Tree Fruit IPM Report for April 18, 2022
Evaluating Freeze Damage in Tree Fruit: The subfreezing temperatures on the morning of April 18 may have caused some natural thinning across the state. Any physiological damage that is not visible now will appear as the season progresses. A helpful guide for evaluating fruit damage can be found in the Intermountain Tree Fruit Production Guide.
Tree Fruit Phenology: Tree Fruit Phenology remains advanced, but development is slowing. In southern counties all peach orchards are mid to late bloom. Redhaven was at approximately full bloom on April 6, and was at Petal Fall by April 14. Plums are past shuck fall. Pears are full to late bloom. Red Delicious is just past 50% bloom. Sweet cherries are at about 50% bloom. [Read more…]

Tree Fruit IPM Report for March 28, 2022
Tree Fruit Phenology:
Tree fruit phenology is advanced based on historical observations. In southern counties some early blooming varieties are at pink to about 20% bloom. Redhaven was at bud swell on March 20, about 3 days earlier than the median observation date. Red Delicious was at 1/4″ green tip on March 21, about 10 days earlier than the median observation date. Plums are in bloom and Pears are at green cluster. [Read more…]

Pest Scouting Update – 25 to 150 GDDs Plus Printable resources!
Additional resource: SLF EGG MASS GUIDE – USE FOR TRAINING (click here to download)
We have compiled the GDD resources into one single document – please download and print multiple copies of this for yourself and employees in efforts to best scout for these insect pests. These guides do not dictate when to spray, rather they inform scouting ranges for insect pests, vulnerable life-stages, and overlapping timeframes for multiple troublesome pests.
Please Download these resources:
Nursery and Landscape Pest Scouting Guide 2022 PDF (note this contains conifer pests as well)
Conifer Pest Scouting Guide 2022 PDF
Refer to this post “Obtaining your local growing degree-days” for additional information
We will be making regular announcements throughout the season, however we wanted you to have this beta-version of the compiled growing-degree day information. This will be updated and modified throughout the season – PLEASE let me know what difference you are seeing in the field so we can continue to make this resource better for all of us.
