What happened

A 67-year-old farmer in Chuzhou, Anhui, reportedly used an AI-generated weed-and-pest-control plan to spray about 150 mu (25 acres) of sesame by drone. By the next day, the crop had largely withered. Agricultural technicians said the recommended mixture included fomesafen, a herbicide unsuitable for blanket application to sesame. The specific AI product and model have not been publicly confirmed.
