EFFECT OF DRIP IRRIGATION ON ANTHRACNOSE DISEASE DEVELOPMENT IN A RECONVERTED TRADITIONAL OLIVE GROVE
The olive anthracnose is caused by a fungal pathogen of the genus Colletotrichum. Under favorable environmental conditions the disease can devastate a great part of field production. In rainy years the application of chemical treatments is difficult. So, the disease is not controlled. The aim of this study was to know if drip irrigation installed in a traditional adult olive grove (more than 50 years old) interacts with anthracnose disease. With this purpose three different volumes of water and a dry regime were used in a field trial. All the four modalities were done with and without fungicide treatment. A significant effect of irrigation on disease intensity was observed, mainly when fungicide treatment is applied.
