Therefore, first, disease incidence was compared in standard and reduced spray programmes and then each technological variation was evaluated from practical point of view. Altogether four spray programmes were compared. Standard and reduced spray programmes were performed in the integrated production. The same pesticides were used in the reduced spray programme compared to standard one but numbers of spray were reduced by 25% at the second half of the season. Standard and reduced spray programmes were also performed in the organic production and the numbers of spray were reduced by 40% in the reduced spray programme. Incidence of diseases was low in both standard and reduced spray programmes in integrated production. Diseases level was high in the organic production and disease increased significantly in the reduced spray programmes compared to standard programmes. Results showed that reduction in spray numbers at the second half of the season can be used practically in integrated production. Omission of sprays in organic production resulted in serious disease management risk; therefore, it is not recommended for practical use.Tétel Szabadon hozzáférhető Előzetes vizsgálatok a Venturia inaequalis populációk in vitro érzékenységére egyes fungicid-hatóanyagokkal szemben(2012) Fazekas, Mónika; Abonyi, Ferenc; Balla, Barbara; Lakatos, Péter; Holb, ImreTétel Szabadon hozzáférhető Fruit injury in organic fruit production and its relationship to brown rot caused by Monilinia spp.(2016) Abonyi, Ferenc; Vámos, Alex; Lakatos, P.; Rózsa, A.; Holb, ImreTétel Szabadon hozzáférhető In vitro sensitivity of Monilinia laxa to fungicides approved in integrated and organic production systems(2011) Holb, Imre; Fazekas, Mónika; Abonyi, FerencTétel Szabadon hozzáférhető Micro area based spatial distribution of apple scab in an organic apple orchard(2015) Holb, Imre; Lakatos, Péter; Abonyi, FerencTétel Szabadon hozzáférhető Preliminary studies on in vitro sensitivity of Venturia inaequalis populations to some fungicide active ingredients(2012-12-16) Fazekas, Mónika; Abonyi, Ferenc; Balla, Barbara; Lakatos, Péter; Holb, ImreAim of this study was to investigate the sensitivity of conidia of Spilocaea pomi to main fungicide active ingredients (cyprodinil, pirimethanil, fluquinconazole, tebuconazole, difenoconazole, dodine és trifloxistrobin) at dosages of 0.5, 1 and 2 times incubated in vitro at 24 and 48 hours collected from three integrated apple orchards. Results showed that degree of conidial germinations at the fungicide treatnemts decreased in the order of dosages of untreated, 0.5, 1 and 2 times. Considerable conidial germination was observed at higher dosages of some fungicides (e.g. groups of strobilurines and EBI) which confirmed the possibilities of sensitivity reduction of Spilocaea pomi to some funigicides in the sampled Hungarian apple orchards.Tétel Szabadon hozzáférhető Preliminary study on micro area based spatial distribution of Monilinia fructigena in an organic apple orchard(2014) Holb, Imre; Rózsa, A.; Abonyi, FerencTétel Szabadon hozzáférhető Some aspects of reduced disease management against Blumeriella jaapii in sour cherry production(2011) Holb, Imre; Vámos, Alex; Lakatos, Péter; Gáll, József; Abonyi, FerencTétel Szabadon hozzáférhető Some aspects of reduced disease management against Monilinia spp. In sour cherry production(2010) Fazekas, Mónika; Abonyi, Ferenc; Madar, Anett; Lakatos, Péter; Gáll, József; Holb, ImreTétel Szabadon hozzáférhető Spore dispersal, diurnal pattern and viability of Monilinia spp. conidia and the relationship with weather components in an organic apple orchard(2015) Abonyi, Ferenc; Vámos, Alex; Rózsa, Attila; Lakatos, Péter; Holb, Imre
