The objective of this research was to know the efficacy of atrazine herbicide to control the common weed in maize (Zea mays L.) field and how was the phytotoxicity to maize (Zea mays L.) plant.

The experiment was arranged in Completely Randomized Block Design (CRBD) with six treatments and four replications. The treatments are atrazine herbicide at 1.2, 1.6, 2.0, and 2.4 kg ha-1, mechanic weeding, and control. Homogeneity of variance was tested by Bartlett test and additivitty tested by Tukey's test, the comparison of mean were tested by Least Significant Difference (LSD) test at 5% level. The result showed that (1). Atrazine herbicide at 1.2 – 2.4 kg ha-1 could suppress total weed until 6 Week After Treatment (WAT).
