Researchers at Stockholm University Develop Method to Reduce Chemical Load
Scientists at Stockholm University have developed an innovative technology that fundamentally changes approaches to plant protection. This new method of pesticide delivery, based on lignin nanoparticles, significantly reduces chemical usage, minimizes environmental risks, and lowers financial costs for the agricultural sector.

Lignin-Based Technology
University graduate student Matilda Andersson created a lignin nanoparticle—a natural polymer found in wood and a byproduct of the wood processing industry. By using fatty acid derivatives, she was able to modify lignin so that the particles could adhere to the waxy surface of plants and penetrate the protective layer of leaves.
Environmental and Economic Potential
The proposed technology enhances the effectiveness of pesticides, providing protection for plants against pests for 60 days while reducing the risk of environmental contamination. Currently, only 25% of the 4 million tons of pesticides used worldwide each year reach their target crops. The rest of the chemicals are lost due to evaporation, runoff, or other factors, causing significant environmental and economic damage.
According to MIT News, farmers worldwide spend about $60 billion on pesticides each year. Traditional pesticides are produced using fossil fuels, which contribute to greenhouse gas emissions that cause climate change. The development by Swedish scientists has significant potential to reduce chemical dependency in agriculture.
While alternative pest control methods already exist, such as traps or steam pasteurization, the new technology allows for more efficient use of pesticides, reducing their negative impact on the environment and human health. The team at Stockholm University is preparing to test the nanoparticles on commercial crops and plans to thoroughly analyze their effectiveness in real-world conditions.
If the technology proves effective, it could become a groundbreaking solution in sustainable agriculture, providing a balance between economic benefit and environmental safety.
