A collaborative project titled ASTER, involving eight Mediterranean countries, including Turkey, aims to develop a biological control method against tomato pests and diseases, funded by the European Union's PRIMA program. Led by Prof. Dr. İsmail Karaca from Isparta University of Applied Sciences, the project will explore the use of natural products and beneficial insects to replace chemical control, promoting biodiversity and ecosystem balance. Over three years, the project will be implemented in partnership with institutions from Italy, Portugal, Spain, Greece, Tunisia, Algeria, and Morocco, with the goal of reducing environmental impact, preventing water pollution, and ensuring the production of healthy tomatoes. This initiative is significant for Turkey, the world's third-largest tomato producer, as it seeks to minimize the use of chemicals in tomato cultivation, reducing the risk of contamination and improving the sustainability of the tomato production industry.
