Crop production often results in abundant agricultural residues, and organic crop production suffers from an overabundance of weeds. Scientists Perez-Ruiz et al. recently showed that several gritty-textured residues, particularly those derived from maize cobs and olive pits, could abrade weed seedlings when propelled by air. Their use can contribute to the non-chemical control of weeds requested by organic farming and offers a potential solution to address herbicide-resistant weeds.
