Abstract :The content of water-dispersible phenol substances in rhizosphere both of annual and perennial species of weeds insert ignore into journalissuearticles values( Cirsium arvense, Sonchus arvensis ); increases under soil treatment minimalization. The higher content of phenol substances of researched weeds is defined in rhizosphere of Common Couch insert ignore into journalissuearticles values( Agropyrum repens );. The absence of intensive anthropogenic treatment of plowing layer which accumulates the significant mass of weed’s roots in the cause of much more higher allelopathic potential of some species’ of weeds. The high level of saturation by weeds in agrophytocoenosis under non-tillage soil treatment is defines the competitiveness between certain sepsis’ of weeds, especially, at the beginning of the vegetation. In this case, increasing the secretion of phenol substances is one of the physiological screenings of such competitiveness.
