The efficacy and selectivity of the contact herbicide oxyfluorfen (Goal 4F – 250 ml/da) having a soil and foliar activity, was studied in the period 2008 – 2010 at the Fruit Growing Institute – Plovdiv in a soil type Arenic Fluvisols by applying through the micro- irrigation system. The effect of the different ways of the herbicide application (drip irrigation and micro-sprinkling) on weed species forming the weed association in the row strip and their influence on the growth and fruiting habits of two cultivar-rootstock combinations were analyzed. The results obtained about the weed control efficacy of oxyfluorfen, applied in different ways, and the duration of the efficient herbicide activity, as well as the lack of a depressing effect on the growth and fruiting habits of the trees, gave the grounds to confirm the possibility of applying the herbicide through the micro-irrigation systems. The highest weed control efficiency was established in the variant of microsprinkling.
