Weed plants are one of the main constraints to agriculture and cause considerable crop yield loss besides reducing product quality and leading to health and environmental threats. In comparison to various weed management strategies, biological control-especially mycoherbicides-offer an innovative approach to address this problem. Today, the bio-control of weeds by mycoherbicide (either fungal spore suspension or their metabolites) has received significant academic attention and over the past few decades some of the high profile candidates became commercially available. Employing mycoherbicide proposes benefits including being environ-mentally friendly, cost effective, and identifying new herbicidal mechanisms. This review focuses on challenges that mycoherbicides encounter before their adoption. Besides, important factors in both selecting and improving a fungal strain as a mycoherbicide are reviewed. Additionally, using integrated weed management as complementary methods to elevate the efficacy of mycoherbicides have been considered.
