Three essays on the economics of pesticide use
(University of Missouri--Columbia, 2022)
, the adoption of organic pesticides in lawns and gardens is examined. A multinomial logit model is applied to analyze factors affecting adoption versus being in distinct non-adopter categories using a dataset from a survey of 661 residents in Missouri...
Northern bobwhite brood ecology and population dynamics in southwest Missouri
(University of Missouri--Columbia, 2020)
in southwest Missouri. My dissertation objectives were to: (1) Examine the influence of cover type, management, and weather on juvenile bobwhite body condition; (2) Estimate bobwhite juvenile survival from hatch as a function of herbaceous cover, habitat...

practice of cover cropping and no-till to improve belowground pest management. Food security in the future will rely on successful integration of sustainable management practices in agricultural systems to balance productivity and broader ecosystem...
Quantifying neonicotinoid concentrations in Missouri wetlands, their driving factors, and the potential effects on the reliant avian community
(University of Missouri--Columbia, 2018)
detected in Missouri wetlands may be detrimental to aquatic insects and wetland dependent taxa at different spatial and temporal scales. Managers should consider taking reasonable measures to limit the potential contamination of wetlands by neonicotinoid...
Assessing Missouri soybean fields for azoxystrobin resistant cercospora sojina

Behavioral responses of drosophila suzukii (diptera: drosophilidae) to olfactory and visual cues
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Selected fruit and leaf volatiles were assessed to determine their attractiveness to Drosophila suzukii Matsumura (Diptera: Drosophilidae). Two- and four-choice assays were...
Planting depth within-field soil variability effects on corn stand establishment and yield
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Seedbed conditions during corn (Zea Mays L.) planting can have substantial impact on corn stand establishment and final yield. Optimal stand establishment is associated...
Soybean tolerance to off-target dicamba damage
(University of Missouri--Columbia, 2022)
Since the commercialization and widespread adoption of dicamba-tolerant (DT) soybean cultivars across the United States, numerous cases of off-target damage to non-DT soybean have been reported. Previous studies have focused ...
Horticultural crop response to synthetic auxins
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Rising adoption of dicamba-tolerant soybeans increases the potential exposure of grapes to dicamba, where off-target injury may occur via particle or vapor drift. In 2017...
