| Abstract:
The effect of a herbicide and two plant densities on the yield and quality of thyme (Thymus vulgaris L.), horehound (Marrubium vulgare) and dandelion (Taraxacum officinale), was measured. Ethalfluralin (EDGE®) was applied at 1.1 kg a.i./ha and incorporated to the soil prior to planting. Visual evaluations of weed and crop phytotoxicity as well as weed density determinations were made during the growing season. The three crop species were tolerant to ethalfluralin and weed control was satisfactory. Dry matter yields of thyme, horehound and dandelion in herbicide treated plots were on average 626, 2148 and 1404 kg/ha, respectively. No herbicide residues were found in harvested thyme and horehound shoots and dandelion roots. It is suggested that horehound and dandelion grown with ethalfluralin would benefit from a high density planting. | |
