Abstract:

In order to explore efficient, low toxic and eco-friendly fungicides, a series of 1,2,4-triazole and thiadiazole derivatives containing benzenesulfonamide moieties was designed and synthesized. Their chemical structures were confirmed by nuclear magnetic resonance spectroscopy(NMR), mass spectrometry and elemental analysis. Preliminary fungicidal bioassay in vitro was carried out against seven plant pathogenic fungi and the results showed that compounds 10 exhibited moderate fungicidal activities, especially 10a, 10g and 10n demonstrated similar high inhibition rate against Fusarium moniliforme in comparison with commercial Azoxystrobin.

Key words: triazole, thiadiazole, benzenesulfonamide, fungicidal activity
