Abstract Delayed sowing of winter cereals or unfavorable weather conditions in autumn may make it impossible to carry out herbicide treatment autumn. In such cases, weed control should be started the spring. During this time, plantation protected as effectively possible because weeds are at an advanced stage growth. Therefore, they less sensitive applied herbicides. treatment, is worth using a mixture different mechanisms action. Studies were conducted evaluate effectiveness band...
