Containing perennial weeds with the bioherbicide pelargonic acid through direct control and support of cover crop management

Perennial weeds like Cirsium arvense and Sonchus arvensis pose serious challenges in conventional and organic farming. Due to health and environmental risks, reducing synthetic herbicide use is vital. With herbicides such as glyphosate under restrictions, bio-based herbicides like pelargonic acid (PA) are being explored. This thesis aimed to evaluate strategies to enhance PA efficacy and explore its potential in managing both perennial weeds and cover crops, and addressing existing gaps and limitations.
