Investigation reveals Alternaria alternata induces significant leaf spot symptoms in Schefflera heptaphylla, suggesting further management strategies.

Key Points

The identification of Alternaria alternata as the cause of leaf spot on Schefflera heptaphylla was confirmed through pathogenicity testing.
Infection affected approximately 70% of plants in a nursery, leading to substantial economic losses for growers.
Detailed characterization involved DNA sequencing and a phylogenetic tree analysis, confirming the fungal isolate as A. alternata.
This report marks the first confirmed instance of A. alternata causing leaf spot in S. heptaphylla in China, highlighting the need for management practices.
