Climate change has exacerbated mango cultivation challenges, particularly in tree scarification and floral diseases, significantly impacting fruit yield and quality. This study investigates the effectiveness of exogenous applications of synthetic chemicals in mitigating these climate-driven stresses, focusing on the commercially important mango cultivar ‘Chaunsa Summer Bahisht’. Field trials were conducted to assess the efficacy of different chemical treatments, including fungicides and stress-mitigating compounds, on scarification prevention and floral diseases control. Results demonstrated a significant reduction in tree scarification rates and floral disease incidence in treated trees compared to untreated controls. Improved floral retention, reduced necrosis, and enhanced fruit set were observed, suggesting the potential of these interventions to counteract adverse climatic effects. Moreover, the treatments enhanced physiological parameters such as chlorophyll content and photosynthetic efficiency, contributing to overall tree health. The study underscores the role of targeted chemical applications in safeguarding mango production against climate variability. However, careful management of chemical use is recommended to ensure environmental sustainability and compliance with food safety standards. This case study highlights the need for integrated approaches to manage climate-induced stresses in mango orchards, ensuring long-term productivity and quality of this economically significant crop.
