Bio-herbicides: An eco-friendly approach for integrated weed management

Abstract

Bio-herbicides offer a promising eco-friendly alternative to chemical herbicides, addressing concerns over environmental impact and human health risks. These bio-controls, like Devine, Collego, and Biomal, are effective, economically feasible, and non-toxic to non-target organisms. They can significantly reduce weed-related crop yield losses, which account for 37% of overall pest-induced losses. However, the development of bio-herbicides requires careful consideration of formulation, fermentation systems, and strategic evaluation to ensure their effectiveness and commercial viability. To enhance the adoption and efficacy of bio-herbicides, researchers must address key constraints, including environmental, biological, technological, and commercial challenges. These constraints hinder the widespread use of bio-herbicides and limit their effectiveness as a sole weed management solution. While not a total replacement for chemical herbicides, bio-herbicides can serve as a vital component of integrated weed management systems, particularly as advancements in target selection, formulation, and marketing are made to overcome current limitations.
