Compounds of the formula
wherein
R1 is CH3NH, CH3O, or CH3;
R2 CH3 or
R3 is H or CH3NH C-provided that when R2 is HC≡C, R1 is CH3NH and R3 is H; and provided that when R3 is
R1 is CH3NH and R2 is CH3; can be used to control fungus diseases of living plants, for which purpose they can be formulated into fungicidal compositions in conventional manner.
The compounds can be made by reacting e.g. 3-(1,1-dimethylethylamino) or 3-(1,1-dimethylallylamino) -1,1,1-trichloro-2-propanol with methylisocyanate, methyl chloroformate or acetic anhydride.
式中的化合物
式中
R1 是 NH、
CH3O 或
CH3;
R2 或
R3 是 H 或 NH C--前提是当 R2 是 HC≡C 时,R1 是 NH,R3 是 H;以及当 R3 是 NH 时,R1 是 NH,R2 是 。
R1为 NH,R2为 ;可用于防治活体植物的真菌病害,为此可按常规方法将它们配制成杀菌组合物。
