Study on Mechanisms of Resistance to SDHI Fungicide Pydiflumetofen in Fusarium fujikuroi.

Journal of Agricultural and Food Chemistry, 2023
Rice bakaenii disease (RBD) is a widespread and devastating disease mainly caused by Fusarium fujikuroi. Pydiflumetofen (Pyd) is a novel succinate dehydrogenase inhibitor (SDHI) with strong inhibitory activity against F.

Fusarium graminearumFgSdhC1 point mutation A78V confers resistance to the succinate dehydrogenase inhibitor pydiflumetofen

Pest Management Science, 2022
BACKGROUND Fusarium head blight (FHB) caused by Fusarium graminearum complex (Fg) is a devastating disease of cereal crops worldwide. The succinate dehydrogenase inhibitor (SDHI), pydiflumetofen, has been registered for management of FHB in China in 2019.

Comprehensive evaluation of chiral pydiflumetofen from the perspective of reducing environmental risks

Science of the Total Environment, 2022
The spatial structures of chiral pesticide enantiomers can affect their activity, toxicity and behavior, thereby altering exposure risk. Identifying enantiomer differences and developing high-efficiency green enantiopure pesticide is an important strategy for reducing the negative effects of pesticides.

Pydiflumetofen in paddy field environments: Its dissipation dynamics and dietary risk

Microchemical Journal, 2021
Abstract Pydiflumetofen is a broad-spectrum fungicide, the residues of which contaminate crops or are released into the environment, posing a threat to organisms and human health. In this study, pydiflumetofen residues in paddy field ecosystems were determined using quick, easy, cheap, rugged, safe (QuECHERS) sample preparation coupled to high ...

Evaluation of exploitive potential for higher bioactivity and lower residue risk enantiomer of chiral fungicide pydiflumetofen

Pest Management Science, 2021
AbstractBACKGROUNDPydiflumetofen, as a new succinate dehydrogenase inhibitor (SDHI) chiral fungicide, has been used in crop production because of its broad‐spectrum and high‐efficiency antifungal activity. However, little is known about pydiflumetofen at the chiral level.

Bioactivity, physiological characteristics and efficacy of the SDHI fungicide pydiflumetofen against Sclerotinia sclerotiorum

Pesticide Biochemistry and Physiology, 2019
Sclerotinia sclerotiorum, which can cause Sclerotinia stem rot, is a devastating plant pathogen. This study aimed to assess the potential of pydiflumetofen, a new-generation succinate dehydrogenase inhibitor (SDHI) fungicide, to control Sclerotinia stem rot.

Risk assessment and underlying mechanisms of pydiflumetofen resistance in Alternaria tenuissima and Alternaria alternata.

Pesticide Biochemistry and Physiology
Potato early blight is a prevalent disease that significantly impacts potato cultivation. Pydiflumetofen, a new succinate dehydrogenase inhibitor developed by Syngenta, has been registered for use on multiple crops in China. However, its resistance risk and mechanisms in Alternaria tenuissima and Alternaria alternata are still poorly understood.

Determination of Pydiflumetofen Residues in Rice and its Environment by an Optimized QuEChERS Method Coupled with HPLC-MS

Bulletin of Environmental Contamination and Toxicology, 2021
Pydiflumetofen is a new succinate dehydrogenase inhibitor fungicide, and the method for determination of its residues in rice and associated environmental samples has not yet been reported. Here, we optimized, Quick Easy, Cheap, Effective, Rugged, Safe (QuEChERS) method for sample preparation, and used high performance liquid chromatography-tandem mass
