Abstract:V poskusu, izvedenem v letih 2007, 2008 in 2009 v Sadjarskem centru Gačnik smo preučevali vpliv mreže proti toči na razvoj škodljivcev in bolezni jablane (Malus domestica B.). Poskus je potekal na jablanah sort 'Braburn', 'Fuji' in 'Gala', ki smo jih gojili pod protitočno mrežo in izven nje. Opazovali smo velikost populacije zelene jablanove uši, rdeče sadne pršice, jabolčnega zavijača in obseg napada poganjkov ter plodov od pepelaste plesni in jablanovega škrlupa. Protitočna mreža ni imela vpliva na razvoj populacij zelene jablanove uši. Populacije rdeče sadne pršice v letu 2008 so bile večje izven mreže pri sorti Gala. V preostalih letih, pri vseh preučevanih sortah mreža ni imela značilnega vpliva na pršico. Mreža tudi ni imela značilnega vpliva na velikost populacij jajčec uši, pršice ter na obseg črvivosti plodov od jabolčnega zavijača. Mreža je povzročila značilno manjši ulov metuljev zavijača na feromonske vabe znotraj nasada pod mrežo, v primerjavi z ulovom zunaj mreže. Stopnja napada poganjkov in plodov od jabolčnega škrlupa in pepelaste plesni na drevesih, gojenih pod mrežo, ni bila večja, kot pri drevju, gojenem izven mreže. Glede na rezultate naše raziskave lahko trdimo, da uporaba protitočnih mrež nima značilnega vpliva na razvoj preučevanih bolezni in škodljivcev jablane.

Title:EFFECT OF ANTI-HAIL NETS ON DEVELOPMENT OF PESTS AND DISEASES OF APPLES (Malus domestica B.)
Abstract:The influence of anti-hail net on the development of pests and diseases of apples (Malus domestica B.) was studied for three years (2007, 2008 and 2009) in the orchard of the Fruit Research Centre Maribor-Gačnik. By observing 'Braburn', 'Fuji' and 'Gala' apple trees covered by net and uncovered trees we have done a comparison on population density of the fallowing pests and diseases: green apple aphid, European red mite, codling moth, apple powdery mildew and apple scab. When observing populations of green apple aphid no differences in population densities were observed at net-covered or uncovered trees. In year 2008, the populations of red spider mite were greater on uncovered Gala trees. In years 2007 and 2009 at all three studied cultivars populations of the red spider mite were not statistically different between covered and uncovered trees. Use of net also did not influence significantly the number of aphid and red spider mite winter eggs attached to apple branches and the rate of fruits attacked by codling moth. Significantly less butterflies of codling moth were cot at pheromone traps placed on net-covered trees than at those positioned at uncovered trees. The severity of apple scab and powdery mildew on sprout and fruits of trees grown under net was not higher than in case of uncovered trees. According to the results of our study we can conclude that the use of anti-hail nets dose not influence significantly the development of studied apple pests and diseases.
