Abstract

Experiments were performed from 2021 to 2022 in Ardabil, Alborz, and Kermanshah province, Iran, to evaluate the efficiency of Terbuthylazine and Isoxaflutel + Thiencarbazone on controlling weeds in corn feilds. Examined herbicides included Terbuthylazine (A-Maize-ing 50% SC), Isoxaflutel + Thiencarbazone (Adango SC 46.5%), Mesotrione + S-metolachlor (Lumax 53.75% SE), 2. 4, D + MCPA (67.5% SL), Bromoxynil + MCPA (Bromicide MA 40% EC), Bromoxynil + MCPA (Bromicide MA 40% EC) + Nicosulfuron (Cruze 4% SC). The results showed that application of A-Maize-ing, Adengo, Lumax, 2. 4, D + MCPA, Bromicide MA, and Bromicide MA + Cruze herbicides affected weed density and dry weight (more than 85%), increasing the corn yield in all three provinces. A-Maize-ing and Adengo were as effective as other commonly used herbicides in corn fields of Iran; therefore, the use of these herbicides can be recommended. Redroot pigweed and common lambsquarters weed plants were sensitive to A-Maize-ing and Adengo herbicides.
