- Abstract :Fire blight disease, caused by Erwinia amylovora (Burrill), emerged as a devastating pathogen in Tunisia in spring 2012, causing catastrophic losses to the national pear and apple industry (Rhouma et al., 2014). Since its first detection in the Morneg region (Ben Arous governorate), the disease has spread rapidly throughout northern Tunisia, destroying more than 5,500 hectares of pear plantations (approximately 65% of total cultivated area) and reducing national pear production from 60,000 metric tons in 2011 to less than 20,000 metric tons by 2016 (Rhouma et al., 2014; Gaaliche et al., 2018). This review synthesizes significant research achievements by Tunisian scientists in understanding and combating fire blight since 2012. Major accomplishments include: establishment of pathogen identity through rigorous microbiological and molecular characterization (Rhouma et al., 2014; Bouazizi et al., 2025); comprehensive epidemiological assessment across all major production regions (Gaaliche et al., 2018); evaluation of cultivar susceptibility patterns and identification of resistance mechanisms (Gaaliche et al., 2018; Bouazizi et al., 2020); investigation of population genetic diversity and structure of E. amylovora isolates; characterization of virulence variability among pathogen populations; identification of molecular mechanisms underlying host defense responses including antioxidant systems and salicylic acid signaling (Bouazizi et al., 2020); isolation and characterization of bacteriophages with potential for biological control; and investigation of pathogenic determinants at the molecular level, including virulence gene regulation and metabolic signaling in the plant apoplast (Jeridi, 2022).

- Abstract :The use of satellite imagery in agriculture has transformed how farmers monitor crop health, allowing them to make informed decisions based on real-time data. By analyzing multispectral and hyper spectral images, farmers can effectively track the growth stages of crops and identify stress patterns. This leads to improved management strategies and timely interventions that help prevent performance losses. The combination of satellite data, geographic information systems (GIS) and crop modelling enhances predictive capabilities, optimizing planting and harvesting schedules. As a result, farmers experience substantial economic benefits, including increased crop yields and greater profitability. This review examines the significant impact of satellite technologies on farming practices, high lighting the importance of monitoring environmental factors, including soil moisture, temperature, and pest infestations.
