Abstract

Plant-parasitic nematodes (PPNs) have emerged as a global threat to agriculture, resulting in severe crop losses. Previously, farmers relied on chemical nematicides for their control; however, their environmental and health risks have necessitated the search for sustainable and eco-friendly alternatives. Bacillus velezensis is a plant growth-promoting rhizobacterium (PGPR) that has emerged as a promising biocontrol agent due to its multifaceted antagonistic strategies. This review consolidates evidence on its mechanisms underlying its mode of action, such as nematicidal metabolites and induced systemic resistance (ISR), alongside progress in formulation and field performance. By outlining both current successes and critical research gaps, this review aims to guide the development of practical B. velezensis-based strategies for sustainable agriculture.
