BIO-HERBICIDES FOR SUSTAINABLE AND ECO-FRIENDLY WEED CONTROL: A REVIEW

Weeds are the major cause of crop yield reduction. Synthetic chemical herbicides are very effective in weed control and accomplish the weed reduction up to large extent but, due to resistance development, they become less effective for weed control. There is a need requirement for suitable alternative of chemical herbicides. Bio-herbicides are upcoming products for sustainable weed control. Bioherbicides are the new approach , originated from living organisms or natural metabolites of plant for weed control. Bio-herbicides includes microbes- fungal, bacterial and viral pathogens and plant based products includes plant extract and essential oils. The bio-herbicide inhibit of physiological activities like nutrient uptake, photosynthesis etc and disrupt cellular functions like cell wall and cell membrane, hormone and toxic production etc. Different types of formulation have been developed to enhance the shelf life of different bioherbicides for successful commercialization.
