Using a combination of herbicides has the potential to broaden the range of controlled weed species and prevent the development of herbicide resistance in weeds. Therefore, this study aimed to evaluate the effectiveness of a herbicide blend containing Atrazine (265 g/L) and Nicosulfuron (35 g/L) in managing weed in hybrid maize crops. The experiment was conducted at the Experimental Farm of the Faculty of Agriculture, Padjadjaran University, located in Jatinangor, Sumedang Regency, West Java, Indonesia. The experiment was laid out in Randomized Block Design comprising of seven treatments and four replications each. The treatments included different doses of Atrazine (265 g/L) and Nicosulfuron (35 g/L) at 1.0 l/ha, 1.5 l/ha, 2.0 l/ha, 2.5 l/ha, 3.0 l/ha, as well as manual weeding and control. The results showed that herbicide combination of Atrazine (265 g/L) and Nicosulfuron (35 g/L) at a dose of 1.0 L/ha to 3 L/ha was effective in controlling the growth of the dominant weed Bidens pilosa, Ageratum conyzoides, Synedrella nodiflora, Richardia brasiliensis, Eleusine indica, Digitaria ciliaris, and total weed on hybrid maize cultivation up to six weeks after treatment. During this observation period, there were no toxicity indications to maize plants, indicating the absence of phytotoxicity. Top Keywords Atrazine, Herbicide, Maize, Nicosulfuron, Toxicity, Weed.
