Soybeans treated with the insect-control solution now approved for export

Schaumburg, IL, MARCH 21, 2023—The Codex Committee on Pesticide Residues (CCPR) has approved (S)-methoprene, the active ingredient and insect growth regulator used in Diacon® IGR from Central Life Sciences, for use on soybeans. This Maximum Residue Level (MRL) now allows the exporting of soybeans that have been treated post-harvest with Diacon® IGR for the control of stored-grain insects such as Indian meal moths, red flour beetles and confused flour beetles.

“Securing this approval will open up more international market opportunities for soybean exporters looking to protect their post-harvest commodity with Diacon IGR,” said Nancy Stratinsky, senior business manager for the specialty agriculture division of Central Life Sciences. “We are committed to delivering solutions that protect the stored commodities from profit-robbing insects, and we are excited to further expand the uses of our industry-leading lineup.”

Adding Diacon® IGR to incoming soybeans can protect them from insect-related contamination and damage, preserving their quality and helping to ensure profits are not impacted. This is a major consideration for those exporting soybeans internationally. In addition to treating raw commodities, Diacon® IGR may also be used in processing facilities as a fogging concentrate or surface spray for the treatment of insect pests.

Diacon® IGR is an insect growth regulator that interrupts the life cycle of stored product insects, preventing them from reaching maturity or reproducing to deliver long-term protection. Diacon® IGR is approved for use on all grains, spices, feeds and seeds, including commodities for human and animal consumption. CODEX approval is significant to allow countries to import Diacon® IGR–treated soybeans, however not all countries accept CODEX MRLs, so please check with the country of export to determine if CODEX MRLs are accepted.
