Summer asphodel is widely found in Mediterranean Rangelands. For being poisonous, it also causes a negative impact on rangelands quality. Therefore, a study has been carried out in order to prevent the growth of this weed plant depending on the application of different herbicides at different seasons. The research was conducted in the Gerlengeç village of Biga District at Çanakkale Province in 2016. Since there is no selective and specific herbicide in the chemical control with this weed plant that is why this study was conducted by using the active ingredients of five different herbicides in order to determine the most appropriate herbicide and its application season. Those of chlorosulfuron, dicamba+triasulfuron and tribenuron methyl+thifensulfuron methyl herbicides are effective against broad leaves while metsulfuron methyl+lodosulfuron methyl is used for narrow leaves and glyphosate is used for all types of herbaceous weed plants as a total herbicide. In addition, the herbicides were applied in two different seasons i.e., spring (March 2015) and autumn (November 2015). The research was established according to the randomized complete block design using three replications. The total experimental area was 100 m2 and each plot consisted of 3 m2 of the area in the experiment. The growth of Asphodelus aestivus has been observed after the application of above mentioned herbicides during the experiment. According to overall results of this research, the applied herbicides and their application seasons have been statistically significant on the investigated characteristics (number of plants, plant height, number of leaves, leaf diameter and length) of this weed plant. Consequently, the significant achievements were obtained from the plant in terms of herbicides and their application seasons.
