1,4SIT

Technological Control of Potato Tuber Dormancy

The core of 1,4SIGHT by DormFresh Limited is the active ingredient 1,4-dimethylnaphthalene (1,4-DMN). This is a natural hormone naturally synthesized by potatoes to regulate their dormancy period. Unlike aggressive sprout inhibitors based on chlorpropham, 1,4-DMN functions as a precise biological 'switch'.

Technically, the product is a suspension concentrate optimized for uniform distribution within vegetable storage facilities. Its mechanism of action relies on decelerating metabolic processes within tuber tissues. When introduced into the storage ventilation system, 1,4-dimethylnaphthalene transitions into a gaseous state, penetrating deep into the potato pile. This is critical for preventing weight loss and maintaining the visual appeal of the produce for extended periods (up to 6-8 months).

Practical Application Features

• Efficacy at Higher Temperatures: Unlike many conventional inhibitors, 1,4SIGHT maintains activity at storage temperatures above +5°C, significantly reducing cooling energy costs.
• Quality Control: The product not only prevents sprouting but also aids in suberization, helping to heal minor skin abrasions caused during harvest, thereby reducing pathogen risk.
• Application Rate: The dosage of up to 1.00 L/ton is calibrated to create the necessary concentration of the active substance within the inter-tuber space.

It is important to note that 1,4SIGHT falls under hazard class 2, requiring strict adherence to protocols for forced ventilation systems. The technical advantage of this product lies in the absence of chemical residues that interfere with downstream processing, such as chip or fry manufacturing, establishing it as the 'gold standard' for exporters and professional processors.
