Mexico approves RNAi-based biological fungicide

The Mexican government has approved the commercial use of a genetically engineered biological fungicide from the U.S. company GreenLight Biosciences. This technology utilizes RNA interference (RNAi) to target specific genes in pests or fungi, aiming to eliminate or reduce their ability to cause infection.

Critics have raised concerns regarding the potential environmental and health impacts of this experimental technique. Because the genetic sequences used to silence specific genes may also be present in beneficial organisms, insects, or plants, there is a risk of unintended damage to biodiversity. In a high-biodiversity nation like Mexico, the rapid approval by Cofepris has been described by some as irresponsible.
