20.500.12556/DKUM-68082 Preizkušanje insekticidov za zatiranje krvave uši (Eriosoma lanigerum Hausmann) na jablani Testing different insecticides for controling woolly aphid (eriosoma lanigerum h.) on apple trees V letu 2015 smo na posestvu Fakultete za kmetijstvo in biosistemske vede v nasadu jablan sorte 'Fuji' izvedli poskus, kjer smo analizirali, ali so najpogosteje uporabljena sredstva za zatiranje krvave uši res dovolj učinkovita. Preizkus smo naredili tudi z ekološkimi sredstvi in primerjali, ali so primerljiva tistim v integrirani pridelavi. Hkrati smo preverili, ali sama sredstva vplivajo na pojav krvavkinega najezdnika in stopnjo parazitiranosti uši. Skozi poskus smo ugotovili, da je pripravek Pirimor (pirimikarb) v dveh terminih uporabe dosegel najvišjo učinkovitost. Sledita mu pripravka NeemAzal (azadiraktin) in Karate (lambda-cihalotrin), najmanj učinkovit je bil pripravek Pyrinex (klorpirifos-metil), ki je tudi močno škodljiv za parazitoidno osico Aphelinus mali. Ekološka sredstva se niso pokazala kot povsem primerljiva integriranim, saj je bila njihova učinkovitost skoraj 50 % manjša. Izmed ekoloških sredstev bi po učinkovitosti za zatiranje krvave uši bil najbolj primeren pripravek NeemAzal (s 64 % učinkovitostjo). Delež od najezdnika parazitnih uši ni bil enak pri vseh programih, najmanj odstopanja je bilo med ekološkimi programi in programom z uporabo pripravka Pirimor, ostali pripravki so po škodljivosti za najezdnika močno odstopali. In 2015, on Faculty of Agriculture and Life Sciences, we did an experiment on apple cv. ‘Fuji’. We tested whether the most commonly used insecticides for Woolly Apple Aphid control are effective enough. We also made an experiment with insecticides suitable for organic apple production, which we compared with the ones that are used in integrated production. At the same time, we tested whether spraying programs influence the occurrence of parasitoid Aphelinus mali and the level of parasitism of woolly aphids. Results of research show that Pirimor preparation (pirimicarb) achieved the highest efficiency after two spraying periods. Less efficient are NeemAzal (azadirachtin) and Karate (landa-cihalotrin), and the least effective was the Pyrinex (chlorpyriphos-methyl) preparation, which is also very harmful to the parasitoid wasps Aphelinus mali. Ecological products did not prove to be comparable to integrated products, as their efficiency was almost 50 % lower. NeemAzal was the most suitable for aphid control in organic spray system, which reached 64 % efficiency after two spraying periods. The proportion of Woolly Apple Aphid parasitism was different between programs, there was the least variation between the ecological programs and the program using the Pirimor preparation, others had strong impact on parasitoid wasp. krvava uš (Eriosoma lanigerum H.) krvavkin najezdnik (Aphelinus mali H.) insekticidi zatiranje krvave uši Woolly Apple Aphid (Eriosoma lanigerum H.)
