This study has been conducted into the rangelands of Mediterranean climatic zone aim to control the commonly found Asphodelus aestivus Brot. weed plant having poisonous characteristics due to the presence of glycosides inside it. The research was carried out in Gerlengeç village of Biga District at Çanakkale Province, Turkey. Herbicide application was done in the month of April in 2015 while the tuber samples were collected in the month of April in 2016. The following five different herbicides were used in the control of A. aestivus due to the non-availability of any selective and specific herbicide that has being used in the chemical control of this weed species. In general; chlorosulfuron, dicamba+Triasulfuron and tribenuron methyl+thifensulfuron methyl herbicides affect the broad-leaved, metsulfuron methyl+lodosulfuron methyl is used in the control of narrowleaved, while glyphosate is an all-rounder herbicide that is used in the control of broad as well as narrow-leaved weed plants. In addition, two different doses (applied and double) of the above mentioned herbicides were selected to apply. The research was established according to the randomized complete block design (RCBD) by using three replications. The effects of applied herbicides have been investigated on tuber characteristics of A. aestivus in this research. As a result, the applied herbicides showed significant effects on the weight, length, diameter and the number of tuber while the applied doses were found with significantly important effects only on the weight and number of tuber. It concluded that the most effective herbicides were chlorosulfuron and glyphosate, and the best effective dose was observed as the ‘double dose’ in the chemical control of summer asphodel.
