Plant immunity inducers have emerged as a promising and innovative approach in plant protection. Unlike traditional chemical fungicides that target pathogens directly, these inducers activate the plant’s innate immune system to enhance resistance against diseases. Traditionally, chemical pesticides have been widely employed to control these pathogens due to their ability to directly kill harmful organisms. Although breeding for disease-resistant crop varieties remains a key approach, utilising immunity inducers offers a more sustainable and eco-friendly method for disease management. Advances in understanding plant immune mechanisms have facilitated the development of such inducers, which involve key immune-related proteins and pathways. This review examines the fundamental concepts of plant immunity inducers, highlights their key active molecules, and explores their practical uses in horticultural practices. It also discusses recent improvements, including their use alongside beneficial microorganisms and fertilisers, as well as the design of synthetic compounds that specifically engage plant immune receptors. Despite challenges related to large-scale production and field effectiveness, ongoing research continues to improve these sustainable plant protection strategies. Overall, plant immunity inducers offer a valuable and eco-friendly alternative for improving crop health and securing global food production.
