Biostimulants for Citrus: Organic Orange, Lemon and Mandarin<\/h1>\n\n\n\n
\"\"<\/figure>\n\n\n\n
\"\"<\/figure>\n\n\n## Organic Citrus Cultivation: A Booming Sector\n\nOrganic citrus cultivation is establishing itself as one of the most dynamic and promising agricultural sectors. In Spain, approximately 350,000 hectares of citrus are cultivated, with 15% dedicated to organic production. The regions of Valencia, Murcia, and Andalusia are the main producers, significantly contributing to the 4.5 million tonnes of citrus that Spain exports annually to the European Union market.\n\nThe organic citrus market has seen a remarkable increase, with prices exceeding those of conventional citrus by 35-60%. This rise is partly due to the growing demand for zero-residue products, especially in Nordic markets. Organic mandarins, in particular, have shown an annual growth of 25%, standing out as the fastest-growing segment within the sector.\n\n## Agronomic Requirements by Citrus Species\n\nEach citrus species has specific agronomic needs to achieve optimal growth and high-quality production. Below is a table with the most important requirements for the main cultivated species:\n\n\n \n \n \n \n \n \n \n \n

The main diseases include:\n\n– **Phytophthora citrophthora**: Causes gummosis and root rot. Biostimulants can help strengthen the plant’s natural defenses.\n– **Alternaria alternata**: Causes brown spot in mandarins. The application of biostimulants enhances the plant’s natural resistance.\n– **Colletotrichum gloeosporioides**: Responsible for anthracnose in citrus. Biostimulants can reduce incidence by fortifying plant tissue.\n– **Mycosphaerella citri**: Causes greasy spot. The use of biostimulants helps reduce the impact of this disease.\n– **Fruit drop in June and October**: A common problem that can be mitigated with appropriate nutritional strategies.\n– **Nutritional deficiencies**: Iron chlorosis, zinc (Zn), manganese (Mn), and boron (B) deficiencies are common. Biostimulants can efficiently correct these deficiencies.\n– **Mites**: Without synthetic acaricides, control relies on cultural practices and biostimulant applications.\n\n## Ecoganic Biostimulant Programme for Citrus Phase by Phase\n\nThe use of certified organic biostimulants from Ecoganic, such as Boost Universal and Balance 7-7-7, helps optimise citrus yield at each stage of development:\n\n\n \n \n \n \n \n \n \n \n \n \n \n \n
