摘要：

Twenty-five novel sulfonylureas containing thiadiazole have been synthesized by treating 2-amino-5-subthiadiazole with sulfonylisocynate. Their structures were confirmed by IR, H-1 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.
