Japan uses lactic acid bacteria to produce pesticides
2025-10-09 03:06:11
A Japanese research team has developed a novel "lactic acid bacteria pesticide" that leverages the antibacterial properties of lactic acid bacteria to protect crops from two common diseases. This innovative approach, reported by Japanese media on the 20th, was created by the Kyoto Prefecture Agricultural Resources Research Center using *Pediococcus acidi* as a key ingredient.
The pesticide is formulated into a liquid solution, which is used to soak spinach seeds for 24 hours before planting. When these treated seeds were sown in soil infected with the pathogen causing spinach wilt, only about 12% of the resulting spinach plants showed signs of infection. Similarly, when pepper seedlings were treated with *Pediococcus acidiformis*, the risk of root rot caused by harmful bacteria was reduced to approximately 20% of the level seen in untreated plants.
Researchers are currently conducting further tests to evaluate the effectiveness of this new pesticide on other crops and to confirm its safety for human use. If all trials are successful, the product is expected to become commercially available around 2012.
According to the project leader, the "lactic acid bacteria pesticide" does not contain any chemical additives, making it an attractive option for consumers who are increasingly concerned about food safety. However, the production process is labor-intensive, and the final cost is likely to be relatively high. Despite this, the technology represents a promising step toward more sustainable and eco-friendly agricultural practices.
