ORGANIC VERSUS INTEGRATED MANAGEMENT IN POME FRUIT IN EASTERN AUSTRIA - ENTOMOLOGICAL ASPECTS |
| Author: | F. Polesny |
| Abstract:
The seasonal development of arhropod fauna in an organic and IFP apple orchard was studied. The different spraying programme of organic and integrated fruit production did not cause big differences in the entomofauna of the trees. Population density of beneficials evolved rather similar under both management systems over the season. Only in the case of Forticula auricularia the number of individuals was much higher in the organic plot than in the IFP orchard. This correlates with the permanent aphid problem in the organic orchard. The frequent use of sulphur in low dosages in the organic orchard did not harm the Typhlodromus pyri population in practice. | |
