Managing Soil Ph For Crop Production In Calcareous-Alkaline Soil, Cody Zesiger, Jody Gale, Matt Yost, Grant Cardon
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 …

All Current Publications
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.
Extending The Garden Season, Taun Beddes, Michael Caron, Sheriden M. Hansen, Jaydee Gunnell
Extending The Garden Season, Taun Beddes, Michael Caron, Sheriden M. Hansen, Jaydee Gunnell
All Current Publications
Many homeowners have the dream of growing fresh vegetables year-round. Unfortunately, in colder climates, this is only possible using a complete greenhouse with supplemental heating/cooling and lights. Greenhouses can be excessively expensive to maintain and heat, making them impractical for most homeowners. This is not only due to cold winter temperatures but shorter day lengths and lower available light that must be offset artificially. There are practical, less expensive ways to obtain self-grown produce earlier and later in the growing season, though, by using season-extending techniques. These include using equipment such as cold frames, high tunnels, low tunnels, floating row …
Billbugs In Turfgrass (Sphenophorus Spp.), Desiree Wickwar, Ricardo Ramirez
Billbugs In Turfgrass (Sphenophorus Spp.), Desiree Wickwar, Ricardo Ramirez
All Current Publications
Billbugs are weevils, a type of beetle, in the genus Sphenophorus. At least 10 billbug species are known pests of turfgrass and can be found in both warm and cool season turfgrasses throughout the United States. Though billbug adults do feed on the leaves of turfgrasses, it is the larvae that cause visible damage. Larvae feed within the stems and on roots of grasses, leading to the development of yellow or brown patches, with the potential to escalate into large patches of dead turfgrass. Billbug management in turfgrass presents a number of unique challenges, but early monitoring and informed integration …

Irrigation System Maintenance, Candace Schaible, Kelly Kopp, Jennie Hoover
All Current Publications
Irrigation system maintenance is necessary to ensure the most efficient use of the water that is being applied. Efficient irrigation is important because over two-thirds of the total water used in the average Utah home is applied to the landscape. With the natural drought cycles that occur in Utah and the growing population, efficient water use is critical. These maintenance recommendations will help you evaluate your irrigation system before using it each spring and also throughout the growing season.

A great garden starts with healthy soil. In Utah, there are unique considerations for creating and maintaining healthy soils. Native Utah soils are relatively low in organic matter. One of Utah’s most troublesome, pH-related deficiencies is iron chlorosis, a deficiency of plant-available iron. Soil salinity easily increases in Utah. This fact sheet addresses these challenges to help gardeners transform garden soils from brutal to beautiful!
Alfalfa Weevil In Utah, Kaitlin Rim, Joseph Clarine, Steven Price, Ricardo Ramirez
Alfalfa Weevil In Utah, Kaitlin Rim, Joseph Clarine, Steven Price, Ricardo Ramirez
All Current Publications
The alfalfa weevil is a major pest throughout Utah. It is a beetle with one generation per year. Eggs hatch in the spring, and the grub-like immature weevils (larvae) feed by chewing on the alfalfa foliage. In high numbers, alfalfa weevils can cause severe damage to Utah alfalfa. In any given year, however, the weevils are few enough in number in many fields to cause only minor damage. Monitor larval populations in early spring using sweep net or stem count methods. Insecticide resistance can be reduced by spraying only when needed, properly timing sprays, and rotating between modes of action.

Using Degree Days To Time Treatments For Insect Pests, Marion Murray
All Current Publications
Insecticides that are applied for a perennial insect pest based on a calendar date often result in poor insect control and a waste of resources. Insect activity varies from year to year depending on weather. For example, in Logan, Utah, eggs of the apple pest codling moth began hatching on May 15 in 2005, May 5 in 2006, and April 30 in 2007.

Community-Wide Grasshopper Control, Marion Murray
All Current Publications
Springtime, while grasshoppers are still nymphs, is the best time for communities or neighborhoods to work together to suppress grasshopper populations. Treating as wide an area as possible is the key to success. When grasshoppers become adults, they can travel great distances and may not remain in one area long enough for an insecticide to be effective.

Soft Scales In Utah, Marion Murray, Erin W. Hodgson
All Current Publications
Soft scales are insects in the family Coccidae and are closely related to armored and felt scales and mealybugs. Scales are fluid feeders with piercingsucking mouthparts that remove plant phloem or sap. Most life stages are immobile because they anchor their mouthparts into host tissue. They are difficult to control because of their waxy covering, seasonal abundance, and high fecundity.
