Abstract

Fusarium oxysporum f. sp. vasinfectum (FOV) (Atk.) W.C. Snyder & H.N. Hansen, incitant of cotton wilt, is a devastating pathogen of crop across the globe and characterised by more than 21 vegetative compatibility groups. To date, only one vegetative compatibility group FOV VCG0114 (Race 4) is known to infect cotton crop in India. However, during July 2024 emergence of a vascular-competent, nematode-dependent pathotype was recorded from Haryana (India). Whole genome based phylogenetic analysis supported by pathogenicity tests confirmed the associated causal organism as F. oxysporum f. sp. vasinfectum VCG 0111. To our knowledge, this is the seminal report of F. oxysporum f. sp. vasinfectum VCG 0111 (Race 1) inciting cotton wilt in India and it underscores the need for heightened vigilance and robust management strategies to mitigate the potential threat to cotton cultivation.

期刊介绍： Physiological and Molecular Plant Pathology provides an International forum for original research papers, reviews, and commentaries on all aspects of the molecular biology, biochemistry, physiology, histology and cytology, genetics and evolution of plant-microbe interactions. Papers on all kinds of infective pathogen, including viruses, prokaryotes, fungi, and nematodes, as well as mutualistic organisms such as Rhizobium and mycorrhyzal fungi, are acceptable as long as they have a bearing on the interaction between pathogen and plant.
