Randomized trial confirms Alternaria alternata as the cause of leaf spot disease in Sesbania cannabina, highlighting agricultural implications.

This research aims to identify the pathogen responsible for leaf spot disease in Sesbania cannabina.
Collected 30 symptomatic leaves from field plants for pathogen isolation.
Used molecular techniques including DNA extraction and sequencing of specific genes.
Conducted pathogenicity tests by inoculating Sesbania cannabina seedlings with spore suspensions.
Identified Alternaria alternata as the causal agent based on morphological observations and DNA sequencing.
Isolates showed 98.93% and 100% sequence identity with known A. alternata strains.
Koch's postulates were fulfilled, confirming the pathogen's role in leaf spot disease.

Wu et al. (2026) studied this question.
