20.500.12556/DKUM-84348 Primerjava kakovosti nanosa FFS v nasadu jablan z ali brez uporabe elektrostatske podpore in kakovosti nanosa pri vožnji po vsaki ali vsaki drugi vrsti magistrsko delo Comparison of PPP Application Quality in Apple Orchards With or Without the Use of Electrostatic Support and Application Quality When Driving Through Every or Every Other Row Raziskava je bila izvedena v letu 2021 v ekološkem sadovnjaku podjetja Evrosad, d. o. o., v Savcih na sorti zlati delišes. Cilj naloge je bil preveriti učinkovitost zatiranja bolezni in škodljivcev jablane pri uporabi elektrostatskega nanosa z enako porabo vode in ob enakih delovnih parametrih kot pri nanosu brez elektrostatske podpore. Prav tako smo testirali učinkovitost škropljenja z uporabo elektrostatskega nanosa pri škropljenju vsake druge vrste jablan. Za oceno enakomernosti porazdelitve škropilne brozge smo uporabili tehniko vodoobčutljivih lističev. Kakovost depozita škropilne brozge smo ocenili z uporabo barvnega sledilca tartrazin, katerega koncentracijo na listih smo določili z uporabo fotospektrometra. Ocena stopnje napada zaradi bolezni in škodljivcev je bila večkrat letno narejena po standardnih metodah EPPO, pri čemer smo uporabili metodo vizualnega bonitiranja deleža napadene površine opazovanega organa. V poskusu pri danih parametrih nismo potrdili postavljenih hipotez, da uporaba elektrostatike značilno izboljša uspešnost zatiranja škodljivih organizmov in da lahko škropljenje preko dveh vrst ob uporabi elektrostatike daje enakovreden rezultat kot škropljenje vsake vrste nasada jablan. The study was carried out in 2021 in the organic orchard of the Evrosad d.o.o. company in Savci, namely on the Golden Delicious apple variety. The objective was to verify the effectiveness of the disease and pest control in apple trees using an electrostatic spray application, with the same water consumption and the same working parameters as the application without electrostatic support. We also tested the effectiveness of using the electrostatic application when spraying every, or only every second apple tree row. The water-sensitive paper technique was used to assess the uniformity of spray distribution. The quality of the spray deposit was characterised using the colour tracer tartrazine, the concentration of which was determined using a photospectrometer on the leaves. The assessment of the level of diseases and pest infestation was made several times a year according to the standard EPPO methods, using the method of visual rating of infested surface area proportion at the organ observed. For the given parameters, we were unable to confirm the hypotheses that the use of electrostatics significantly improves the success of pest control and that spraying over two rows using electrostatics can give an equivalent result in comparison to spraying each row of an apple orchard. fitofarmacevtska sredstva elektrostatska podpora pršenje plant protection products electrostatic support spraying true true false V.
