A STUDY ON THE SELECTIVITY AND EFFICIENCY OF A GROUP OF HERBICIDES IN "DUNAVIYA" WHEAT VARIETY
In the experimental field of the Institute of Agriculture and Seed Science "Obraztsov Chiflik", Ruse, in 2017 - 2018, a study was conducted to determine the reaction of "Dunaviya" wheat variety, treated with herbicides for foliar fertilization at optimal and double doses - metasurfuron - methyl, fenoxaprop-P-ethyl, 2.4 amine salt. They did not have negative effects on the plants. Regarding destroyed weeds, all the three tested vegetation herbicides (metasurfuron - methyl, fenoxaprop-P-ethyl and 2.4 amine salt), applied at optimal and increased doses, showed high herbicidal efficiency against annual cereal and deciduous weeds. The use of metasurfuron - methyl, fenoxaprop-P-ethyl and 2.4 amine salt herbicides led to higher grain yield, compared to the untreated control.
