PRECAUTIONARY STATEMENTS

HAZARDS TO HUMANS AND DOMESTIC ANIMALS:

This product contains methanol and may be toxic to humans 

and domestic animals when not used in accordance with the 

product label.

DANGER – POISON - Methanol may cause blindness. 

Fatal if swallowed, absorbed through skin, or inhaled. 

Corrosive. Causes irreversible eye damage and skin burns. 

Prolonged or frequently repeated skin contact may cause 

allergic reactions in some individuals. Do not get in eyes, 

on skin, or on clothing. Do not breathe vapor. For handling 

activities, use either a respirator with an organic-vaporremoving cartridge with a prefilter approved for pesticides 

(MSHA/NIOSH approval number prefix TC-23C), or a 

canister approved for pesticides (MSHA/NIOSH approval 

prefix TC-14G), or a NIOSH approved respirator with an 

organic vapor (OV) cartridge or canister with any N, R, P, or 

HE prefilter. Wear coveralls worn over long-sleeved shirt 

and long pants, socks, chemical resistant footwear, 

chemical-resistant (such as nitrile or butyl) gloves, goggles 

and face shield. Wash thoroughly with soap and water after 

handling and before eating, drinking, chewing gum, using 

tobacco, or using the toilet. Remove contaminated clothing 

and wash before reuse.

Personal Protective Equipment (PPE): Applicators 

and other handlers must wear coveralls worn over longsleeved shirt and long pants, socks, chemical-resistant 

footwear, chemical-resistant gloves, goggles, face shield 

and respirator. Follow the manufacturer’s instructions for 

cleaning/maintaining PPE. If no such instructions for 

washables, use detergent and hot water. Keep and wash 

PPE separately from other laundry.

User Safety Recommendations:

Users should wash before eating, drinking, using tobacco, or 

using the toilet. Users should remove clothing/PPE 

immediately if pesticide gets inside. Then wash thoroughly 

and put on clean clothing. Users should remove PPE 

immediately after handling this product. Wash outside of 

gloves before removing. As soon as possible, wash 

thoroughly and change into clean clothing.

ENVIRONMENTAL HAZARDS - This product contains 

methanol and may be toxic to fish and aquatic invertebrates. 

Due to the method of application (metering of a relatively 

small amount of product into a stream at a constant rate),

and that methanol will be rapidly diluted below the 

concentration where adverse effects are likely to occur, the 

area that is likely to be directly affected will be in a localized 

area near the point of application.

PHYSICAL OR CHEMICAL HAZARDS – Flammable. 

Keep away from fire, sparks, and heated surfaces. 

SPILLS: Scoop up with a non-sparking tool, then place into 

a suitable container for disposal. Use water spray to 

disperse vapors. Remove all sources of ignition. Absorb 

spill using an absorbent, non-combustible material such as 

earth, sand, or vermiculite.

DIRECTIONS FOR USE: It is a violation of U.S. law to use this 

product in the U.S. in a manner inconsistent with its U.S. labeling. 

The labeling must be in possession of the user at the time of 

application.

Directions for Mixing and Application: Male Sea Lamprey Mating

Pheromone is applied during the sea lamprey migratory and 

spawning season. Male Sea Lamprey Mating Pheromone is applied 

directly to waters near the upstream extent of the reach where 

spawning-phase sea lampreys are present. Applications are made in 

conjunction with trapping systems into which spawning-phase male 

and female sea lampreys are drawn. Each vial (container) of Male 

Sea Lamprey Mating Pheromone, prior to dilution and before 

application, will contain a stock solution created by adding 5 ml of 

methanol + 5 ml of deionized water + 0.10 g of 3-ketopetromyzonol24-sulfate, ammonium salt. Measure stream discharge at the 

application site and calculate the amount of Male Sea Lamprey 

Mating Pheromone required to achieve a concentration between 1 X 

10-11 and 1 X 10-13 M (4.72 to 0.0472 ppt) during the low light period 

(sunset to sunrise). Premix Male Sea Lamprey Mating Pheromone 

with water from the river and pump into the river at a rate that will 

maintain the desired concentration. Verify concentration in the 

stream with an LC/MS (Liquid Chromatography/Mass Spectroscopy) 

method using a deuterated internal standard to calibrate the 

ionization of 3kPZS LC/MS/MS. Adjust application rate as stream 

discharge changes to maintain the desired concentration.

Aerial applications of this product are prohibited.

STORAGE AND DISPOSAL: Do not contaminate water, food or

feed by storage and disposal.

PESTICIDE STORAGE: Store in an area where spills or leakage of 

the material can be contained. Store in a cool, dry, well-ventilated 

place away from sources of ignition and incompatible substances.

PESTICIDE DISPOSAL: Biochemical pesticide wastes are acutely 

hazardous. Improper disposal of excess pesticide, spray mixture, or 

rinsate is a violation of Federal Law. If these wastes cannot be 

disposed of by use according to label instructions, contact your State 

Pesticide or Environmental Control Agency, or the Hazardous Waste 

Representative at the nearest EPA Regional Office for guidance.

CONTAINER DISPOSAL: Nonrefillable container. Do not reuse or 

refill this container. 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 1⁄4 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. Offer for recycling if available or 

puncture and dispose in sanitary landfill, or by other procedures 

approved by state and local authorities. If rinsate cannot be used, 

follow pesticide disposal instructions. If not triple rinsed, these 

containers are acute hazardous wastes and must be disposed in 

accordance with local, state and federal regulations.
