ABSTRACT
Plant pathogens damage agriculture products to a large extent resulting in poor crop yield and quality. The well-followed practice to curb plant diseases are mostly involved with the application of conventional fungicides (synthetic chemical). However, their continuous and uncontrolled use has emerged as a big challenge for humans due to its hazardous effect on the environment. This can also lead to the development of resistance to plant pathogens. Green chemistry-based approaches have revolutionized the development of new strategies to curb plant diseases. Natural products mainly essential oils (EOs) have the potential to replace conventional fungicides to some extent. The current chapter aims to discuss the role of EO as biopesticide against plant pathogens (pests and fungal diseases).
