Their structures were confirmed by IR, 1H NMR, 13C NMR and high-resolution mass spectroscopy. The preliminary bioassay results indicated that some title compounds had good fungicide activity at 50 ug/mL; most of the compounds presented a certain degree of direct inhibition activity, good inactivation and curative activity against tobacco mosaic virus at 500 ug/mL and 100 ug/mL; some compounds showed good larvicidal activity against Plutella xylostella L. at 200 ug/mL and excellent larvicidal activities against Culex pipiens pallens at 2 ug/mL.展开更多
