DIRECTIONS FOR USE

It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 

NOTICE 

x 1,4PEEP® is used as an aerosol to eliminate peeps and sprouts and to enhance the 

dormancy of potatoes (and other root and tuber crops, bulb crops, and ornamental flowering 

bulbs) during the storage phase. 

x Applicators and other handlers must wear: coveralls over long-sleeved shirt, long pants, 

shoes, socks, and protective eyewear (goggles or face shield). 

x For reentry 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; face-sealing goggles, unless a full-face 

respirator is worn; and a respirator with an organic vapor-removing cartridge with a pre-filter 

approved for pesticides (MSHA/NIOSH approval number prefix TC-23C) or a canister 

approved for pesticides (MSHA/NIOSH approval number prefix TC-14G) or a NIOSH 

approved respirator with an organic vapor (OV) cartridge or canister with any R, P, or HE 

prefilter. 

x 1,4PEEP® must not be applied to potatoes (or other root and tuber crops, bulb crops, or 

ornamental flowering bulbs) in the field. Apply only from the outside of the treated storage 

areas.

x 1,4PEEP® may be applied anytime after the potatoes (or other root and tuber crops, bulb 

crops, or ornamental flowering bulbs) are placed into the storage area. 

x 1,4PEEP® is a short term dormancy enhancer which should not adversely affect eventual 

germination of seed potatoes (or other crops) held for future planting. 

x Let 60 days elapse before using a treated storage area as a temporary holding area for 

seed potatoes (or other sprouting root, tuber and bulb crops). Air system components 

(including ducts) and building must be thoroughly ventilated before area is used for storage 

of seed potatoes (or other sprouting root, tuber and bulb crops) to prevent dormancy effects. 

x Do not allow vapors to come in contact with storage areas used for seed potatoes (or other 

sprouting root, tuber and bulb crops) within 30 days of their planting.

FORCED AIR DISTRIBUTION METHOD 

1. Prepare aerosol generating equipment. The discharge from the vaporizer should be located 

to provide optimum distribution in the storage area. Take precautions to prevent the spray 

from coming into direct contact with the potatoes (or other root and tuber crops, bulb crops, 

or ornamental flowering bulbs). 

2. Running fans during the application may aid disbursement of vapors, but it is not required. 

3. It is advantageous to keep the storage area closed as long as practical to allow for 

maximum absorption into the potatoes (or other root and tuber crops, bulb crops, or 

ornamental flowering bulbs). 

TREATMENT OF STORAGE AREAS THAT DO NOT HAVE RECIRCULATING AIR 

SYSTEMS

These storage areas are more difficult to treat. Additional steps must be taken to treat these 

storage areas. 

1. Prepare aerosol generating equipment. The discharge from the vaporizer should be located 

to provide optimum distribution in the storage area. Take precautions to prevent the spray 

from coming into direct contact with the potatoes (or other root and tuber crops, bulb crops, 

or ornamental flowering bulbs). 

2. Completely close off the area to be treated. This may include vent doors in the attic and 

walk doors around the perimeter. The large truck doors may need to be sealed to prevent 

excess leakage. 

3. Begin the treatment by following the listed steps: 

 A. Start the aerosol generator. 

 B. Adjust the location of the vaporizer so all the storage area receives an equal amount of 

aerosol fog. It may be necessary to move the vaporizer during the application or make 

the application in multiple phases. For reentry into treated areas during application and 

prior to ventilation or settling of the aerosol fog, workers must wear: coveralls over longsleeved shirt, long pants, shoes plus socks, and chemical resistant (such as nitrile or 

butyl) gloves; face-sealing goggles, unless a full-face respirator is worn; and a respirator 

with an organic vapor-removing cartridge with a pre-filter approved for pesticides 

(MSHA/NIOSH approval number prefix TC-23C) or a canister approved for pesticides 

(MSHA/NIOSH approval number prefix TC-14G) or a NIOSH approved respirator with an 

organic vapor (OV) cartridge or canister with any R, P, or HE prefilter. 

4. For best results wait at least 48 hours before fresh air is introduced into the storage area, 

then return the storage area to “normal” operation. 

5. It is advantageous to keep the storage area closed as long as practical to allow for 

maximum absorption into the potatoes (or other root and tuber crops, bulb crops, or 

ornamental flowering bulbs). 

TREATMENT IN SMALL CONTAINERS 

1. Prepare the application equipment. The discharge from the applicator should be located to 

provide optimum placement in the storage area. Take precautions to prevent the spray from 

coming into direct contact with the potatoes (or other root and tuber crops, bulb crops, or 

ornamental flowering bulbs). 

2. It is advantageous to keep the storage area closed as long as practical to allow for 

maximum absorption into the potatoes (or other root and tuber crops, bulb crops, or 

ornamental flowering bulbs).

Application of 1,4PEEP® can be made any time after the potatoes (or other root and tuber 

crops, bulb crops, or ornamental flowering bulbs) are placed in the storage area. 

Apply at rates of up to 10 pounds of active ingredient per 50,000 lbs (500 cwt), which is 

equivalent to 200 ppm on a product to (potato) (crop) basis. 

While potatoes may be retreated as necessary for effective control, do not exceed the maximum 

application of 800 ppm during the storage season. 

STORAGE AND DISPOSAL 

Do not contaminate water, food or feed by storage or disposal. 

PESTICIDE STORAGE
