Abstract:V triletnem poskusu (2011-2013) smo preučevali posledice izločitve uporabe bakrovih fungicidov iz škropilnih programov za varstvo breskev pred glivičnimi boleznimi v nasadih z ekološko ali integrirano pridelavo. Primerjali smo 4 tipe škropilnih programov: ekološki škropilni program, ki je temeljil na uporabi žvepla, kislih glin in karbonatnih pripravkov (ECO), ECO + uporaba bakrovih fungicidov, integriran škropilni program, ki je temeljil na uporabi organskih fungicidov (ciram, ciprodnil, penkonazol, dodin, fenheksamid in drugi) (INT) in INT + uporaba bakrovih fungicidov. Z uporabo standardnih EPPO metod z vizualnim ocenjevanjem stopnje napada in izračunom učinkovitosti po Abbotu smo ugotavljali učinkovitost škropilnih programov za zatiranje bolezni, ki jih povzročajo glive Taphrina deformans, Clasterosporium carpophillum, Monilia sp., Phomopsis amygdali, Sphaerotheca pannosa and Colletotrichum gloeosporioides. Zaradi izločitve bakrovih pripravkov iz uporabe se je učinkovitost škropilnih programov zmanjšala pri vseh preučevanih boleznih. Izjema je bila pepelasta plesen. Rezultati poskusa kažejo, da imajo bakrovi pripravki pri zatiranju bolezni breskev še vedno nenadomestljivo vlogo. Dolgoročna neuporaba bakrovih pripravkov lahko značilno poveča infekcijski potencial preučevanih gliv in zmanjša rodnostno kapaciteto dreves. Ker uporabe bakrovih pripravkov trenutno ne moremo popolnoma izključiti iz škropilnih programov je potrebno najti nove formulacije bakrovih fungicidov, ki so učinkovite pri bistveno nižjih odmerkih na hektar, da bo bomo lahko zagotavljali visok nivo varstva pred boleznimi do obdobja, ko bodo na trgu na voljo učinkoviti alternativni pripravki.

Title:ANALYSIS OF POSSIBILITIES FOR PEACH (Prunus persica L.) DISEASE CONTROL WITHOUT USE OF COPPER BASED PESTICIDES
Abstract:A three-year field trial (2011, 2012 and 2013) was conducted to determine the consequences of excluding copper fungicides from spray programs for control of fungal diseases of peach in organic and integrated peach production. Four types of spray programs were compared: an organic spray program based on sulfur, acid clay and carbonate preparations (ECO), ECO + copper products (ECOCu), an integrated spray program based on organic fungicides (ziram, cyprodnil, penconazol, dodin, fenhexamid, etc.) (INT) and INT + copper products (INTCu). The efficacy of the spray programs for control of diseases caused by Taphrina deformans, Clasterosporium carpophillum, Monila sp., Phomopsis amygdali, Sphaerotheca pannosa and Colletotrichum gloeosporioides was assessed by standard EPPO methods using visual disease rate scoring and efficacy calculation according to the Abbot formula. The efficacy for disease control decreased following the exclusion of copper products from the spray programs. The only exception was powdery mildew. The results of the trial show that copper fungicides play an irreplaceable role in managing peach diseases and their long-term exclusion can cause a significant increase in the infective potential of the studied diseases and a decline in peach tree yielding capacity. Since currently copper fungicides cannot be excluded from spray programs, completely new copper fungicide formulations exhibiting efficacy at much lower rates per hectare are needed to ensure good disease control until equally efficient alternative fungicides are developed and available on the market.
