Understanding variability associated with corn grain yield response to foliar fungicide application
Quinone outside inhibitor (QoI) fungicide (e.g., pyraclostrobin, azoxystrobin, and trifloxystrobin) fungicide application is becoming a common practice in corn production systems. The strobilurin class of fungicides inhibits mitochondrial respiration in fungal cells, and preventing plant pathogen …

Alternaria Leaf Blight and Head Rot of Broccoli: UAV-Based Disease Detection and Fungicide Resistance Management
… industry. Management traditionally relies on quinone outside inhibitor (QoI) fungicides, but recent reports indicate reduced efficacy. The causes for this decline are unclear, whether due to a novel species or resistance within existing species. Additionally, knowledge gaps exist regarding …

Genotypic characterization and fungicide resistance monitoring for Virginia populations of Parastagonospora nodorum in wheat
… research was to 1) determine the occurrence of quinone outside inhibitor (QoI) resistance in Virginia populations of P. nodorum infecting wheat, 2) quantify the distribution of G143A mutations conferring fungicide resistance in Virginia populations of P. nodorum, and 3) characterize genetic …

Quantification of Fungicide Resistance in Cercospora sojina Populations and Development of a Fungicide Application Decision Aid for Soybean in the Mid-Atlantic U.S.
… host resistance, foliar fungicides, often with quinone outside inhibitor (QoI) active ingredients, are used to manage these soybean foliar diseases. Yield benefits of foliar fungicides have been inconsistent and this may be the result of low disease pressure, unfavorable environmental conditions …

Fusarium in winter wheat: mycotoxin accumulation in straw and a survey of roots
… studies determined that: i) the demethylation inhibitor (DMI) fungicides did not provide significant control of mycotoxin accumulation in the straw over non-treated control plots, but significantly decreased mycotoxin accumulation over the application of quinone outside inhibitor (QoI) …

Management of stem rot of peanut using optical sensors, machine learning, and fungicides
… a direct application. Succinate dehydrogenase inhibitors provided less basipetal protection of stem tissues than quinone outside inhibitor or demethylation inhibitor fungicides. Overall, results of this research provide a foundation for developing sensor/drone-based methods that use …

Cercospora sojina: over-winter survival and fungicide resistance
… in this dissertation was the monitoring of Quinone outside inhibitor (QoI) fungicide resistance in C. sojina. QoI fungicides have been effective in managing frogeye leaf spot, but the risk of selecting C. sojina strains with resistance to this class of fungicides is considered high. A QoI …

Evaluation of race population distribution, fungicide sensitivity, and fungicide control of Exserohilum turcicum, the causal agent of northern leaf blight of corn
… to increase NLB control. Demethylation inhibitor (DMI) fungicides have been labeled for corn use since the early 1990s; in this dissertation a study was conducted to measure E. turcicum baseline sensitivity to DMI fungicides and monitor shifts in sensitivity over years. Metconazole, …
