This research conducted in the plastic garden house private in Natar, <br />South Lampung and in the Weeds laboratory of Agriculture faculty, Lampung <br />University from June until July 2013. This Research arranged in a Randomized <br />Completely Design (RCD). Treatment consists of three types of herbicides with six <br />level of dosage active ingredient, namely of single herbicides is atrazin 500 g l<br />-1<br /> (0, <br />76, 152, 304, 608, and 1.215 ha g-1<br />), mesotrion 50 g l<br />-1<br /> (0, 11, 22, 43, 86, and 172 g <br />ha-1<br />), and mixed herbicides from atrazin 500 g l<br />-1<br /> + mesotrion 50 g l<br />-1<br /> (0, 28, 56, 112, <br />225, and 450 g ha-1<br />). The target weed were a type of broadleaves (Asystasia <br />gangetica), a type of grasses (Paspalum conjugatum), and a type of sedges (Cyperus <br />kyllingia).Homogenity tested using Bartlet and aditivity tested using Tukey, data <br />analyzed by Analisis of Variance and different median values tested with Least <br />Significant Difference (LSD) level 5%. Results showed that an active ingredient <br />mixture of atrazin 500 g L-1<br /> + mesotrion 50 g L-1<br /> has LD50 expectation value of 51,48 <br />g ha-1<br /> and LD50 treatment of 257,48 g ha-1<br /> with the co-toxicity value was 0.2 (co-<br />toxicity &lt; 1) until mixture was antagonist. <br /> <br />Keywords: Atrazin, mesotrion, herbicide mixture, Multiplicative Survival Model <br />( MSM), LD50</p>}, number={1}, journal={Jurnal Penelitian Pertanian Terapan}, author={Wati, Nana Ratna and J.
