20.500.12556/DKUM-83913 Testiranje 0-residue pridelovalnega sistema jabolk magistrsko delo Testing 0-residue apple production V sezoni 2018 smo v nasadih jablan sort Gala, Fuji in Zlati delišes testirali 0-residue koncept varstva pred škodljivimi organizmi. Standardni intenzivni integriran škropilni program (V1) smo primerjali z dvema 0-residue škropilnima programoma V2 in V3. V programih V2 in V3 smo v drugem delu sezone, od začetka julija naprej, namesto kemičnih FFS uporabljali alternativne pripravke, ki jih uporabljamo v ekološki pridelavi. Izvajanje V2 in V3 škropilnega programa je zagotovilo skoraj enako učinkovito zatiranje bolezni in škodljivcev kot škropilni program V1. Zaradi izvajanja V2 in V3 škropilnih programov ni prišlo do značilnega znižanja pridelka in do značilnega znižanja deleža jabolk prvega razreda. Pri V2 in V3 smo značilno znižali število najdenih aktivnih snovi s koncentracijo nad 0,01 mg/kg in tudi parametra kumulativni % MRL in % ARFD, ki sta v trgovskih verigah zelo pomembna pri presoji sprejemljivosti jabolk za odkup. Pri programih V2 in V3 smo lahko dosegli zahtevana merila trgovskih verig. In the 2018 season, we tested the 0-residue concept of protection against harmful organisms in apple orchards of the Gala, Fuji and Golden Delicious varieties. The standard intensive integrated spraying program (V1) was compared with two 0-residue spraying programs V2 and V3. In the V2 and V3 programs, in the second part of the season, from the beginning of July onwards, we used alternative preparations that are used in organic production of apples instead of chemical plant protection products. The implementation of the V2 and V3 spraying programs was almost as effective in providing control over apple diseases and pests as the V1 spraying program. As a result of the implementation of the V2 and V3 spraying programs there was no significant decrease in yield and no significant decrease in the proportion of first-class apples. In V2 and V3 we significantly reduced the number of active pesticide substances found with a concentration above the 0.01 mg/kg level, as well as the parameters cumulative % MRL and % ARFD, which are very important in assessing the acceptability of apples for purchase by retail chains. With the V2 and V3 programs we were able to meet the demanding criteria of retail chains. 0-residue Gala Fuji Zlati delišes integrirana pridelava 0-residue Gala Fuji Golden Delicious integrated production true true false [A.
