The incidence and density of some weed species in or chards including plum, apricot and peach, is affected by numerous ecological factors: soil type and properties, configuration of the terrain, climatic conditions, plant/geographic relationships, geographic position of the or chard and level of human factors influenced by fruit cultivation measures, agricultural practices, physical and chemical measures undertaken when establishing and exploiting the orchard. In newly established or chards with intensive production, row weed species were noted to predominate. With years the weed species in the row region were segetal-ruderal species whereas inter row weed species predominated in the inter row place (where dominant segetal-ruderal species). In orchards focused on extensive production, the weed species registered were those found in pastures. The measures used to control or chard weeds may be mechanical, taking care of the land area (idle land, heath, cover crop growing) or chemical, i.e. using herbicides, an efficient and cheap way of solving the problem and protecting both or chard and the environment. There are only four active ingredients registered for pre-em application in our country compared with the world (16 pre-em a.i.). Only seven a.i. of the 14 known, have been registered for post-em application. In newly established or chards only one a.i. has been registered of the six known.
