Abstract

A series of tests was conducted under greenhouse conditions to determine the relative usefulness of various herbicides for control of weeds in cortisone yam (Dioscorea composita Hemsl.) plantings. Monuron, Diuron, Neburon, Atrazine, Simazine and Prometryne each were applied at three different rates. Diuron and Monuron were found to be the most toxic of the substituted ureas. The most injurious of the triazines was Atrazine. Simazine, although somewhat toxic, was less so than than Atrazine. No evidence of Prometryne poisoning could be detected. As expected, the number and weight of weeds were significantly lower in the test plots of plants treated with herbicides.
