Labeling of nonstructural carbohydrates in winter wheat stems
Fructans are polymers of fructose, which contain a terminal or subterminal glucose moiety. The biosynthetic pathway for the levan-type of fructan, found in wheat, has not been elucidated. These compounds are a significant ... -
Management and epidemiology of Cytospora perennial canker, Cytospora plurivora, in western Colorado
Cytospora canker is a ubiquitous disease in deciduous fruit tree systems in western Colorado. The research conducted herein, explores the host-pathogen-environmental framework which has enabled Cytospora plurivora to thrive ... -
Investigating fluroxypyr resistance in Bassia scoparia
Synthetic auxin herbicides are designed to mimic indole-3-acetic acid (IAA), an integral plant hormone affecting cell growth, development, and tropism. Recent developments in synthetic auxin herbicide research have produced ... -
Dataset associated with “Investigating the origins and evolution of a glyphosate-resistant weed invasion in South America”
The global invasion, and subsequent spread and evolution of weeds provides unique opportunities to address fundamental questions in evolutionary and invasion ecology. Amaranthus palmeri is a widespread glyphosate-resistant ... -
Curious case of chemotaxis in soft rot Pectobacteriaceae, The
Soft rot Pectobacteriaceae, Dickeya and Pectobacterium, are notorious for causing blackleg and soft rot diseases on more than 50% angiosperms such as potato, tomato, carrot, cabbage, and rice. In the United States, soft ... -
Biology and management of blackleg disease of potato caused by Dickeya dianthicola (ME23)
Potato is the most commonly consumed vegetable in the United States, where people each an average of 49.2 pounds per person per year. About 80% of potatoes in the US are produced in Idaho, followed by Washington, Wisconsin, ... -
Investigating the impact of soil type, soil moisture, and soil surface residue cover on the efficacy of Diflufenican
Diflufenican is a pre-emergent and early post-emergent herbicide that inhibits phytoene desaturase, an essential enzyme in the biosynthesis of carotenoids. It has been used effectively in overseas markets such as Europe ... -
Bee diversity and abundance under a grazed cover cropping management system in eastern Colorado and southwestern Nebraska and evaluating the role of beekeeping education and management on honey bee hive overwintering success in Colorado
Bee pollination is essential to the production of many valuable crops in addition to facilitating the reproduction of non-crop flowering plants in the environment. Managed and wild populations of bees face unique and ... -
Investigation into potential non-target effects from the use of emamectin benzoate trunk injections for the management of emerald ash borer (Coleoptera: Buprestidae)
A potentially significant source of increased conflict in Colorado involving insecticide use in urban areas and honey bees (Apis mellifera L.) recently emerged with the establishment of the invasive species emerald ash ... -
RNA sequencing identifies genes putatively involved at the aphid-Buchnera symbiotic interface
In aphids, the supply of essential amino acids depends on an ancient nutritional symbiotic association with the gamma-proteobacterium, Buchnera aphidicola. The endosymbiont converts abundant non-essential amino acids into ... -
Combined effects of warming and drying on a temperate-to-boreal forest ecotone exert additive changes on soil microbiome structure and diversity
The soil microbial community is an important mediator of many ecosystem functions, so understanding dynamics under climate change. These responses could be more robust in transitional zones such as the temperate-to-boreal ... -
Using indaziflam for integrated weed management in managed and natural ecosystems
Indaziflam is a relatively new herbicide for natural area weed management. It is unique because it inhibits cellulose biosynthesis and it controls annual weeds as the seeds germinate. This soil active herbicide provides ... -
Integrated pest management of tomato/potato psyllid, Paratrioza cockerelli (SULC) (Homoptera: Psyllidae) with emphasis on its importance in greenhouse grown tomatoes
The tomato (potato) psyllid, Paratrioza cockerelli (Sulc), has developed into a key insect pest of greenhouse tomatoes of western North America and few options have been available for its management. A series of trials ... -
Dataset associated with “Genomic‐based epidemiology reveals independent origins and gene flow of glyphosate resistance in Bassia scoparia populations across North America"
Genomic-based epidemiology can provide insight into the origins and spread of herbicide resistance mechanisms in weeds. We used kochia (Bassia scoparia) populations resistant to the herbicide glyphosate from across western ... -
Environmental predictors of annual incremental Populus deltoides growth, and riparian forest structure of the South Platte River in northeastern Colorado
Riparian forests are biologically diverse systems that provide essential ecological services, such as flood attenuation, bank stabilization, habitat, nutrient cycling, temperature regulation, etc., for the landscapes they ... -
Aspects of weed resistance to auxinic herbicides
Synthetic auxins have been widely used for selective control of broadleaf weeds since the mid-1940s. After more than 70 years using synthetic auxin herbicides, there are 41 different resistant species reported. Weed ... -
Understanding weed biology and herbicide resistance to improve weed management
Weed management is essential in agriculture, natural areas, and rangelands. Weed control has mainly relied on herbicides. These chemical compounds are a low-cost option, easy to apply, and very efficient to eliminate weeds. ... -
Investigations into the nature of the potato psyllid toxin
The potato or tomato psyllid, Paratrioza cockerelli (Sulc) (Homoptera: Psyllidae) is a pest of many solanaceous crops in the western U.S. and causes a disease in potatoes and tomatoes known as "psyllid yellows". The disease ... -
Diet matters in the growth of captive African white spotted assassin bug Platymeris biguttatus (Hemiptera: Reduviidae)
The African white-spotted assassin bug, Platymeris biguttatus (L. 1767) (AWSAB) is a large bodied true bug, popular in both zoo and hobbyist living collections. The popularity of this species can be attributed to its high ... -
Whole genome analysis of the koa wilt pathogen (Fusarium oxysporum f. sp. koae) and development of molecular tools for early detection and monitoring
Pathogenic and non-pathogenic Fusarium oxysporum are morphologically indistinguishable from each other. Pathogenic F. oxysporum f. sp. koae (Fo koae) is a limiting factor for low to mid elevation, below 610m (2000 ft), ...
