Fungicides which are sulfonamide derivatives are represented by the general formula;
wherein R' is lower alkyl, lower alkenyl, lower alkynyl or aryl of 6 to 10 carbon atoms optionally substituted by up to 3 halogen atoms; R2 is lower alkyl, lower alkenyl, lower alkynyl or aryl of 6 to 10 carbon atoms optionally substituted by up to 3 halogen atoms or up to 3 lower alkoxy groups; and R3 is alkyl of 1 to 3 carbon atoms substituted by 3 to 6 halogen atoms or trihalovinyl. The compounds are solids which unexpectedly have higher melting points and reduced solubilities which enhance their utility as fungicides.
属于磺酰胺衍生物的杀菌剂由通式表示;
其中 R'是 6 至 10 个碳原子的低级烷基、低级烯基、低级炔基或芳基,可选择被最多 3 个卤素原子取代;R2 是 6 至 10 个碳原子的低级烷基、低级烯基、低级炔基或芳基,可选择被最多 3 个卤素原子或最多 3 个低级烷氧基取代;R3 是 1 至 3 个碳原子的烷基,被 3 至 6 个卤素原子或三卤乙烯基取代。这些化合物是固体,意外地具有较高的熔点和较低的溶解度,从而提高了它们作为杀真菌剂的效用。
