Extract

Once it has been determined that the primary mode of action of a herbicide is dependent upon entry into the plant through its roots, it becomes important to know what factors will influence its movement in the soil. The findings of Ennis (3, 4) and Baldwin, Freed, and Fang (1) that certain cereals absorb carbamates by means of their roots rather than through their leaves stimulated experiments to study the effects of various soil factors upon the persistence and movement of carbamates in the soil. Blouch and Fults (2) found that the effect of various soil types on the effectiveness of pre-emergence applications of CIPC to several crops was much less than the effect of soil structure and high levels of organic matter. Data presented by Ogle and Warren (9) indicated that organic matter may have considerable effect on inhibiting the movement of CIPC in the soil. They also emphasized that the herbicidal behavior of a chemical in soil cannot be predicted from a study of one soil type, since there appears to be an interaction between soil type and movement of the herbicide. Smith and Ennis (12) reported similar results and also found that oil solutions of CIPC were less mobile than aqueous solutions.
