%X This study was carried out for determine the problem weeds on daffodils and hyacinth in £¿zmir between 2013 and 2014. O. pes-caprae (94.74 %) was determined as highest frequency of occurrence in study. E. cicutarium (52.0 %), B. tectorum (50,0 %), H. murinum (44.74 %) and G.aparine (44.73 %) together with this weed were listed in the survey as the first five weeds. As sour grass is the weed type with the highest frequency of occurrence (O. pes-caprae) and as it is an invasive weed, it is estimated that it will spread more in the following years. O. pes-caprae (115.42 Weeds/m2) has been identified as the densest weed in terms of the weed density. H. murinum (34.38 Weeds/m2), A. sterilis (26.29 Weeds/m2), T. repens (14.29 Weeds/m2), B. tectorum (11.42 Weeds/m2), E. cicutarium (8.47 Weeds/m2) followed it respectively. Herbicides with 4 different active substances were taken under evaluation in 3 replications according to a randomized complete block experiment design. When the effects of herbicides on weed dry weights, the greatest effect was obtained from Oxyfluorfen herbicide (43.20 %). This effect was closely followed by Picloram + 2,4 D (43,18 %). Other effective applications were Aclonifen effect (38.10 %) and Phendimethalin (36.00 %) and Solarization (5.60%)
