Peach Problems Seen at Harvest

Peach harvest is on, and we’ve seen a variety of fruit damage, ranging from wind injury, powdery mildew, coryneum blight, earwigs, birds, and more.  Check out the photo gallery to identify what you may be seeing during harvest.


Commercial Growers:  Workshop on conserving beneficial insects, Sept 28 in Kaysville

Lacewing larvae are voracious predators, but the adults need pollen and nectar to survive.

WhatThe Xerces Society and the Utah IPM Program are hosting a workshop on conservation biological control, covering:

  • Identification of predators and parasitoids that attack insect pests.
  • Recognizing the habitat needs of beneficial insects.
  • Design and implementation of habitat improvements, including site preparation, insectary strip plantings, hedgerows, beetle banks, and more.
  • The current best management practices that minimize land-use impacts on beneficial insects and mitigate exposure to insecticides.

When:  Thursday, September 28

Where:  Kaysville Education  Center and Farm

HowRegistration is $45 and includes a packet of materials from the Xerces society, including their book, Farming with Native Beneficial Insects.

Commercial Growers:  Watch for the 2017 IPM Tree Fruit Survey in the Mail

The Utah IPM Program is working with the Utah office of the National Agricultural Statistics Service to determine the use of IPM in tree fruits, and how it is affecting profits.  Be on the lookout for the envelope from NASS, and please be sure to fill out and return the survey!  The results will help the IPM Program to continue to serve the needs of our fruit growers.

New Fact Sheet on Leafroller Pests

Obliquebanded leafrollers feed on foliage and fruit.

Entomologist, Diane Alston, and Marion Murray conducted a 2-year project to identify the primary leafroller species causing damage to Utah orchards.  Obliquebanded leafroller was the most common, primarily causing injury to tart cherries, and contaminating tart cherry harvest bins.
