Abstract Ornamental flowers are transplanted in the parks and house spaces These flowersare annual and seasonal and their planting is time consuming and their stablishment islow Thus they may be replaced in place of the previous flower after grown in thenursery The weeds in these fields could be controlled by avoiding seed germination andgrowth In this experiment the effect of some herbicides on weed control of warmseason flowers including Marigold Petunia Ageratum was evaluated In this study fivetreatment of control hand control and herbicides Treflan Dacthal and Gallant were inthe first experiment three times sampling and in the second experiment two timessampling were performed for measuring the presence of weeds weed dry matter pereach square meter height cover and persistence of the flower The results of the firstflower showed that weed control was differed among different treatment Hand controlsignificantly had the highest weed control and treflan was the most effective herbicide Weed eradication significantly increased flower height and hand control and treflanwere the effective treatment The interaction between herbicide treatment and time washighly significant Also the highest cover was observed in hand control and terflan Thehighest level of cover was achieved in the last time Among flowers only Petunia hadsignificant difference for flower persistence and terflan was the most effective treatmentin this regard It seems that overall on weed eradicated treflan treatment may besuggested for weed control But regarding flower treflan for Marigold dacthal forPetunia and dacthal and gallant for Ageratum could be suggested The results showedthat weed eradication may not show the better flower cover In the second experiment hand control and treflan were also the most effective for two plants Mean comparisonof flower with length and flower height in Mathiola showed that hand control andtreflan had not significant difference Mean comparisons of cover diameter and plantheight in viola showed that hand control and treflan were the better treatment Alsothese treatments were the most effective regarding flower persistence in Mathiola Butin Viola there was not significant difference between these two treatments Overal onweed eradicated treflan could be suggested for weed control of both two flowers
