SANITARY STATUS AND SANITATION OF STONE FRUIT TREES IN SOUTH EAST ITALY |
| Authors: | B. Di Terlizzi, V. Savino |
| Abstract:
In Apulia the phytosanitary status of fruit tree crops is unsatisfactory much the same as in other Italian regions, but it is improving thanks to the adoption of preventive measures, such as the use of “virus tested” budwood. To this effect, a regional programme for the certification of propagating material produced by local nurseries was established. Sanitary selection was carried out in the main horticultural areas of Apulia by visual inspection, mechanical transmissions onto herbaceous hosts and immunoenzymatic tests (ELISA). The minimum requirements for admission to the certification scheme were absence from Prunus necrotic ring spot (PNRSV), apple mosaic (ApMV), prune dwarf (PDV) ilarviruses, apple chlorotic leaf spot trichovirus (ACLSV) and plum pox potyvirus (PPV). For many cultivars it was not possible to indentify candidate mother plants of a sanitary condition compatible with certification requirements. Thus, heat therapy (two months exposure to 38°C in an artificially lighted heat cabinet, removal of shoots tips or buds to be grafted onto healthy rootstocks) was applied whenewer necessary. | |
