Understanding the Interaction of Mesotrione and Atrazine in Redroot Pigweed (Amaranthus Retroflexus)
This dissertation covers an in-depth analysis on the interaction of mesotrione and atrazine and their impact on herbicide resistance stewardship and weed control efficacy. Mesotrione and atrazine are herbicides primarily used in corn, or maize. Herbicide resistance and a reduced number of new …

Plant-plant and plant-insect interactions: Direct and indirect effects of plant neighbors
In greenhouse and field experiments using Amaranthus retroflexus and Chenopodium album, I investigated whether competition and artificial leaf herbivory acted synergistically in depressing plant growth (height, diameter, and vegetative mass) and reproduction (reproductive mass and time of …

Relationships Between Population Variation and Ecological Variability
… of variation were measured in populations of Amaranthus retroflexus and Abutilon theophrasti after four generations of exposure to stress gradients of density, diversity and soil moisture.

Interaction Between Weeds and Insect Pests With Snap Beans (Phaseolus Vulgaris L.)
… the interaction of either redroot pigweed (Amaranthus retroflexus L.) or large crabgrass (Digitaria sanguinalis L.) and bean leaf beetle or potato leafhopper in snap beans (Phaseolus vulgaris L.) cv ""Matador"". The main treatment was emergence time of either redroot pigweed or large …

The impact of allelopathic winter rye (Secale cereale L.) and hairy vetch (Vicia villosa Roth) residues on a vegetable cropping system
… also inhibited weed growth. Redroot pigweed (Amaranthus retroflexus L.) accounted for 60 to 80% of the total weeds. Initial (2 wk) weed control in 1991, was poorest in the disked plots and was similar in RT and CT treatments. In 1992, all treatments were weedy. The RT treatment tended to have …

Evaluation of CGA-136872 and DPX-V9360 for postemergence use in corn
… (Chenopodium album L.) and redroot pigweed (Amaranthus retroflexus L.), particularly with early applications. However, johnsongrass rhizome regrowth prevented full season control of this species with early postemergence applications. Combinations of CGA-136872 with several other herbicides …

Evaluation of anaerobic soil disinfestation using brewers spent grain and yeast inoculation in annual hill plasticulture strawberry production
… (Stellaria media (L.) Vill.), redroot pigweed (Amaranthus retroflexus L.), white clover (Trifolium repens L.), and yellow nutsedge (Cyperus esculentus L.). All ASD treatments significantly reduced weed viability compared to the non-treated control. The yeast amendments enhanced weed control over …

Discovery, surveillance, and management of herbicide-resistant amaranthus spp
Amaranthus species are considered key driver weed species within Midwestern agricultural production systems. Herbicides are often relied upon for the control of Amaranthus spp. In recent years, herbicide resistance at multiple sites of action, such as 5-enolpyruvylshikimate-3-phosphate synthase …
