  1. Management • Control The Nature Conservancy handbook of weed management: http://tncweeds.ucdavis.edu/handbook.html http://tncweeds.ucdavis.edu has lots of useful information including case studies

  2. Management • Control • Chemical control

  3. Management • Control • Chemical control • Chief tool

  4. Management • Control • Chemical control • Chief tool, but often creates other hazards

  5. Management • Control • Chemical control • Chief tool, but often creates other hazards • Evolution of resistance

  6. Management • Control • Chemical control • Chief tool, but often creates other hazards • Evolution of resistance • Herbicide needs to be approved for target species

  7. Management • Control • Chemical control • Chief tool, but often creates other hazards • Evolution of resistance • Herbicide needs to be approved for target species • Often expensive

  8. Management • Control • Chemical control • Chief tool, but often creates other hazards • Evolution of resistance • Herbicide needs to be approved for target species • Often expensive • Public opposition

  9. Management • Control • Chemical control • Chief tool, but often creates other hazards • Evolution of resistance • Herbicide needs to be approved for target species • Often expensive • Public opposition • Many above compounded by need for repeated applications

  10. Management • Control • Chemical control • To spray, or not to spray?

  11. Management • Control • Chemical control • To spray, or not to spray? • Does the “good” outweigh the “bad”?

  12. Management • Control • Chemical control • To spray, or not to spray? • Does the “good” outweigh the “bad”? • How effective is herbicide against targets? • Will herbicide affect non-targets? • Will herbicide use conflict with other management goals/uses? • Will there be adverse environmental impacts? • Is it cost effective?

  13. Management • Control • Chemical control • To spray, or not to spray? • Does the “good” outweigh the “bad”? • Can the herbicide be practically and safely used?

  14. Management • Control • Chemical control • To spray, or not to spray? • Does the “good” outweigh the “bad”? • Can the herbicide be practically and safely used? • Have you read and understood the label? • What are the safety protocols for storing, mixing, transporting, using, disposing of herbicide? • What are federal, state, & local regulations for use of herbicide? • Is specific or general applicator training or permits required? • Is the appropriate protective gear available and practical to use?

  15. Management • Control • Chemical control • Which herbicide to use?

  16. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Based on chemical structure • Mode of action • Similar chemical structure usually similar modes of action, but different structure can also give similar modes of action

  17. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Auxin mimics

  18. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Auxin mimics • Mitosis inhibitors

  19. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Auxin mimics • Mitosis inhibitors • Photosynthesis inhibitors

  20. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Auxin mimics • Mitosis inhibitors • Photosynthesis inhibitors • Amino acid synthesis inhibitors

  21. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Auxin mimics • Mitosis inhibitors • Photosynthesis inhibitors • Amino acid synthesis inhibitors • Lipid synthesis inhibitors

  22. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent

  23. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation

  24. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Ingredients • Active ingredients • Adjuvants • Solvents, carriers, dyes

  25. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Ingredients • Form • Liquid, sprayable • Dry granules, pellets, or dusts

  26. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation

  27. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Movement

  28. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Movement • Immobilization

  29. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Movement • Immobilization • Degradation • Photodegradation • Microbial degradation • Chemical decomposition

  30. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Movement • Immobilization • Degradation • Photodegradation • Microbial degradation • Chemical decomposition • Volatilization

  31. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Toxicity • LD50 / LC50

  32. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Toxicity • LD50 / LC50 • Human toxicity

  33. Management • Control • Chemical control • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Toxicity • LD50 / LC50 • Human toxicity • Adjuvants, impurities, & degradation products

  34. Management • Control • Chemical control • Chief tool, but: • Evolution of resistance • Approved for target species • Expensive • Public opposition • Repeated applications • To spray, or not to spray • Does the “good” outweigh the “bad”? • Can the herbicide be practically and safely used? • Which herbicide to use? • Herbicide families • Mode of action • Pre-emergent vs post-emergent • Formulation • Dissipation • Toxicity
