Observations on biodiversity flora and biological control agents of natural grassland weed.
The flora of 2 natural pastures (one in Miroslava, which was under cattle grazing, and one in Perieni, which was grazed by sheep) in Romania that were invaded by Lepidium draba was studied in 2008. A total of 117 species of vascular plants belonging to 84 genera and 24 families were recorded. The plants consisted of forage species (such as Poa pratensis, Agrostis stolonifera, Dactylis glomerata, Festuca pratensis, Lolium perenne, Lotus corniculatus, Trifolium repens and Trifolium pratense), weeds (including Cirsium arvense, Cirsium vulgare, Convolvulus arvensis, Erigeron annuus, Onopordum acanthium, Eryngium campestre and Torilis arvensis), non-economically important forage species (Artemisia austriaca, Carex paper, Cichorium intybus, Rumex obtusifolius, Urtica dioica and Bupleurum tenuissimum) and toxic species (such as Euphorbia niccaensis and Ranunculus sardous). The potential biological control agents of Lepidium draba that were identified in the areas were Ceutorhynchus cardariae, Psylliodes wrasei and Aceria drabae.
