Black Medic (Medicago Lupulina) Identification And Control In Residential Landscapes, Michael Caron, Taun Beddes, Corey Ransom
Black Medic (Medicago Lupulina) Identification And Control In Residential Landscapes, Michael Caron, Taun Beddes, Corey Ransom
All Current Publications
Black medic (Medicago lupulina) is an herbaceous winter or summer annual broadleaf landscape weed. This fact sheet provides a weed description and describes suppression and control options.
White Bryony (Bryonia Alba), Taun Beddes, Michael Caron, Jacob Hadfield, Cory Ransom
White Bryony (Bryonia Alba), Taun Beddes, Michael Caron, Jacob Hadfield, Cory Ransom
All Current Publications
White bryony is more than just a nuisance plant. It is an aggressive, perennial vine that threatens riparian ecosystems, agricultural lands, and residential landscapes by destructively smothering vegetation. Additionally, its toxicity poses risks to people, livestock, and pets. Early detection and consistent management are critical to reducing its spread in Utah.
Canada Thistle (Cirsium Arvense) Identification And Control, Caitlin Henderson, Robert Nelson Schaeffer, Corey Ransom
Canada Thistle (Cirsium Arvense) Identification And Control, Caitlin Henderson, Robert Nelson Schaeffer, Corey Ransom
All Current Publications
Cirsium arvense is an invasive perennial weed adaptable to a wide range of habitats. Since its arrival in North America in the 1600s, it has spread throughout much of the country. It has become prevalent in rangelands and disturbed areas in the Intermountain West, displacing native plant species, reducing crop yields, and affecting pasture quality. This fact sheet outlines how to identify Canada thistle, its life cycle, and how to manage it through cultural, mechanical, biological, and chemical control.
Wild Licorice (Glycyrrhiza Lepidota) Identification And Management In Pastures, Jacob Hadfield, Taun Beddes, Michael Caron, Corey Ransom
Wild Licorice (Glycyrrhiza Lepidota) Identification And Management In Pastures, Jacob Hadfield, Taun Beddes, Michael Caron, Corey Ransom
All Current Publications
Wild licorice, also known as American licorice, is a perennial legume native to North America, commonly found in the western United States. Wild licorice reproduces rapidly through seeds and rhizomes, leading to large infestations, particularly in pastures. The low preference of livestock for wild licorice results in overgrazing of other plant species, leaving them at a competitive disadvantage, further promoting the spread of wild licorice and contributing to pasture infestations. This fact sheet reviews the identification and management of wild licorice in pastures.
Parrotfeather (Myriophyllum Aquaticum) Identification And Management In Waterways, Jacob Hadfield, Cody Zesiger, Michael Pace, Mirella Ortiz, Corey Ransom
Parrotfeather (Myriophyllum Aquaticum) Identification And Management In Waterways, Jacob Hadfield, Cody Zesiger, Michael Pace, Mirella Ortiz, Corey Ransom
All Current Publications
Parrotfeather (Myriophyllum aquaticum) is an invasive aquatic plant species that grows in ditches, ponds, lakes, and other freshwater habitats. Due to its aggressive nature, parrotfeather will often take over freshwater settings by creating a thick mat covering that prevents sunlight for native aquatic organisms and inhibits regular water flow. This fact sheet discusses identification and management options.
Wild Parsnip (Pastinaca Sativa) Identification And Control In Residential Landscapes, Michael Caron, Taun Beddes, Corey Ransom
Wild Parsnip (Pastinaca Sativa) Identification And Control In Residential Landscapes, Michael Caron, Taun Beddes, Corey Ransom
All Current Publications
Wild parsnip is a weed that can potentially cause serious injury to gardeners. This fact sheet describes this weed, its lifecycle, and suppression and control options.
Whitetop (Hoary Cress) Control In Residential Situations, Taun Beddes, Michael Caron, Jacob Hadfield, Corey Ransom
Whitetop (Hoary Cress) Control In Residential Situations, Taun Beddes, Michael Caron, Jacob Hadfield, Corey Ransom
All Current Publications
Whitetop (Lepidium draba, formerly Cardaria draba) is a persistent, perennial weed that grows in open, sunny areas. It spreads by seeds and rhizomes, enabling it to spread by several feet in a single season. It is common in wildlands, agricultural, and residential areas. It rapidly spreads into unhealthy lawns, landscape beds, and vegetable gardens. This fact sheet provides information on identification, lifecycle, landscape damage, and suppression and control options.
Identifying And Managing Dyer's Woad (Isatis Tinctoria) In Pastures, Rangelands, And Non-Crop Settings, Cody Zesiger, Jacob Hadfield, Corey Ransom
Identifying And Managing Dyer's Woad (Isatis Tinctoria) In Pastures, Rangelands, And Non-Crop Settings, Cody Zesiger, Jacob Hadfield, Corey Ransom
All Current Publications
Dyer's woad (Isatis tinctoria) was introduced into Utah during the mid-nineteenth century as a source of indigo dye. The plant escaped cultivation and has spread across rangelands, foothills, and other sites throughout the Intermountain West. This fact sheet provides information about identifying dyer's woad and its lifecycle, distribution, and management in pastures, rangelands, and non-crop settings. It includes information about using appropriate herbicides to control dyer's woad and how to apply them.
Identification And Management Of Scotch Thistle (Onopordum Acanthium L.) In Pastures, Rangelands, And Non-Crop Settings, Cody Zesiger, Jacob Hadfield, Kalen Taylor, Corey Ransom
Identification And Management Of Scotch Thistle (Onopordum Acanthium L.) In Pastures, Rangelands, And Non-Crop Settings, Cody Zesiger, Jacob Hadfield, Kalen Taylor, Corey Ransom
All Current Publications
Scotch thistle (Onopordum acanthium) is an invasive species native to Eurasia. It was likely introduced into North America during the late 19th century (Young & Evans, 1969). Due to the plant’s size and prickles, a stand can damage pasture productivity, ruin campsites, or make trails nearly impassable. The thistle also outcompetes desirable plants and greatly reduces forage use by large animals. Since not all thistles are related or alike, it is essential to correctly identify Scotch thistle before making management decisions. This fact sheet provides information about identification, lifecycle and distribution, and management.
