Genetic Differentiation in the SdhC Subunit Confers Intrinsic Resistance to SDHI Fungicides in Fusarium asiaticum. [PDF]
In Fusarium asiaticum, two homologous SdhC subunits (FaSdhC1/C2) regulate sensitivity to SDHI fungicides: deletion of FaSDHC1 decreases sensitivity, while deletion of FaSDHC2 increases it. Multiple mutations in ΔFaSDHC2 confer resistance to SDHI fungicides.

Molecular Mechanism Underlying Resistance Variation to the Novel Agrochemical Quinofumelin in Fusarium graminearum. [PDF]
The D155T, V179E, V179D and N281A mutations in FgDHODHII altered the binding mode of quinofumelin, resulting in diminished affinity and a negative correlation between binding affinity and the resistance level of these mutants. ABSTRACT Quinofumelin, a quinoline‐based fungicide, demonstrated potent antifungal activity against Fusarium graminearum, the ...

Sensitivity to demethylation-inhibiting fungicides and induced expression of CYP51 associated with tebuconazole resistance in Alternaria species on mandarin in Brazil. [PDF]
Tebuconazole‐resistant isolates overexpress CYP51 and, when tested at field rates, did not reduce ABS severity, whereas difenoconazole and mefentrifluconazole remained effective. Abstract BACKGROUND Alternaria brown spot (ABS), caused by Alternaria spp., is an important disease affecting mandarin production in several citrus‐growing regions worldwide ...

Effect of Field-applied Fungicides on Claviceps purpurea Sclerotia and Associated Toxins in Wheat
Claviceps purpurea (Fr.) Tul is the causal organism for ergot impacting grass hosts, including wheat. The pathogen produces ergot alkaloids (EAs) during the development of mature sclerotia leading to potential wheat quality discounts or rejection at the ...

Sensitivity of Fusarium asiaticum to a novel succinate dehydrogenase inhibitor fungicide pydiflumetofen [PDF]
Abstract Fusarium head blight (FHB) or scab mainly caused by Fusarium asiaticum is a devastating fungal disease in wheat. In China, carbendazim (MBC) and its co-formulated mixture with other fungicides are the main fungicides for controlling the disease. But resistant populations have developed severely in the field.

Pharmacological Characteristics and Control Efficacy of a Novel SDHI Fungicide Pydiflumetofen Against Sclerotinia sclerotiorum [PDF]
Pydiflumetofen is a novel succinate dehydrogenase inhibitor fungicide. In the current research, we determined the sensitivity of 166 Sclerotinia sclerotiorum strains to pydiflumetofen using mycelial growth inhibition method. The results suggest that pydiflumetofen exhibited a strong inhibitory activity against S.

ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers
