Managing Soil Ph For Crop Production In Calcareous-Alkaline Soil, Cody Zesiger, Jody Gale, Matt Yost, Grant Cardon
All Current Publications
In semiarid soils of the Western U.S., altering soil pH is not easily accomplished nor straightforward. Utah’s soil pH range can be 1,000 times more acidic or alkaline than neutral (7.0) pH soils. In semiarid regions, typical high-pH soils are also calcareous, meaning there is a large amount of solid calcium carbonate (lime) in the soil. When soil-acidifying amendments are added to these soils, the lime dissolves and counteracts any of the applied soil-acidifying amendments. This fact sheet explains how to identify whether crop symptoms are related to soil pH, how to perform an in-field test for soil pH buffering …

Poplar Borer, Marion Murray, Ryan Davis
All Current Publications
The poplar borer is the most commonly submitted wood borer found in aspens and other poplars in Utah. While large trees are seldom killed by this pest, it can cause the decline of trees, weakening of branches or the bole (which promotes wind breakage), and allows the introduction of pathogens. This fact sheet describes poplar borer life cycle, damage, and control.

The poplar bud gall mite belongs to the eriophyid mite family. These mites are microscopic and about one-fourth the size of a spider mite. Adults are about 0.2 mm in length, reddish, and spindle-shaped. This fact sheet reviews poplar bud gall mite biology and habits, damage, and control.

Red Firebug, Kate V. Richardson, Erin Hodgson
All Current Publications
Red firebugs, Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae), are true bugs with vibrant red body and wing coloration. These insects are native to central Europe, but are also found in western Siberia, southwestern Mongolia, India and northwestern China. This fact sheet describes red firebug, host plants, nuisance behavior, and management.

Boxelder Leafroller, Marion Murray, Ryan Davis
All Current Publications
The boxelder leafroller, Archips negundana, is a pest of boxelder and other trees and shrubs in parts of the United States and Canada and is commonly found in Utah. Boxelder is the primary host, but damage can also occur on raspberry, birch, elderberry, white elm, and various shrubs.This fact sheet provides information on the boxelder leafroller's life cycle, symptoms of damage, and control methods.
Implementing Bos Indicus-Influenced Cattle In Utah For Hybrid Vigor, Reganne K. Briggs, Matthew D. Garcia
Implementing Bos Indicus-Influenced Cattle In Utah For Hybrid Vigor, Reganne K. Briggs, Matthew D. Garcia
All Current Publications
Crossbreeding is a tool that cattle producers have used for decades. Hybrid vigor is one of the products of crossing breeding. One way to maximize hybrid vigor is by introducing Bos indicus genetics in a herd. Santa Gertrudis cattle are a great option for introducing Bos indicus genetics.

The larval stage of the carpenterworm, Prionoxystus robiniae is a wood-boring insect that affects various ornamental trees. Unlike most other wood-boring pests of ornamentals, which are mostly beetle larvae, the carpenterworm is a caterpillar belonging to the moth family Cossidae.

Emerald ash borer (Order: Coleoptera: Family Buprestidae) (EAB) is an invasive wood-boring insect that infects the true ash species (Fraxinus spp.). EAB is native to parts of China, Korea, Japan, Taiwan, and small areas of Russia and Mongolia. EAB was first discovered in North America in June 2002 near Detroit, Michigan, and Windsor, Ontario, Canada, and is thought to have arrived to North America via infested wood packing material. EAB is generally established in an area for several years before it is detected and can spread over large areas through active flight and human-mediated dispersal.
