Compounds are prepared which correspond to the formula ##STR1## wherein X and Y represent OR', trichloromethyl, trifluoromethyl, dichloromethyl, dichlorofluoromethyl or chlorodifluoromethyl with the proviso that one of X or Y must be OR' and the other of X and Y is other than OR'; and R and R' each independently represent alkyl of 1 to 12 carbons or alkenyl of 3 or 4 carbon atoms. These compounds and compositions containing them have been found to be useful as agronomic fungicides, especially useful and valuable for the control of soil-borne plant disease organisms which attack the roots of plants.
制备了符合以下式子##STR1##的化合物,其中X和Y分别表示OR'、三
氯甲基、三
氟甲基、二
氯甲基、二
氯氟甲基或
氯二
氟甲基,但其中一个必须是OR',另一个不是OR';R和R'各自独立地表示1到12个碳原子的烷基或3或4个碳原子的烯基。发现这些化合物和含有它们的组合物在农学上是有用的杀菌剂,特别是用于控制攻击植物根部的土传植物病原体。
