Alternaria alternata is a cosmopolitan phytopathogenic fungus exhibiting broad host range and remarkable ecological adaptability. The present study investigates its host range variability, infection dynamics and relative abundance across twenty-two naturally infected plant species belonging to eighteen families collected from different localities within the Amravati Division of Maharashtra, India. Field-based observations, host-specific symptomatology, and herbarium-supported documentation reveal significant variations in susceptibility, lesion morphology, and ecological associations. The results highlight the wide natural host spectrum of A. alternata in the region from fruit trees and forest species to ornamentals and cultivated crops emphasizing its epidemiological significance and potential impact on local biodiversity and agriculture. The study contributes to understanding host-pathogen interactions and provides baseline data for disease monitoring and management strategies in the Amravati Division.
