Weeds are among the most important factors that decrease crop yields in addition to climate and a variety used. Herbicide resistant varieties of different crops have made weed management easier in the recent era; therefore deteriming natural resistance in the available germplasm is of significant importance. This study was aimed at determining natural resistance of different lentil varieties, i.e., ‘Fırat 87’, ‘Çağıl’, and ‘Altıntoprak’ to imazamox herbicide. Six different imazamox doses, i.e., no application and ¼, ½, 1, 2, and 4-fold of the recommended dose were used in the experiment. The herbicide was applied at 4-6 leaves of plants. Plant samples were collected 28 days after herbicide application by harvesting the above-ground parts. The fresh and dry weight of the collected samples were recorded. The collected data were analyzed with SAS statistical software. Analysis of variance was used to infer the differences among tested varieties and log-logistic regression was used to determine the dose affecting half of the population (I50) and creating dose-response curve. The results revealed that ‘Fırat 87’ variety was the most tolerant to imazamox, whereas ‘Çağıl’ was the most sensitive. The I50 values for ‘Çağıl’, ‘Altıntoprak’ ‘Fırat 87’ were 14.05, 23.00 and 38.47 ml/ha, respectively. If it is considered the recommended dose of imazamox 100ml/da, much lower dose of imazamox is quite affective on these lentil varieties.
