Abstract

NEW MATERIAL:Carbamic acid ester derivatives of formula I (A is halogen-substituted pyridyl; R1 and R2 are H, lower alkyl, or (halogen-substituted phenyl).
EXAMPLE: 3-(3,5-Dichloropyridyl-2-oxy)phenyl N,N-dimethylcarbamate.
USE: Herbicides effective to almost all weeds by the stalk and leaf treatment in direct planting in a dry rice field and culture of rice grown in a dry field, and completely harmless to rice plant genus of true grasses. Strongly inhibit cell division growth of the growing point of weeds of true grasses except for rice plant. Act in the sunlight.
PROCESS: For example, the compounds of formula I wherein R1=H are obtained by the reaction of 3-(pyridyloxy)phenol of formula II and isocyanates of formula III (R2 is lower alkyl, or halogen-substituted phenyl).
