20.500.12556/DKUM-73259 Rezultati proučevanja insekticidov za zatiranje glogove bolšice (cacopsylla melanoneura f.) Investigation Results for Suitable Insecticides Controlling Hawthorn Psyllid (Cacopsylla melanoneura F.) V letu 2016 je bil na posestvu Fakultete za kmetijstvo in biosistemske vede Univerze v Mariboru izveden poskus proučevanja učinkovitosti različnih insekticidov za zatiranje glogove bolšice (Cacopsylla melanoneura Föerster). Izvedba poskusa je potekala v integriranih nasadih jablan sort Gala in Jonagold. Poskusne parcelice so zajemale 5 vrst in so segale v dolžino 30 m, razporejene pa so bile po parcelah v obliki šahovnice. Insekticidi so bili naneseni v različnih terminih in fenofazah razvoja jablan. Vrednotenje učinkovitosti škropilnih programov je potekalo sedem, štirinajst in enaidvajset dni po aplikaciji. Rezultati kažejo, da je za učinkovito zatiranje bolšice v integriranih sadovnjakih potrebna več kot dvakratna aplikacija insekticidov. V integriranem načinu proizvodnje je poterebnoizvesti tri do štiri aplikacije insekticidov. Prvo tretiranje je potrebno izvesti v fenofazi BBCH 07-08 oziroma pred cvetenjem. Drugo tretiranje se mora izvesti v fenofazi BBCH 50, v stadiju mišjega ušesca. Tretje tretiranje pa je potrebno izvesti med cvetenjem v fenofazi BBCH 65. Četrto tretiranje pa po cvetenju jablan v fenofazi BBCH 67. Insekticidi, ki so pokazali najvišjo učinkovitost in primernost uporabe v integrani pridelavi jabolk, so naslednji: Spada 200 EC, Trebon Up, Mavrik 240, Karate Zeon.fosmet, etofenproks, tau-fluvalinat in lambda-cihalotrin. In the year 2016, on the Faculty for agriculture and life sciences experiments were conducted to test effectiveness of different insecticides for control of hawthorn psyllid (Cacopsylla melanoneura Föerster). Insecticides were tested in apple plantations of Gala and Jonagold. Plantations were managed according to standard practice in integrated orchards. Experimental plots were five rows wide and were 30 meters in length. Control and experimental plots were arranged in chess pattern across experimental field. Treatments were conducted in different developmental phonological stages of apple trees. The insecticides effectiveness evaluations were conducted after seven, fourteen and twenty one days after the applications. Results show that under the Slovenian climate conditions there is a need for more than two treatments against pest. For integrated plantation there is need for three to four treatments in a year. First two treatments should be applied before apple bloom in BBCH 07-08 growth stage and BBCH 50. Third and fourth treatments should be applied at stage BBCH 65 during apple bloom and after apple bloom in stage BBCH 67. Insecticides which showed the highest effectiveness against hawthorn psyllid were next: Spada 200 EC, Trebon Up, Mavrik 240 and Karate Zeon. jablana (Malus domestica Borkh) glogova bolšica (Cacopsylla melanoneura Föerster) zatiranje insekticidi apple tree (Malus domestica Borkh) hawthorn psyllid (Cacopsylla melanoneura Foerster control of hawthorn psyllid insecticides true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2019-03-14 08:06:30 2019-04-03 10:59:30 2022-08-02 00:30:41 2019-07-11 19:50:35 2019 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:QPFQ3OZF MAG_Kuhl_Crtomir_2019.pdf MAG_Kuhl_Crtomir_2019.pdf 1 EE4BA9D874A140C6FC929E12F98F36EE 9eff61a042627b6cfd3cb5cc7050739b20f00c274858eddcc610c99e62890af8 ab30828e-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/24f062a3-5ffa-4ded-89e9-b9a6ad369ad1 https://dk.um.si/Dokument.php?lang=slv&id=133515 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
