Data and R scripts for the article "Plant Protection Products to Control Alternaria Brown Spot Caused by Alternaria alternata in Citrus: A Systematic Review", published at Agronomy in may 2025. DOI: 10.3390/agronomy15061343 Alternaria brown spot is the most critical disease for susceptible mandarins (Minneola, Murcott, Nova, etc.) worldwide and it is a limiting factor for their cultivation. Although there are numerous reports on effective substances to control the disease, field control is failing. In this paper we collate, analyze, and synthesize the most relevant empirical evidence to answer the following questions: (i) What substances have been used to control ABS and what how effective are they? (ii) What are the methodologies used to test the substances? (iii) Why is ABS field control failing, and what are the main factors hindering such control? An extensive literature search was performed in five databases: WoS, Scopus, Google Academics, PubMed, and Scielo. The search string used was “Alternaria alternata” AND “Citrus”. Records were classified into 10 groups according to their main topic. Group 3 “natural substances” and Group 4 “fungicides” were full-text reviewed for data extraction (98 reports).
