Biology, Epidemiology, and Management of Spring Dead Spot of Bermudagrass
… predominantly O. korrae. In vitro and in situ fungicide efficacy screenings were conducted for O. herpotricha and O. korrae. Additionally, field studies were conducted to optimize fungicide applications and bermudagrass recovery from SDS. Results highlighted that, generally, O. korrae was less …

Host Range, Fungicide Resistance and Management of Pseudoperonospora cubensis, Causal Agent of Cucurbit Downy Mildew
… are no longer solely controlling downy mildew, fungicides are necessary to manage the disease. A fungicide efficacy trial in 2004 in Sampson County, North Carolina reported the reduced efficacy of mefenoxam and QoI fungicides, azoxystrobin and pyraclostrobin. To confirm resistance, the …

Effects of chitosan oligosaccharide-amended fungicide treatments on the control of fusarium head blight in wheat
… Current management strategies rely heavily on fungicide applications; however, their effectiveness varies among active ingredients, and overuse may lead to fungicide resistance and environmental concerns. Chitosan oligosaccharide (COS) is a product derived from chitin deacetylation that has …

Molecular techniques for studying <i>Fusarium</i> ear blight of wheat
… visual disease assessment were used to evaluate fungicide efficacy against FEB of wheat caused by <i>F. culmorum</i> and <i>F. poae</i> in three glasshouse trials (1994/5-1996/7). Prochloraz and tebuconazole significantly decreased both visual symptoms of FEB and fungal DNA content of <i>F. …

Optimising fungicide application tactics: using mathematical modelling to understand qualitative and quantitative fungicide resistance management
… fungal pathogens include chemical control with fungicides and use of disease-resistant cultivars. Both strategies are threatened by pathogen evolution leading to fungicide resistance and loss of cultivar efficacy (‘cultivar breakdown’). Both fungicide resistance and cultivar breakdown can be …

INTEGRATING FUNGICIDE RESISTANCE MONITORING AND FORECASTING MODELS FOR THE PRECISION MANAGEMENT OF GRAPEVINE DOWNY MILDEW
… still relies heavily on repeated applications of fungicides, which remain the most effective and widely adopted means of control. However, this high level of chemical input is associated with increasing concerns regarding environmental and human health impacts and has led to the progressive …

Evaluation of race population distribution, fungicide sensitivity, and fungicide control of Exserohilum turcicum, the causal agent of northern leaf blight of corn
… 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, propiconazole, and …
