Presentation Transcript

  1. Label Comprehension • Goals: To teach: • What IS on the label (and where) • Content • Format • What IS NOT on the label • How to use / follow the label!

  2. Label Comprehension • How to teach about the label using “active learning” methods for field and classroom: • sample PPT + discussion • w/ audience-appropriate interpretive questions… • paper and pencil activities • interpretation / application activities

  3. Label Comprehension • This PPT is NOT “ready to use”! • To convert this “plain vanilla” PPT to an audience-appropriate one, consider: • What do these people do? • What pesticide products do they use? • Do any of these products require special management? • Are any of them similar to other products with different use patterns/requirements?

  4. Label Comprehension • To convert this “plain vanilla” PPT to an audience-appropriate one (continued): • Write (at least one) appropriate/relevant question after each section, on the slide w/ ??? in the title bar. • “Jazz it up” with pictures…?! • Use images of local sites and situations…or • Check out: • http://pesticidepics.ext.vt.edu = pesticidepics.com

  5. Pesticide Labels & Labeling Pat Hipkins Virginia Tech Pesticide Programs

  6. Pesticide Labeling • Background: • Several Types of Registration • federal (Sec. 3) • special local need (SLN or Sec. 24C) • emergency exemption (Sec. 18) • Classification of Pesticides • general use • restricted use

  7. Pesticide Labeling • EPA sets standards (content, format): http://www.epa.gov/oppfead1/labeling/lrm/

  8. Required Information • Name and address of the producer or registrant • Restricted Use Statement (if applicable) • Product Name, Brand or Trademark • Ingredient Statement and net weight or measure of contents • EPA Registration Number and EPA Establishment Number • Signal Word, including Skull & Crossbones, if either are required • "Keep Out Of Reach Of Children" statement • Precautionary Statements, including Hazards to Humans & Domestic Animals and First Aid (Statement of Practical Treatment), Environmental Hazards, and Physical/Chemical Hazards • Storage and Disposal Statements • Directions for Use • Warranty Statement

  9. Mandatory Statements • Relate to actions necessary to: • ensure proper use, and • prevent unreasonable adverse effects on the environment, which is defined by statute. • They may include: • directions for use, • precautions that direct the user to take or avoid specific actions, • specify where, when and how a pesticide may be applied.

  10. Mandatory Statements • Examples of mandatory statements: • “Wear chemical resistant gloves.” • “Do not induce vomiting.” • “Do not apply within 66 feet of wells.” • “Do not apply directly to water.” • “Keep away from heat, sparks and open flame.” • “Do not enter into treated areas for 12 hours.” • “Do not apply when wind speed exceeds 15 mph.”

  11. Advisory Statements • Provide information regarding: • product characteristics, and/or • how to maximize safety and efficacy. • Must NOT conflict with mandatory statements. • May NOT be false or misleading, or otherwise violate statutory or regulatory provisions.

  12. Advisory Statements • Examples of advisory statements: • In the Precautionary Statements section: • “Latex gloves provide the best protection.” • In the Physical and Chemical Hazards section: • “Opening aluminum phosphide containers outdoors or indoors near an exhaust fan or other ventilation ensures that the gas will be rapidly dispersed if the product flashes.”

  13. Advisory Statements • Examples of advisory statements (continued): • In the Directions for Use / Mixing section: • “Apply this product immediately after preparation to ensure that it is in suspension. If application is delayed, agitation to re-mix and ensure proper blending.” • In the Directions for Use / Application section: • “Directing the spray mixture around the base of the cotton plants and using leaf lifters and shields on application equipment will help minimize foliage contact and plant injury.”

  14. Summary: Parts of a Label • Identifying information • Product name, Ingredient statement, Net contents, EPA registration number and establishment number, Use classification (general/restricted; use pattern and site)… • Precautionary Statements • Signal word, child hazard warning, first aid, hazards to humans and domestic animals, environmental hazards, physical or chemical hazards, PPE, engineering controls… • Directions for Use • Ag (WPS) vs. non-ag use requirements, where and how to apply, how much and when to use, how to handle (mix, load, handle, store, and dispose of…) • Conditions of Sale/Limitations of Warranty and Liability (+ name and address of manufacturer, emergency contact info)

  15. Parts of a Label • Identifying Information • Brand Name • Ex: Garlon® 3A • Chemical Name • Ex: 3, 5, 6-trichloro-2-pyridinylozyacetic acid, triethyamine salt • common name • Ex: triclopyr

Parts of a Label • Identifying Information (continued) • Net Contents COMPOSITION • Active Ingredient (% by weight): • triclopyr (3, 5, 6-trichloro-2-pyridinylozyacetic acid, triethyamine salt)…………………………………….44.4% • Inert Ingredients:…………………….…………….…55.6% • Acid equivalent: triclopyr - 31.8% - 3 lb/gallon

  17. ??? • What does the name Garlon®3A tell you about the product?! • Which part of the Ingredient Statement is more useful…and why? • chemical name = 3, 5, 6-trichloro-2-pyridinylozyacetic acid, triethyamine salt • common name = triclopyr
