Bio-control agent for storage set for international approval.

A NATURALLY-occurring bio-control that enhances dormancy, controls spouting 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 of 1,4-dimethylnaphthalene (1,4-DMN), 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 highly effective at managing sprouting and peeping from storage bin close-up right through shipping.
