Study on the enantioselective behaviors, activity, toxicity and mechanism of novel SDHI fungicide benzovindiflupyr to reduce the environmental risks.

Benzovindiflupyr (BEN) has emerged as one of the fastest-growing SDHI fungicides in recent years, but it is considered "very highly toxic" to aquatic fish, invertebrates and crustaceans (EC or LC, 0.0035-0.056 mg/L, acute toxicity).

Comprehensive evaluation of chiral sedaxane with four stereoisomers for risk reduction: Bioactivity, toxicity, and stereoselective dissipation in crop planting systems.

A comprehensive evaluation of chiral pesticide at the stereoisomeric level is an effective strategy to improve efficiency and reduce risk on foods. For chiral sedaxane with four stereoisomers, there were 517-1013 fold differences in bioactivity for three kinds of phytopathogens and 3.73 fold differences in toxicity against model organism (Danio rerio) between the best (trans-1R2S-sedaxane) and worst stereoisomer (cis-1S2S-sedaxane).

First report of Fusarium solani causing Fusarium wilt of Bletilla striata (hyacinth orchid) in Zhejiang province of China.

Bletilla striata, a member of the family Orchidaceae, is a perennial herbaceous plant used in Chinese medicine. It is a commonly cultivated economic crop in the Yangtze River Basin provinces of China, as its roots are used to treat bleeding and inflammation. In Zhejiang province, Bletilla striata has a planting area of 1400 hectares with a total production of approximately 2.

First report of Colletotrichum scovillei causing anthracnose fruit rot on Eriobotrya japonicain in Zhejiang province, China.

Loquat (Eriobotrya japonica (Thunb.) Lindl.) is a fruit tree of high economic impotance in China.

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

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. In this study, after confirming the absolute configuration of pydiflumetofen enantiomers, fungicidal activity evaluation indicated that the activity of S-(+)-pydiflumetofen was 81.

First Report of Aureobasidium pullulans var. pullulans Causing Spot Blight of Pear (Pyrus pyrifolia) in Zhejiang Province of China.

Asian pear (Pyrus pyrifolia Nakai cv. cuiguan), is widely grown in Zhejiang province of China. In April 2019, symptoms consisting of small black, round leaf spots and blight flower petals were observed on over 30 % of 'Cuiguan' pear trees in an orchard (ca.

Enantioselective toxicity and mechanism of chiral fungicide penflufen based on experiments and computational chemistry.

Penflufen fungicide is widely used as a racemate, which has potential ecological risks to aquatic organisms, while its enantioselective toxicity data is limited. This study aimed to differentiate the enantioselective toxicity difference of penflufen enantiomers, and illuminate the enantioselective mechanism from the insight of enantiomer-protein specific binding. The semipreparative separation and absolute configuration of penflufen enantiomers were conducted.
