In the first part of the are presented aspects regarding the control of weeds in wheat crops, among which Convolvulus arvensis L. is more prominent, a problem species popularly called bindweed (Ciocârlan et al., 2004; Fritea T.,2001). In the second part are described the materials and methods used to control problem weeds by which were evaluated the degree of control of the species Convolvulus arvensis L. in % and the wheat crops in q/ha on non-herbicide - treated variants and on those herbicide - treated. In the chapter called results and discussions are presented the results of the research regarding the total number of weeds/m 2 in the non-herbicide - treated variant in wheat crops and the occurrence percentage. In wheat crops 12 species of weeds were recorded, with a total number of 58 on m 2 and a occurrence percentage of 100%.  The bindweed was present in wheat crops in a number of 11.33 weeds/m 2 with an occurrence of 19.53%. The last part of the paper includes the conclusions, where one can notice that the most efficient bindweed sprouts reduction, in the year 2011, was obtained with the herbicide Dicamba 120 g/l + 344 g/l acid 2,4 D - 0,9 l/ha, with a control degree of 90,90%. A control of over 70% was registered also in the variants treated with Bomoxinil: 280 gr/l + acid 2,4 D - 1,0 l/ha and 300 g/l acid 2.4 - D +  100 g/l dicamba - 1 l/ha. All tested herbicides were highly selective for the variety of wheat cultivated (Lovrin 50), presenting no visible signs of phytotoxicity. The wheat crops obtained in the experimental field were influenced, on one hand by the climatic conditions, on the other hand, were positively correlated with the performances of herbicides in controlling total weed-growth and that with bindweed.
