- Abstract
Ambrosia artemisiifolia L. is considered to be one of the worst invasive alien species in Europe. Common ragweed invades a broad range of open disturbed areas (waste lands, roadsides, railway tracks, riverbanks) and causes considerable yield losses in field crops, such as in sunflower, maize and soybean. The species has highly allergenic pollen, which causes allergic rhinitis and asthma. In the last years, extensive common ragweed populations were observed in several European regions and the control of this species became very important from the point of economy and human health. The main purpose of control is the reduction of Ambrosia seeds in the soil seed bank to prevent their germination and further development With the purpose of investigating the suppressive role of lucerne (Medicago sativa L.), cocksfoot (Dactylis glomerata L.) and a mixture of them on the growth and development of Ambrosia artemisiifolia L., a study was conducted on a sandy clay loam soil. During the 2008-2009 period, a trial was carried out with the following variants: V1 Medicago sativa, V2 Dactylis glomerata; V3 M. sativa + D. glomerata; V4 Ambrosia artemisiifolia (control); V5 M. sativa + A. artemisiifolia; V6 D. glomerata + A. artemisiifolia; V7 M. sativa + D. glomerata + A. artemisiifolia. The results have shown that some perennial forage plants, e.g. M. sativa, D. glomerata and a mixture of M. sativa + D. glomerata are a reliable means to suppress the growth, development and seed production of A. artemisiifolia under suitable conditions. This approach is an ecological alternative for limiting the spreading of ragweed on arable land.
