  1. Greenhouse Safety

  2. Applying Pesticides

  3. Objectives ENABLING OBJECTIVES • Demonstrate safe chemical application methods 01

  4. Objective 1Demonstrate safe chemical application methods

  5. PESTICIDE • Chemicals to destroy pests • Be aware of the environmental consequences to greenhouse employees, crops, and equipment

  6. Pesticide Labels • Acceptable methods of usage, storage, and disposal • Personal protective clothing • Correct use of equipment • Environmental, physical, or chemical hazards and indicated toxicity to certain plants or animals • EPA classification • Safe reentry time • “Keep Out of Reach of Children” • Controls how the product is sold and distributed • If poisoning occurs, doctors refer to the label for treatment data • ESSENTIAL to adhere to label information and directions  

  7. Reading Pesticide Label Activity

  8. Activity:Look Up MDS Sheets on Each Pesticide in the Greenhouse

  9. TOXICITY

  10. Pesticide Toxicity Levels • Each chemical listed on label contributes key ingredients that target pests • Cumulative effect of all chemicals is its toxicity level • Measured in LD (lethal dose) • Based on test mammal populations • LD50 refers to the amount of pesticide required to kill 50% of a test population within 2 weeks • The lower the LD50 value, the higher the toxicity WARNINGS: “Caution” Slightly toxic, LD50= 500-5,000 “Warning” Moderately toxic, LD50=50-500 “Danger - Poison” Most toxic, LD50=0-50

  11. Types of Pesticides LIQUID FORMS OF PESTICIDES DRY FORMS OF PESTICIDES

  12. Pesticide Safety • Must be handled with extreme caution • Potentially lethal to humans and animals • Follow all storage instruction • Store in original containers with labels visible • Keep away from flammable materials • Check for leads or damage • Keep away from food, medicine, and supplies Personal Protection Measures: • Obtain proper education and permits for pesticide use • Use Personal Protective Equipment (PPE) • Goggles, respirator, long sleeves rolled over long rubber gloves, hat, rubber boots, and overalls or coveralls secured with a band over boots.

  13. Guidelines for Applying Pesticides Safely: • Select the safest, least toxic substance possible • Use approved products only forintended purpose • Mix only the amount needed • Apply with extreme caution • Use proper equipment and clothing • Review label carefully • Know and follow proper application procedures
