A 67-year-old farmer in Chuzhou, China followed an AI chatbot's advice to apply flupyrimethalin, flusulfasulfaether, thiamethoxazine, and methyl salt to kill weeds and pests on his farm. The AI had provided helpful guidance for months, building his trust, but this recommendation was catastrophic: flusulfasulfaether is designed to kill broadleaf weeds in soybean fields, and sesame is a broadleaf plant. Additionally, the AI failed to specify that the herbicide should be applied only to affected areas, not across the entire field. The result was the death of approximately 24.7 acres of sesame seedlings.
- A Chinese farmer lost 24.7 acres of sesame seedlings after following an AI chatbot's recommendation to apply flusulfasulfaether—a herbicide designed to kill broadleaf weeds in soybean fields—across his entire crop.
- The farmer had built trust in the AI over months of successful advice, but the chatbot failed to warn him that sesame is a broadleaf plant vulnerable to the recommended chemical, or that it should be applied only to targeted areas.
- The incident reignited broader debate about AI liability, the limits of AI for critical decisions, and whether companies providing AI advice should bear financial responsibility for harmful recommendations.

Event AI explains the error
When the farmer returned to the AI to ask what happened, it revealed that flusulfasulfaether is primarily used for broadleaf weeds in soybean fields—not compatible with sesame, which is classified as a broadleaf plant. The AI also confirmed the herbicide should only be sprayed on affected areas, not broadcast across the entire field.

What people are saying verbatim
“The angry farmer said that the AI never warned him of the dangers of following its advice but, as any chatbot will tell you itself, it can make mistakes, misunderstand details, or rely on incomplete information.”

“What's especially ironic in this instance is that the farmer initially didn't trust the AI app, but he changed his mind after it proved helpful. Given the end result, he probably should have trusted his gut.”

I don't understand why so many people just blindly trust this shit. It's not hard to see for yourself how often it's just flat out wrong. Go ask it questions about something you're already knowledgeable on and within just a few questions it's going to give you some pure bullshit.

The AI isn't a human and shouldn't be replacing them, but enhancing them. This is the kind of drivel that the AI boosters are latching onto nowadays. If this magic tool is so magic at "enhancing" people, why isn't there any concrete evidence of this magic?

This is a really stupid comment because it seems to be implying that brawndo does not in fact have what plants crave. But it obviously does. Idiot. Its brawndo. It has what the plants crave.

A lot of people know a lot about one narrow subject, and because of that their opinions should carry weight on everything else, too.

And Google will give you the top answer of what it thinks is the best link (and ads), should you always trust that source? No.
