Implication

Comparative study reveals distinct bioactivity, toxicity, and degradation across difenoconazole stereoisomers, suggesting pure (2R,4S) enantiomer reduces ecotoxicity.

Key Points

To comprehensively evaluate the stereoselective bioactivity, aquatic ecotoxicity, and environmental degradation behavior of difenoconazole stereoisomers in crops and soil.
Evaluated bioactivity of difenoconazole stereoisomers against fungal pathogens (Alternaria sonali, Fulvia fulva, Botrytis cinerea, and Rhizoctonia solani) and toxicity in aquatic organisms (Scenedesmus obliquus, Daphnia magna, and Danio rerio).
Investigated stereoselective degradation in cucumber (Cucumis sativus) and tomato (Lycopersicon esculentum) under field conditions.
Measured degradation dynamics and configurational stability in soil under controlled aerobic and anaerobic laboratory conditions.
Stereoisomers demonstrated a 1.33- to 24.2-fold difference in antifungal bioactivity and a 1.04- to 6.78-fold difference in aquatic ecotoxicity.
The (2S,4S)-stereoisomer exhibited the lowest antifungal bioactivity and highest aquatic toxicity, while showing variable enrichment between cucumber and tomato crops.
Soil degradation preferentially degraded (2R,4R)- and (2R,4S)-stereoisomers across aerobic and anaerobic conditions without configurational inversion.
