1,4-dimethylnaphthalene (1,4-DMN), a naturally occurring biocontrol that enhances dormancy, controls sprouting and encourages field-fresh quality in stored potatoes, is scheduled for review and regulatory approval under the United Nation’s Food and Agriculture (FAO)’s Codex Alimentarius.
The review process will take place during 2023, with a maximum residue limit (MRL) expected to be adopted by the Codex Alimentarius Commission (CAC) as soon as mid-2024.
1,4-DMN is a true dormancy enhancer rather than a sprout suppressant. It mimics naturally occurring potato hormones, triggering the production of potato tubers’ own dormancy enhancing enzymes. Sold by 1,4GROUP and DormFresh as 1,4SIGHT for processing and tablestock potatoes and 1,4SEED for seed potatoes, 1,4-DMN is effective at managing sprouting and peeping from storage bin close-up right through shipping.
1,4-DMN is currently approved for application in Canada and the U.S. under each country’s biopesticide registration process. As such, 1,4-DMN does not require an MRL under either the Pest Management Regulatory Agency (PMRA) in Canada or the Environmental Protection Agency (EPA) in the U.S.
