During 2005-2006, at the Fruit Growing Institute - Plovdiv (Bulgaria) a study was carried out on the efficiency and selectivity of the soil herbicide dichlobenil - Casoron 6.7G in young sweet cherry plantations. A field experiment was conducted in a young orchard of Lapins cultivar grafted on the vegetative rootstock Gasela 5. The plantation was established 2001 on alluvial-meadow soil (fluvisol) at a planting distance of 5x3 m. The soil herbicide dichlobenil was applied during the fourth and the fifth growing seasons of the orchard, early in spring, before the beginning of weed plant development. The soil herbicide dichlobenil (trade mark Casoron 6.7G) applied at rates of 80.0-100.0 kg/ha had a very good herbicidal effect on a large number of annual and perennial grass and broad-leaved weed species. The efficient herbicide post-effect continued for about 7 months, controlling weed infestation during the whole vegetation period. Visiable symptoms of phytotoxicity and suppression of tree growth and fruiting were not observed after treatment with Casoron 6.7G applied at all the three applied rates.
