This paper shows the efficacy of the control process of the species Convolvulus arvensis L., commonly called field bindweed, in maize, using a diversified range of post-emergent herbicides. Scientific research begins with the description of the general aspects of controlling weeds, in general, and the weed species Convulvulus arvensis L., in particular – a problem weed in crops, in general, and in maize, in particular. Within the trial, we tested 7 herbicides aiming at controlling weeds, in general, and the weed species Convulvulus arvensis L., in particular, in maize. As a result of our trials, we could point out the results concerning the total number of weeds/m 2 in the control (not treated) variant in maize, the efficacy of the tested herbicides in diminishing weeding degree, their selectivity to the cultivated maize hybrid cultivar, and maize yields in q/ha in both the control and treated variants. The authors identified, in maize, 11 species of weeds totalling 282 plants/m 2 , of which 24.2 plants/m 2 were represented by field bindweed that shared 8.58% of the total weeds in maize. As for the exclusive control of the species Convolvulus arvensis L., the best results were in the variant treated with Buctril Universal (0.8-1 l/ha), the control percentage reached 85.97%, while the highest maize yield was also in the variant treated with Buctril Universal (0.8-1 l/ha), i.e. 81.48 q/ha.
