[Farmer Grandpa Asks AI How to Remove Weeds, AI Provides Toxic Formula That Kills All Crops] According to monitoring by Dongcha Beating, a 67-year-old farmer, Mr. Wu from Chuzhou, Anhui, consulted a national AI chatbot on how to remove weeds and pests from his sesame field. The AI quickly generated a pesticide formula. Following the instructions, he sprayed it, and by the next day, 150 acres of sesame and weeds had withered together, resulting in a near-total loss of a harvest worth tens of thousands of yuan. The issue lay in the formula's inclusion of "Flumioxazin." This herbicide is primarily used for soybean fields, but sesame seedlings are more sensitive to it. Local agricultural technicians stated that this chemical should not be sprayed across an entire sesame field. Spraying it is equivalent to clearing both crops and weeds together. After the damage, Mr. Wu questioned the AI about the cause, and it responded that Flumioxazin was likely the main reason for the sesame seedlings' death. The AI initially provided an incorrect formula with a serious tone, and only after 150 acres were ruined did it analyze its own mistake. Customer service from the platform involved stated they would investigate the source of the erroneous information but have yet to announce a compensation plan. While the AI's answers can be revised at any time, pesticides sprayed onto the field have no "undo" button. [Original Link]
