20.500.12556/DKUM-67934 Testiranje ekoloških škropilnih programov za zatiranje glogove bolšice (Cacopsylla melanoneura Förster) Organic Spray Programs testing for Controlling the Hawthorn Psyllid (Cacopsylla melanoneura Förster) V ekološkem nasadu jablan smo izvedli klasičen poljski poskus, kjer smo primerjali učinkovitosti petih različnih ekoloških škropilnih programov za zatiranje glogove bolšice Cacopsylla melanoneura Förster. Za analizo so bile uporabljene tri metode pri različnih razvojnih stadijih jablan in bolšic. Za opravljanje primerjave učinkovitosti smo podatke o velikosti populacije vnesli v Abbotovo in Henderson-Tilton formulo. Testirane so bile naslednje aktivne snovi: naravni piretrini z oljem (Raptol), azadirahtin (Neemazal T/S), parafinsko mineralno olje (Frutapon), kaolinitna glina (Cutisan), raztopina mineralov (Mineral Rdeči), eterična olja iz lupin agrumov (Oranol), pomešana eterična olja (Matrinal B) in kalijeve maščobne snovi (Aktiv). Ekološki pripravki so na splošno dosegli dokaj visoko stopnjo učinkovitosti, med njimi pa so obstajale statistično značilne razlike. Zatiranje nimf bolšic je lažje kot zatiranje odraslih vektorjev. Na učinkovitost vplivata zaporedje uporabe pripravkov in termin nanosa. Field trials were carried out at an apple plantation to compare the efficiency of five different organic spray programs for controlling the hawthorn psyllid (Cacopsylla melanoneura Förster). Three methods were used to analyze different development stages of the apples and the psyllids. Data on the population size was entered into Abbott’s and Henderson-Tilton formulas in order to compare the above-mentioned efficiencies. The following insecticide active substances were tested: natural pyrethrins with oil (Raptol), azadirachtin (Neemazal T/S), paraffin mineral oil (Frutapon), kaolin clay (Cutisan), mineral solution (Mineral Red), essential oils derived from citrus peels (Oranol), mixed essential oils (Matrinal B) and potassium salts of fatty acids (Aktiv). The organic insecticides achieved a high degree of efficiency in general, however, there also were statistically significant differences. In conclusion, it is easier to control the psyllid nymphs than adult vectors. The level of efficiency depends on the sequence and time intervals of insecticide application. jablana glogova bolšica metličavost jablan škropilni programi ekološki pripravki apple tree hawthorn psyllid apple proliferation spray programs organic insecticides true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-04 11:21:45 2017-09-22 07:40:09 2022-08-01 14:38:18 2019-07-11 14:57:51 2017 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:BYXH5MEB UN_Rihter_Erik_2017.pdf UN_Rihter_Erik_2017.pdf 1 77D3036041EF34EA734E0AE9BCCB207E 609908282475c6fde6d713cfb6e999eaf73f1725c572711cb46b216683497008 5dce4b62-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/ef776675-5520-4212-8cdb-e85f502ebfd7 https://dk.um.si/Dokument.php?lang=slv&id=118975 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
