title: Evaluation of the efficiency of 2.4-D, clopyralid and glyphosate in relation to Ambrosia artemisiifolia L. growing in Belarus
abstract: The biological effectiveness of the active substances 2.4-D, clopyralide and glyphosate (Sigma, USA) in relation to ragweed under the controlled laboratory conditions was studied. The number of physiological parameters (plant height, leaf formation, stem diameter, chlorophyll content, dry weight accumulation) of the studied plants were also evaluated. It was found that treating ragweed plants having 3 pairs of leaves by herbicides 2.4-D, clopyralid and glyphosate showed maximum biological effect
