Armyworm And Cutworms In Turf, Erin W. Hodgson
All Current Publications
Armyworms and cutworms can be found all over the United States, with at least three species found in Utah. These insects belong to a large group of night-flying moths in the family Noctuidae. Although not new pests to turfgrass, armyworms and cutworms are often ignored, and plant health decline is confused with drought stress, fungal disease, or other insects.

All Current Publications
Cranberry girdler, Chrysoteuchia topiaria, can be found throughout the U.S., but is particularly damaging to turfgrass seed production areas in the Pacific Northwest. This insect was first detected in northern and northeastern Utah during the early 1980’s. Larvae prefer cool-season grasses, such as Kentucky bluegrass, bentgrass and fine-leaf fescues. In addition to causing significant damage to turfgrass, it is recorded as a pest of other grasses, cranberry, Douglas fir, and true firs.

All Current Publications
The term “sod webworm” refers to an insect complex of more than twenty different grass-infesting species. Adult sod webworms are pyralid moths, but are more commonly referred to as “snout moths” because their mouthparts are projected forward (Fig. 1). Sod webworms are distributed through the U.S., and at least seven different species occur in Utah (Table 1).

All Current Publications
Pantry pests are insects that infest whole or processed food in the home. Infestations can start out with just a few insects, but a population can quickly surge if given a proper food source and a place to reproduce. Immature and adult insects are typically brought into a home in grain-based products.

Boom Sprayer Calibration For Pesticide Applications, Richard Beard, Howard M. Deer
All Current Publications
To protect your investment in agricultural pesticides, a boom sprayer should be calibrated at the start of the season and whenever application conditions change. Also, sprayer output should be periodically checked throughout the season to assure proper application rate. Although boom sprayers are calibrated in a variety of ways, each method utilizes the measurements of nozzle flow rate and equipment travel speed.
