Citriculture is one of the most important agricultural activities for the country, especially for the state of São Paulo. However, the industry has faced serious phytosanitary challenges in recent decades. Among these challenges, Huanglongbing (HLB) disease stands out as it has no curative methods, spreads rapidly, and causes severe damage to fruit production and quality. As there is no cure for HLB, disease control is achieved through preventive intervention to prevent new infections in citrus plants. Faced with the challenge of disease progression in commercial orchards, new management methods for disease control have been studied in the thematic project entitled "Measures for the reduction of primary infections in the integrated management of Huanglongbing in the citrus belt of São Paulo: technical and economic feasibility" (process 2017/21460-0), in which the present project is included. The objective is to assess the benefits and costs associated with the new management methods developed in the thematic project, in order to enable the development of a cost-benefit or cost-effectiveness model for these methods. The Net Present Value (NPV) method will be used for economic valuation of field experiments, which will provide the benefit-cost ratio for economic feasibility analysis. Therefore, the aim is to calculate the benefit-cost of each proposed management strategy and compare the presented techniques, thus evaluating and indicating their respective technical and economic viability to decision-makers.
