Sažetak
During 2005 and 2006. year on a good sample of the Institute for Lowland Forestry and Environment investigated the efficiency and selectivity of herbicide combinations acetoklor + flurokloridon, acetoklor + metribuzin and acetoklor + prometrin in production of poplar seedlings. Tests are set at two systematic unit of soils, with different physico-chemical properties. Investigated soils have different the reaction of soils, the content of CaCO3, P2O5and organic matter (Table 2).
The different physical and chemical characteristics of soils influenced the composition of different weed vegetation (Table 3), and the conduct and operation of the tested herbicides. At both study sites were the dominant broadleaf species while grass were represented to a lesser extent.
All investigated combinations of herbicides reduced the number of weeds in the investigated sites. Best efficiency in weed control on both studied surfaces is achieved by applying combinations of herbicide acetoklor + prometrin. Flurokloridon herbicide on both studied surfaces caused a transient damages on poplars seedling. Herbicide metribuzin is fitotoxic function manifested on the soil with a greater involvement of the total sand and its application to land lighter texture not recommended.
