20.500.12556/DKUM-58103 UČINEK FUNGICIDOV NA RAZVOJ SKLADIŠČNIH BOLEZNI JABOLK IMPACT OF FUNGICIDES ON THE DISEASES OF STORED APPLES V letu 2000 smo v nasadu Sadjarstva Blanca v Loki pri Zidanem Mostu izvedli poskus na jablani sorte 'Zlati delišes'. Ugotavljali smo učinek fungicidov na razvoj skladiščnih bolezni. Enaindvajset dni pred obiranjem smo v nasadu izvedli škropljenje z naslednjimi aktivnimi snovmi ciprodinil, kaptan in krezoksim-metil. Sedem dni pred obiranjem pa z aktivnimi snovmi: ciprodinil, kaptan, krezoksim-metil, dikofluinad in tiram. Aktivne snovi najdemo v pripravkih pod komercialnimi imeni Chorus 75 WG, Captan M 45, Stroby WG, Euparen in Thiram 80 WG. Ugotavljali smo vpliv uporabljenih fungicidov in terminov tretiranja na razvoj skladiščnega škrlupa, grenke gnilobe in monilije. Pridelek jabolk smo skladiščili v kontrolirani atmosferi (vsebnost O2: 1,3-1,5%, CO2:1,5 - 1,7%, temperatura 1,5 °C) do 27. 3. 2001. Takrat smo opravili ocena zdravstvenega stanja plodov. Delež okuženih plodov v primeru tretiranja sedem dni pred obiranjem je znašal od 1,48 % do 2,97 %, pri tretiranju enaindvajset dni pred obiranjem pa od 2,04 % do 3,3 %. Rezultati poskusa so pokazali, da vrsta fitofarmacevtskega sredstva in čas njihove uporabe nista imela signifikantnega vpliva na zdravstveno stanje pridelka po izskladiščenju. The trial was carried out in season 2000 in the plantation of ‘Golden Delicious’ apples (Blanca at Loka near Zidani most) to study the effects of application of fungicides pre harvest on development of fungal storage diseases. Seven days prior to harvest plantation was treated with active ingredients: ciprodinil, captan, kresoxim-methyl, dichlofluanid and thyram which are found in the following fungicides Chorus 75 WG, Captan M 45, Stroby WG, Euparen and Thiram 80 WG and 21 days prior to harvest plots were treated with fungicides Chorus 75 WG, Captan M 45 or Stroby WG. Their efficacy to control storage scab, bitter rot and monilia rot was deteremined. Apples from trail plots were stored in a controlled atmosphere till 27th March 2001 (six and halve months), when the cooling chamber (conditions: O2: 1.3-1-5%, CO2: 1.5 – 1.7%, temperature 1.5 °C) was opened and disease rate assessment was done. The proportion of infected fruits, when considering the treatment 7 days prior to harvest, ranged from 1.48 % to 2.97 %. In case of treatment 21 days prior the harvest the portion of infected fruits ranged from 2.04 % to 3.3 %. The results of the experiment have shown that the type of plant protection product (fungicide) used 21 days before the harvest does not have a statistically significant effect on the yield of healthy fruits, as well any statistically significant differences in yield of healthy fruit for the treatment 7 days before harvest. jabolka Zlati delišes skladiščne bolezni fitofarmacevtska sredstva appple Golden delicious storage diseases fungicide true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-04-07 09:08:16 2016-04-15 10:58:16 2022-06-16 03:06:56 2019-07-11 10:28:38 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:7RBOWU2L VS_Zagorc_Ema_2016.pdf VS_Zagorc_Ema_2016.pdf 1 217F1FD43F0115F56ADDD79611FE7538 a7bab9e051c8d2d5880658683fb9de299e61faf06f379cf423b575f849b79d89 08cd6d28-7c0c-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=88121 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
