When it comes to teaching and tenure it is time to walk the walk.
Institutions should value teaching and service, and not just research, when considering faculty for promotion and tenure
Peach Twig Borer Mating Disruption
Mating disruption became commercially available in the early 1990s, and was adopted by many Utah growers about a decade later. Use of this pest management technology can be daunting due to high up-front costs and monitoring requirements; however, after two to three seasons of use, the cost of mating disruption is the same or even less than conventional pest management
Leafrollers in Fruit Orchards (Lepidopters: Tortricidae)
Leafrollers are a type of caterpillar that may roll or tie leaves together to form a protective shelter. They feed on the leaves and fruits of host plants. This fact sheet describes them, the crop injury they cause, their orchard preferences, monitoring, treatment timing, and management
The Backyard Orchardist – Fruit Pests: Pear
Fire blight is caused by a bacterium called Erwinia amylovora. Pears are very susceptible to fire blight. Blossoms, terminal twigs, and sometimes entire limbs or trees are killed. Environmental conditions favoring infection are warm, rainy days during bloom
Walnut Husk Fly
Walnut husk fly (Order Diptera, Family Tephritidae; Fig. 1) is the most common insect pest of walnuts in Utah. Husk fly larvae (maggots) tunnel in walnut husks, causing them to soften and decay, and stain the shell (Fig. 2). Damaged husks are difficult to remove. If husk fly infestation occurs early in kernel development, nuts may shrivel, darken, become moldy, and drop from the tree (Fig. 3)
An Alternate Method for Setting Codling Moth Biofix
This fact sheet describes an alternate method for setting codling moth biofix that was found to be effective for Utah\u27s fruit production regions. The fixed-biomix method is simpler to implement and easier to explain to growers and crop consultants and can be accessed on line
