“…García-Galavís et al (2009) evaluated the susceptibility of the cultivars used in this assay to different pests and diseases and they found that rust fungal disease affected more intensively the OMO. Therefore, in organic plum orchards, in addition to optimizing the application of organic fertilizers, it is important to achieve adequate control mechanisms against rust disease or to use the least susceptible cultivars to this fungus.…”

“…In 2006 and 2007, most of the cultivars displayed similar values in both orchards, except for 'Angeleno' in 2006 (higher in the organic) and 'Red Beaut' in 2007 (higher in the conventional). In 2008In , 2009In , 2010In and 2011, a total of six, seven, nine and eight cultivars, respectively, showed significantly higher TCSA values in the CMO, showing mean increases of between from 15 to 20%. In these four years, the other cultivars also showed larger TCSA in the CMO, but without significant differences.…”

The growth, phenology and fruit yield of 14 Japanese plum cultivars (Prunus salicina Lindl) were studied in two newly established experimental orchards under organic and conventional management. The experiment was conducted during 2005-2011 in the province of Seville (SW Spain), an important region of Japanese plum culture. Trunk crosssection areas (TCSA), flowering, yield and tree defoliation before winter dormancy were analysed over several years. After one year, TCSA were larger in the organically managed orchard (OMO) for most of the cultivars, in the next two years they were equal, and from the fourth year, several cultivars showed significantly larger TCSA in the conventionally managed orchard (CMO). Flowering in the conventional orchard started from 2 to 6 days before and lasted for 3 to 5 days more than in the OMO. Several cultivars produced significantly more fruit in the CMO, being the average fruit yield in the organic orchard about 72% of the conventionally managed orchard. Autumn defoliation was significantly advanced in the organic orchard, especially in cultivars highly susceptible to rust (Tranzschelia pruni spinosae), a disease not adequately controlled in the organic orchard.
