Japan uses lactic acid bacteria to produce pesticides

A Japanese research team has developed a groundbreaking "lactic acid bacteria pesticide" by harnessing the natural antibacterial properties of *Pediococcus acidi*. This innovative approach helps prevent two common crop diseases, offering a promising alternative to traditional chemical pesticides.
According to a recent report from Japanese media, the Kyoto Prefecture Agricultural Resources Research Center created this eco-friendly pesticide by processing *Pediococcus acidi* into a liquid solution. The treatment involves soaking spinach seeds in the solution for 24 hours before planting them in soil infected with the pathogen that causes spinach wilt. The results were impressive—only about 12% of the spinach plants became infected, compared to much higher rates in untreated crops. Similarly, when pepper seedlings were treated with the same bacteria, the incidence of root rot caused by harmful bacteria dropped to roughly 20% of the level seen in untreated plants.
Researchers are currently expanding their studies to test the effectiveness of this pesticide on other crops and to ensure it is completely safe for human consumption. If these trials go smoothly, the pesticide could be commercially available as early as 2012.
The lead scientist behind the project emphasized that this new pesticide is entirely free of chemical additives, which aligns with growing consumer demand for safer and more sustainable farming practices. However, the production process is labor-intensive, and experts predict that the final product may come with a higher price tag than conventional pesticides. Despite this, the potential benefits for both agriculture and public health make this development an exciting step forward in the field of eco-friendly pest control.
