It seems there is some good news ahead for potato producers. 1,4-dimethylnaphthalene (1,4-DMN), 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 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.
