AI recommendations in agriculture are becoming increasingly popular among farmers who want quick guidance on irrigation, pest control, and crop protection. However, a recent case in China shows that relying on these tools without expert review can lead to serious losses.

A 67-year-old Chinese farmer lost a sesame crop covering nearly 25 acres, or about 100 dunams, after following a mistaken recommendation from an AI-powered app. The incident shows that AI recommendations in agriculture can be useful, but they should never replace human expertise.

How the Crop Was Destroyed

According to reports, the farmer had been using an AI app for agricultural advice related to weeds and pests. Over time, he began trusting the system because some of its earlier suggestions had worked well.

The problem came when the app suggested a chemical mixture to deal with the crop issue. One of the products was a herbicide designed for broadleaf weeds. That was a critical mistake, because sesame is also a broadleaf plant.

As a result, the herbicide damaged the crop instead of protecting it. Soon after spraying, the seedlings began to wilt and die, and by the next day, the field had suffered extensive damage.

Why AI Can Make Mistakes in Farming

The main issue is that AI recommendations in agriculture, especially from general-purpose language models, are not always aware of local farming conditions. These systems can generate answers that sound convincing but may miss important details such as:

• crop type
• growth stage
• soil conditions
• herbicide concentration
• weather
• humidity
• local regulations

Because of this, an answer that seems correct in one situation may be dangerous in another. In farming, even a small error in the product name, dosage, or application timing can destroy an entire crop.

Major Financial Losses

Reports suggest that the damage covered around 25 acres, which is roughly 150 mu in Chinese agricultural measurement. The financial loss was estimated at about 150,000 yuan, or around $20,700.

This case shows that AI recommendations in agriculture can be helpful only when they are reviewed and verified. Without that step, a simple mistake can become a very expensive one.

Warnings About AI and Pesticides

Experts and researchers have warned against blindly trusting AI when choosing agricultural chemicals. Some systems may recommend products that are unsuitable for the crop or not legally registered for use.

Using pesticides incorrectly can damage crops, harm the environment, and create health risks for farm workers. For this reason, specialists always recommend checking the official pesticide label and consulting an agronomist before applying any AI-generated advice.

Is AI Useful in Agriculture?

Despite this incident, AI is still very useful in farming. It can support farmers in many ways, including:

• detecting plant diseases
• monitoring crop health
• analyzing field images
• estimating irrigation needs
• predicting agricultural stress
• supporting decision-making

However, AI works best as a support tool, not as the final decision-maker. AI recommendations in agriculture should be combined with reliable data and human expertise.

A Lesson for Farmers

This story offers an important lesson for anyone using AI in farming. AI can save time and provide quick answers, but it is not a substitute for field experience or expert review.

When pesticides, crops, or application rates are involved, human verification is essential. Farmers need answers that are not only fast, but also accurate, safe, and suitable for local conditions.
