The experimental data of 26 trials show that when winter grain crops are prevalently infested by weed plants sensitive to phenoxy acids (Chenopodium album, Сapsella bursa-pastoris, Thlaspi arvense, wind-fallen Brassica and etc.), 2,4D herbicidal activity is manifested at sufficiently high level – 90–100%. When in winter grain crop agrocoenosis the resistant to this herbicidal group weeds present (Galeopsis tetrahit, Stellaria media, Viola arvensis, Galium aparine, Sonchus arvensis,Cirsium arvense, Tripleurospermum inodorum) the efficiency of the given herbicides is decreased up to 10–50%. Regarding not very high cost (10–15 $ USD/ha) of cultivation the use of pure herbicides of this group on the fields infested with windfall (Brassica, Chenopodium album, Сapsella bursa-pastoris, Thlaspi arvense, Papaver rhoeas) is economically justified. Also these herbicides mixed with other groups can be used on the fields with a high level of infestation.
