Watering The Landscape: Make It Easier With Evapotranspiration (Et), Candace Schaible, Kelly Kopp, Helen Muntz Dec 2020

Watering The Landscape: Make It Easier With Evapotranspiration (Et), Candace Schaible, Kelly Kopp, Helen Muntz

All Current Publications

The American lawn is our nation’s single largest irrigated “crop” (Lindsey, 2005). In Utah, roughly 65% of our drinking water is applied to residential and commercial landscapes (Center for Water Efficient Landscaping, 2020). Landscapes are typically overwatered, which is why residential and commercial landscape watering is estimated to be one of the largest sources of potential water conservation in the urban setting (Endter-Wada et al., 2008).

Managing Suckers Around Fruit Trees, Samuel Johnson, Teryl Roper, Xin Dai Nov 2020

Managing Suckers Around Fruit Trees, Samuel Johnson, Teryl Roper, Xin Dai

Not only are suckers around trees unsightly, but they can also harbor insect pests like wooly apple aphid and provide points of entry for diseases like fire blight. If suckers are profuse, they interfere with in-row weed management and can absorb systemic herbicides such as glyphosate.

Using Degree Days To Time Treatments For Insect Pests, Marion Murray Mar 2020

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.
