Description
Summary:Environmental constraints of crop production systems have stimulated interest in alternative weed management strategies, as the continued use of synthetic herbicides has resulted in serious ecological problems, such as weeds resistance to important herbicides and increased environmental pollution and health hazards. The aim of this study was to test the bioherbicidal activity of the essential oil of Rosmarinus officinalis L. on weed species Senecio vulgaris L., in 2019, at the Faculty of Agriculture, University of Novi Sad. In order to examine a phytotoxic effect, plants were treated with 1 and 5% (v/v) concentration of rosemary essential oil, kitchen salt NaCl (1:8), wine vinegar solution (1:10), and glyphosate, while the control variants remained untreated. The evaluation was carried out 1, 24, 48, 72, 96, 120 and 144 hours after application. Essential oils of rosemary in both concentrations and wine vinegar solution (1:10) had good efficacy compared to the control. High efficacy was in the treatment with NaCl solution and glyphosate, and complete decay of S. vulgaris plants occurred 144h after application. Phytotoxic changes in the form of turgor loss, chlorotic, then necrotic spots, were determined on the tested weed species 24h from the application of NaCl and glyphosate, while from essential oil first symptoms have appeared after 48h.
