Cercospora sojina: over-winter survival and fungicide resistance
… 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 fungicide resistance …

Fungicide Sensitivity of Erysiphe necator and Plasmopara viticola from Virginia and nearby states
… leaf disc bioassays, 92% of the DM isolates were QoI (azoxystrobin)-resistant, but none were resistant to mefenoxam. Eighty-two percent of the PM isolates were QoI-resistant, but none were resistant to boscalid and quinoxyfen. The frequency of the G143A point mutation, which confers high levels of …

Model adaptivity for goal-oriented inference
… may be a low-dimensional Quantity of Interest (QoI); we refer to this as the goal-oriented inverse problem. We present a novel algorithm for solving the goal-oriented inverse problem, which allows one to manage the fidelity of modeling choices while solving the inverse problem. We formulate a …

Characterizing resistance of Erysiphe necator to fungicides belonging to the quinone outside inhibitors and demethylation inhibitors
… Erysiphe necator to quinone outside inhibitors (QoIs) is now widespread, and resistance to demethylation inhibitors (DMIs) has also developed. The goal of this research was to characterize fungicide resistance by elucidating resistance mechanisms and determining its stability. QoI resistance …

A combinatorial approach to goal-oriented optimal Bayesian experimental design
… setting. Here, the quantity of interest (QoI) is not the model parameters, but some (vector-valued) function of the parameters. We wish to select a subset of the candidate observations that is most informative for this QoI, in the sense of reducing its uncertainty. More precisely, we seek …

Modeling and Scheduling for Sensor Network Quality-of-Experience Enhancement
… to consistently provide quality of information (QoI) while being functional for an expected lifetime. Thus, the two quantities characterizing QoE are: QoI and network lifetime. Quality of information, as the name suggests, defines the quality of the information received by an application, which …

Scalable online nonlinear goal-oriented inference with physics-informed maps
… some low-dimensional quantity of interest (QoI). When computational resources and/or time are limited, it is infeasible to solve the full inverse problem for inferred parameters to obtain the QoI.

Genotypic characterization and fungicide resistance monitoring for Virginia populations of Parastagonospora nodorum in wheat
… 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 diversity of P. nodorum …

Characterization of Fungicide Resistance in Venturia inaequalis Populations in Virginia
… the sterol-inhibiting (SI) and strobilurin (QoI) fungicides are the most commonly used. Recent observations indicate that V. inaequalis populations in Virginia have developed resistance to myclobutanil and other SIs. However, little is known about the frequency and distribution of SI and QoI …

Effective Formulations of Optimization Under Uncertainty for Aerospace Design
… statistical moments of the quantity of interest (QOI) as separate objectives—can result in stochastically dominated designs. A stochastically dominated design is undesirable, because it is less likely than another design to achieve a QOI at least as good as a given value, for any given value. As a …

On quantifying the quality of information in social sensing
… for quantifying the Quality of Information (QoI) in social sensing. We refer social sensing to the sensing applications where humans play a critical role in the sensing or data collection process. Social sensing has emerged as a new paradigm for sensory data collection, which is motivated by …

Quantification of Fungicide Resistance in Cercospora sojina Populations and Development of a Fungicide Application Decision Aid for Soybean in the Mid-Atlantic U.S.
… 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 for disease development, …

Evaluation of race population distribution, fungicide sensitivity, and fungicide control of Exserohilum turcicum, the causal agent of northern leaf blight of corn
… Fungicides containing quinone outside inhibitor (QoI) and demethylation inhibitor (DMI) active ingredients alone or in combination are frequently applied to control NLB. Field trials were conducted in Illinois at DeKalb, Monmouth, and Urbana in 2012 and Dixon Springs and Urbana in 2013 to evaluate …

Identification of fungal species causing powdery mildew on cucurbits, determination of the genetic and pathogenic variations of the fungi and their sensitivity to major powdery mildew fungicides
… used powdery mildew fungicides, including DMI, QoI, SDHI, quinolines, and cyflufenamid fungicides. To identify the species of powdery mildew fungi, powdery mildew infected leaves of C. melo, C. sativus, C. maxima, C. moschata, C. pepo, and L. siceraria were collected from California, Illinois, …

Alternaria Leaf Blight and Head Rot of Broccoli: UAV-Based Disease Detection and Fungicide Resistance Management
… 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 disease-tolerant broccoli …

Trust-aware virtual network embedding algorithms for wireless sensor networks
… while considering the quality of information (QoI), quality of service (QoS), and wireless interference handling constraints. Improving the acceptance rate of VNE is essential because the more the virtual network requests (VNRs) can be mapped onto the substrate network, the more revenue they …

Evaluating Fungicide Timing for Leaf Spot Diseases of Wheat and Fungicide Resistance in Pyrenophora tritici-repentis
… fungicides such as quinone outside inhibititors (QoI) like pyraclostrobin or demethylation inhibitors (DMI) like propiconazole. It is therefore imperative to limit the amount of fungicide applied to fields to reduce the exposure to pathogens that may lead to insensitivity. The objective of this …

Resource efficient information integration in cyber-physical systems
… the tradeoff between the quality of information (QoI) provided by the sensor nodes and the consumption of system resources. On one hand, individual sensors are not reliable, due to various possible reasons including incomplete observations, environment and circuit board noise, poor sensor quality, …

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 …
