【Abstract】 Twenty-five novel sulfonylureas containing thiadiazole have been synthesized by treating 2-amino-5-subthiadiazole with sulfonylisocynate.Tlieir structures were confirmed by IR,1H NMR and elementary analysis.The preliminary biological test shows that compounds 1,2,5 and 22 are effective against broadleaf plants at 2.25 kg/ha in pre-or post-emergence;10,22,25 also exhibit certain fungicidal activity against puccinia Recondita at 0.125%in vivo.更多还原
