Extract

Certain members of the phenyl carbamate series and some salts of trichloroacetic acid have been known for several years to possess strong herbicidal properties, particularly toward monocotyledonous plants. This action has been described by Ivens and Blackman (4), McCall and Zahnley (5), Freed and Bierman (2), and others. Inconsistent results obtained in the usage of these chemicals have discouraged many workers from accepting them as useful weed control tools. Recently, Freed (3) analyzed several factors influencing the success or failure of IPC (isopropyl–n–phenyl carbamate). Among these are biochemical specificity, decomposition by soil microorganisms, moisture requirements, and stage of plant development. It has also been demonstrated by Anderson et al (1) that rapid evaporation of carbamates may be a critical factor at temperatures above 75 °F.
