DIRECTIONS FOR USE


• 1,4SIGHT is used as an aerosol to enhance the dormancy of potatoes during storage.
• Applicators and other handlers must wear: long-sleeved shirt, long pants, shoes, socks, protective eyewear (goggles or face shield), and chemical resistant (such as nitrile or butyl) gloves.
• For entry and re-entry into treated areas during application and prior to ventilation or settling of aerosol fog, workers must wear: coveralls over long-sleeved shirt, long pants, shoes plus socks, and chemical resistant (such as nitrile or butyl) gloves; respirator; face-sealing goggles, unless
a full-face respirator is worn; refer to the PRECAUTIONS section for appropriate respirator.
• 1,4SIGHT must not be applied to potatoes in the field.
• 1,4SlGHT may be applied anytime after the potatoes are placed into the storage area.
• 1,4SIGHT is a short term dormancy enhancer which should not adversely affect eventual germination of seed potatoes.
• Do not allow vapors to come in contact with storage areas used for seed potatoes within 60 days of their planting.

APPLICATION TIMING AND RATES


Apply at a rate of 10 to 20 ppm on an active ingredient to potato basis. This is equivalent to:
(i) 0.5 - 1 L of product per 50,348 Kg of potatoes or
(ii) 10 - 20 mL of product per ton of potatoes
The lower rate may be sufficient: for adequately filled stores (< 50% headspace) and storage temperatures between 3 and 8 ºC, storage facilities with little outside ventilation, or facilities that are well sealed. At both rates, re-application needs to take place as required based on regular monitoring and observed movement/development of budding sprouts. The first application of 1,4SIGHT can be made at any time after the potatoes are placed in the storage area, but prior to sprouting. Subsequent re-treatment is only required if visual inspection indicates eye opening.
Allow a minimum of 1 month between treatments. Do not exceed 80 ppm during the storage season.
Response may vary among varieties.
This product when applied to seed potatoes may cause delayed emergence, an increase in stem number, smaller tubers and yield reduction.
1,4-dimethylnapthalene residue levels in potatoes decrease over time. However, the rate of dissipation will vary with storage conditions and among potato varieties. High residue levels may result in undesirable taste characteristics. Residue levels below 0.7 ppm may lead to a loss in efficacy. To minimize the risk of undesirable taste characteristics, residue levels should be monitored to ensure they do not exceed 1 ppm prior to marketing
