Influence of Treatment with Post-Emergence Herbicides on Productivity of Barley Emon, Lardeya and Orfey

Field trial with two-row barley varieties Emon, Lardeya and Orfej is conducted in the Institute of Agriculture – Karnobat during the period 2011-2013. The influence of broadleaf (dicotyledonous) herbicides alone and on their combination with wild oat (monocotyledonous) herbicides, applied in tillering stage of the crop in optimal and double doses, is investigated. The treatment with various herbicides and herbicide combinations had an effect on the yield of the studied barley varieties. In case of broadleaf weed infestation in the Lardeya crops they can be treated with almost any studied herbicide and they do not have a negative effect on the variety productivity. In the Orfey and Emon crops the broadleaf weed infestation is best treated with Sekator OD and Granstar Super. In case of mixed weed infestation in the three varieties, it is best to treat the crops with the combination Puma Super 7.5 EW + Sekator OD. The Lardeya and Orfej varieties appeared more resistant to all studied herbicide preparations, and the Emon variety was more susceptible
