FIELD: weed control agents. SUBSTANCE: method of controlling weeds within useful plant cultures resistant against phosphorus-containing herbicides is provided consisting in treatment of cultivated plants or their biotope with efficient amount of composition, which comprises, in addition to conventional inert auxiliary substances, (i) phosphorus-containing herbicide selected from gluphosinate and glyphosate, (ii) synergetically effective amount of at least one more herbicide selected from group including: prosulfurone, primisulfurone, dicamba, pyridate, dimethenamide and its S-enantiomer, metholachlore and its S- enantiomer, propaquizaphope, atrazine, clodinaphope, terbutylazine; and also (iii) compound of formula: 
on condition that (i) compositions containing glyphosate and metholachlore, glyphosate, metholachlore, and atrazine as well as gluphosinate, atrazine, and dicamba are not applied on maize resistant against gluphosinate and (ii) compositions containing glyphosate and atrazine are not applied on maize resistant against glyphosate, and (iii) compositions containing glyphosate and metholachlore or glyphosate and dimethenamide are not applied on soybean resistant against glyphosate. Herbicide compositions used in weed control method are also described. EFFECT: ensured suppression of most weeds mainly occurring within useful plant cultures resistant against gluphosinate or glyphosate without significant damage of useful plants themselves. 10 cl, 5 tbl, 5 ex
