Cover crops for integrated weed, pest and disease management
Cover crops can disrupt pest and pathogen life cycles and suppress weeds. However, they can also act as a ‘green bridge’ and become weeds, so careful planning and management is required.
How do cover crops suppress weeds?
Cover crops can suppress weeds and volunteers by competing for light, water and nutrients. Some crops also release inhibitory chemical compounds from living or decomposing plant tissue.
