| South Tyrol, the main Italian apple growing area, is characterised by an highly intensive soil cultivation. Previous investigations shows the existence of replant disorders although it has not been evaluated which are the main causes. A survey has been carried out in this area with two main aims I) to evaluate the role of soil borne pathogens in apple replant disease and II) to evaluate the effect of soil management toward soil borne pathogens causing replant diseases. The experimental sites were chosen in order to obtain three couples of contiguous conventional and organic apple orchards. Soil sickness test with young apple plants gave a significant growth reduction in all soil samples if compared to a peat control. Among all root colonising fungi... |

| Field mice (Microtus arvalis), wood mice (Apodemus sylvaticus) and root voles (Arvicola terrestis) constitute a big threat to the organic apple orchards in South Tyrol. The use of rodenticides on the fields is not allowed in organic farming. The fruit growers rely on the help of different natural predators. If populations increase, the possibility of trapping and gasifying with equipment which produces carbon monoxide and carbon dioxide remain. Both methods are problematic. Trapping requires skill and time. Gasifying is not unproblematic to the health of the user. Recently a device has been imported which is used successfully in the United States to control different soil-dwelling rodents. In the orchards of South Tyrol, various field trials were... |
