Utilizing Cover Crops To Improve Sustainability Of Conventional Weed Management Programs, Garret Brown Montgomery

Doctoral Dissertations

Research was conducted from the fall of 2014 to the fall of 2016 to evaluate the optimal utilization of cover crops for weed control in no-till environments. Studies included a corn (Zea mays L.) termination timing study to evaluation different termination intervals of cereal rye (Cereal rye L.), hairy vetch (Vicia villosa Roth.), and a combination of cereal rye and hairy vetch cover crops on corn growth and development, an evaluation of a roller crimper for cover crop termination prior to corn study, an evaluation of a roller crimper for cover crop termination prior to soybeans [ …

Alternative Strategies For Weed Control In Creeping Bentgrass, Matthew Thomas Elmore

Doctoral Dissertations

Creeping bentgrass (CBG) (Agrostis stolonifera L.) is the most widely used cool-season turfgrass species on golf course fairways and tees in the United States, but it is tolerant of few post-emergence herbicides. Commercial herbicide development is currently focused on providing superintendents with herbicides that pose minimal environmental impact and can be used effectively at lower application rates than older alternatives. However, few of these products are safe for use on CBG. Several projects were conducted to evaluate alternative strategies to increase CBG herbicide tolerance.

Plants naturally contain enzymatic systems that metabolize xenobiotics. The interspecies variability in these enzymes is …
