Allelopathy is a natural process where plants release chemicals (allelochemicals) that influence the growth of other plants, offering eco-friendly solutions for weed control and sustainable farming. It helps in weed management, crop productivity, pest control, and ecosystem balance, reducing reliance on synthetic herbicides. Key management strategies include residue incorporation, crop rotation, intercropping, mulching, and cover cropping to enhance soil health and suppress weeds. Future research focuses on identifying and commercializing allelochemicals, improving bioherbicides, and integrating allelopathic traits into crops. Allelopathy presents a promising, sustainable alternative to chemical herbicides, promoting environmentally friendly agriculture.
