disease management. During this period, the almond fruit, newly emerged leaves, and senescing tissues are susceptible to many diseases. These include jacket rot, anthracnose, brown rot, leaf blight, shot-hole, scab, and with Mediterranean varieties, red blotch.
Frost damage to almonds
Almonds are susceptible to frost once they begin to flower. As a flower progresses through bloom (i.e. dormant > pink bud > full bloom > petal fall > small fruit), it becomes more susceptible to cold temperatures. Frost killed flowers/small fruits are easy to identify as the color of the tissue changes.
Operational expense savings during almond bloom
The period of bloom has become increasingly expensive. Pollination services, fungicides, application expenses have increased rapidly over the past few years and this has impacted orchard profitability.
2023 Bloom Considerations
The weather during almond bloom can vary from day-to-day. This creates challenges with farm operations, but also changes how the tree adapts to the weather.
