Özet: Within the period 2011-2014 in the experimental field of the Agricultural University, Plovdiv, were conducted field experiments using the herbicides Teridox (500 g/1 dimetochor), Butizan S (500 g/1 metazachlor), which were applied to the soil after planting the crops and before their germination, and also Modaon 4F (48 g/1 bifenox) and Butizan S, which was applied to the leaves during the vegetation period of the rape. The experiments were made using the block method over an area of 25 m2 in three repetitions. It has been established that the herbicides demonstrate excellent selectivity for this crop, and have excellent control: Amaranthus retroflexus L., Portulaca oleraceae L., Chenopodium album L., Solanum nigrum L., Setaria spp., Stellaria media L. and self seeded wheat plants. Herbicides dimethachlor, bifenox and metazachlor not have a negative impact on growth and phenological development of rapeseed hybrid Xenon. In the three years experienced plant height in the treated variants statistically proven to exceed zero control. Depending on weather conditions the vegetation period of plants occurs for 263 days (in 2012/2013) to 279 days (2011/2012)
