- READ ALL DIRECTIONS BEFORE USING.
- MIX PREFAR 4-E WELL BEFORE DILUTING WITH WATER.
- Prefar 4-E mustbe used only for purposes listed on the label. Do not exceed the rates specified on the label. (DO NOT OVERDOSE.)
- USE ON MINERAL SOILSONLY.
- Application of Prefar 4-E to soil that is cold and/or wet for an extended period of time due to rains or poorly drained soil during the germination period may result in reduction of crop stand or yields.
- Combining Prefar 4-Ewith fertilizers or other agricultural chemicals could result in incompatibility, reduced efficacy, or reduced crop safety. It is recommended that the user test the response of combination treatments with other products on a small scale prior to commercial scale use.
- Vary the rate of Prefar 4-E you apply depending on the soil texture. Apply the higher specifiedlabel rates to heavier, fine textured soils. Apply lower rates to lighter, coarse textured soils with lower organic matter.

Mixers, loaders, applicators and other handlers must wear:
- Long-sleeved shirt and long pants
- Chemical resistant gloves such as barrier laminate or Viton > 14 mils
- Shoes plus socks
In addition, a NIOSH-approved dust-mist filtering respirator with MSHA/NIOSH approval number prefix TC-21C or a NIOSH-approved respirator with any N, R, P, or HE filter must be worn by: 1) mixers, loaders,2) persons participating in chemigation, and 3) commercial or for-hire applicators (due to risk from repeated exposures)
Follow manufacturer’sinstructions for cleaning/maintaining PPE. If no such instructions for washables, use detergent and hot water. Keep and wash PPE separately from other laundry
- Engineering Controls
- When handlers use closed systems or enclosed cabs, in a manner that meets the requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides (40CFR 170.240(d)(4-6), the handler PPE requirements may be reduced or modified as specified in the WPS

- Hazards
ENVIRONMENTAL HAZARDS :
- This chemical is toxic to fish and aquatic invertebrates. Do not apply directly to water, or to areas where surface water ispresent or to intertidal areas below the mean high water mark. Do not apply when weather conditions favor drift from the treated area.
- This product is highly toxic to bees exposed to direct treatment or residues on blooming crops or weeds. Do not apply this product or allow it to drift to blooming crops or weeds if bees are visiting the treatment area
- Do not apply directly to water, or to area where water is present or to intertidal areas below the mean high water mark. Do not contaminate water when cleaning equipment or disposing of equipmentwashwaters or rinsate
- This product may impair reproduction in birds if used during the breeding season
PHYSICAL OR CHEMICAL HAZARDS
- Combustible. Do not use, store, pour, or spill near heat or open flame. Keep container closed when not in use.
Storage & Handling
- Storage and Disposal
- Do not contaminate water, food, or feed by storage or disposal.
- PESTICIDE STORAGE:Protect from temperatures below 42° F. At temperatures below 42° F product may crystallize. Dissolve crystals with quiet storage at warm temperatures (75° F). Redissolution rate: 40-48°F (40-60 days); 60° F (1-3 weeks); 70-80° F (1-3 days). Roll container and agitate contents to provide a uniform product prior to use.
- PESTICIDE DISPOSAL:Wastes resulting from the use of this product must be disposed of on site or at an approved waste disposal facility.
- CONTAINER DISPOSAL: For Non-Bulk Plastic Containers:Nonrefillable container. Do not reuse or refill this container. Offer for recycling, if available. Triple rinse container (or equivalent) promptly after emptying. Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank and drain for 10 seconds after the flow begins to drip. Fill the container ¼ full with water and recap. Shake for 10 seconds. Pour rinsate into application equipment or a mix tank or store rinsate for later use or disposal. Drain for 10 seconds after the flow begins to drip. Repeat this procedure two more times. After cleaning, if recycling is not available, puncture and dispose of in a sanitary landfill or by incineration or if allowed by State and local authorities by burning. If burned, stay out of smoke.
- CONTAINER DISPOSAL: For Nonrefillable Bulk Plastic Containers:Nonrefillable container. Do not reuse or refill this container. Offer for recycling, if available. Triple rinse container (or equivalent) promptly after emptying. Triple rinse as follows: Empty the remaining contents into application equipment or a mix tank. Fill the container ¼ full with water. Replace and tighten closures. Tip container on its side and roll it back and forth, ensuring at least one complete revolution,for 30 seconds. Stand the container on its end and tip it back and forth several times. Turn the container over onto its other end and tip it back and forth several times. Empty the rinsate into application equipment or a mix tank or store rinsate for later disposal. Repeat this procedure two more times.
- For Refillable Bulk Containers:Refillable container. Refill this container with pesticide only. Do not reuse this contain for any other purpose. Cleaning the container before final disposal is the responsibility of the person disposing of the container. Cleaning before refilling is the responsibility of the refiller. To clean the container before final disposal, empty the remaining contents from this container into application equipment or mix tank. Fill the container about 10 percent full with water. Agitate vigorously or recirculate water with the pump for 2 minutes. Pour or pump rinsate into application equipment or rinsate collection system. Repeat this rinsing procedure two more times.
- Container Precautions: Before refilling, inspect thoroughly for damage such as cracks, punctures, bulges, dents, abrasions, and damaged or worn threads on closure devices.REFILL ONLY WITH PREFAR 4-E. The contents of this container cannot be completely removed by cleaning. Refilling with materials other than Prefar 4-E will result in contamination and may weaken container. After refilling and before transporting, check for leaks. Do not refill or transport damaged or leaking container.
- SPILL OR LEAK: Small spills can be handled routinely. Use adequate ventilation and wear an air-supplied respirator to prevent inhalation. Wear suitable protective clothing to prevent skin and eye contact. Use the following procedures:
- Spread a suitable absorbent such as clay, sawdust or kitty litter on the spilled material.
- Place sweepings in an appropriate chemical waste container.
- Generously cover the contaminated areas with a common household detergent. Using a stiff brush and small amounts of water, work the detergent into the spill material forming a slurry. Do not splatter on yourself or bystanders and completely avoid skin or eye contact with this material. Brush the slurry into cracks and crevices and allow to stand for 2-3 minutes.
- Spread absorbents on the slurriedliquid and shovel the absorbed material into the container.
- Repeat if necessary.
- Flush the area with water while observing proper environmental considerations
- Seal container and dispose of in approved pesticide landfill.Large spills should be handled according to a predetermined plan. For assistance in developing a plan, contact Gowan Company.
