Class4 Insecticides&Fungicides

  1. 1. Insecticides and Fungicides For Ornamentals Commercial Pesticide Applicator Exam Laura Pottorff, Colorado State University, Adams County
  2. 2. Insecticides Can be classified in a variety of ways – Insecticide class • similar chemical make up or family – Mode of action (how does the insecticide work on the pest?) • Stomach poisons • Contact • Systemic • cholinesterase inhibitor
  3. 3. Resistance management When applying insecticides, always focus on resistance management. Do not rely on one insecticide, combination of insecticides or related insecticide classes. Make 2 or 3 applications of an insecticide in sequence, then rotate to another class. Try to avoid applying the same insecticide to more than one generation of the pest.
  4. 4. Insecticides by Class Benzoylurea (acts on the larval stages by inhibiting or blocking the synthesis of chitin.) – Diflubenzuron • Adept
  5. 5. Insecticides by Class – Bacillus thuringiensis- Biological -any biological derived from bacteria agent that adversely affects pest • Dipel species. • Gnatrol – Azidirachtin- derived from – Cinnamaldehyde neem tree (Disrupts molting) • Cinnamite • Azatin XL – Spinosad (postsynaptic acetylcholine mimic) • Ornazin – Beauvaria bassiana - • Conserve derived from fungus – Pyrethrin -derived from chrysanthemum (paralyzes) • Naturalis T& O • Botanigard • Pyrethrum TR
  6. 6. Insecticides by Class Bio-Rational-Biological pesticides, includes pest control agents and chemical analogues of naturally occurring biochemicals (pheremones, insect growth regulators, etc.) – IGR (insect growth regulator) • Stop larvae from maturing • Safe – kinoprene (Enstar 2) – methoprene – phenoxycarb (Precision) – halofenizide (Mach-2
  7. 7. Insecticides by Class – Fenoxycarb Carbamate • Preclude TR (Cholinesterase • Pecision IGR inhibitors) – Methiocarb – Bendiocarb • Mesurol • Closure • Dycarb – Carbaryl • Sevin
  8. 8. Insecticides by Class Carboximide – Hydrazine • Floramite
  9. 9. Insecticides by Class Chloronicotinyl or Nicotinoids (Postsynaptic acetylcholine mimics) – Imidacloprid • Merit • Marathon
  10. 10. Insecticides by Class Dracylhydrazine – Tebufenozide • Confirm T/O
  11. 11. Insecticides by Class Glycoside or Avermectins (GABA blocker) – Abamectin • Avid – Ivermectin – Emamectin
  12. 12. Insecticides by Class Oils- (Clog respiratory openings) – Clarified Hydrophobic Extract of Neem Oil • Triact 70 – Paraffinic Oil • SunSpray Ultra-Fine Spray Oil
  13. 13. Insecticides by Class Organo Chlorines (GABA blockers) – Dicofol • Kelthane – Endosulfan • Thiodan
  14. 14. Insecticides by Class – Diazinon Organophosphate • KnozOut GH (Cholinesterase • PT 1500 KnoxOut inhibitors) • Diazinon – Acephate – Malathion • Address • Orthene TT&O • Pinpoint • 1300 Orthene TR
  15. 15. Insecticides by Class Organtin (acaracide and fungicide) – Fenbutatin-oxide (inibition of oxidative phsophorylation at the site of dinitrophenol uncoupling) • Vendex
  16. 16. Insecticides by Class – Phenoxypyrazole • Fenpyroximate – Akari
  17. 17. Insecticides by Class • Cyfluthrin Pyrethroid (Axonic – Decathon poisons - Sodium channel • Deltamethrin blockers) – Delta Gard – Synthetic chemicals related • Fenpropathin to the botanical pyrethrins – Tame – very toxic to insects at low • Fluvalinate doses – Mavrik – fast knockdown • lambda-Cyhalothrin • Bifenthrin – Scimitar • Permetrhin – Talstar – PT 1800 Attain – Astro
  18. 18. Insecticides by Class Pyridazinone (Inhibits mitochondrial electron transport) – Contact insecticide • Pyridaben – Sanmite
  19. 19. Insecticides by Class Pyridine – Pyriproxyfen • Distance – Pymetrozine • Endeavor
  20. 20. Insecticides by Class Pyrroles (uncouples oxidative phosphorylation) – Contact and stomach poison • Chlorfeapyr – Pylon – Alert
  21. 21. Insecticides by Class Soaps (disrupts cuticle,water rapidly penetrates insect spriacles, reducing oxygen availability. “They drown”.) – Potassium salts or fatty acids • Insecticidal soap 49.52 CF • M-Pede
  22. 22. Insecticides by Class Tetrazine – Clofentezine • Ovation
  23. 23. Insecticides by Class Triazine – Cyromazine • Citation
  24. 24. Fungicides Fungicidal action is usually expressed in one of two ways – inhibition of spore germination – inhibition of fungus growth All fungicides are metabolic inhibitors – they block some vital metabolic process
  25. 25. Classification of Fungicides Inorganic (contain no carbon) – Low mammalian toxicity – Historical uses – Can cause phytotoxicity – Low residual
  26. 26. Classification of Fungicides Synthetic organics (contain carbon) – Highly selective – Residual – Low use rates – Most have low toxicity to mammals and environment
  27. 27. Resistance management for fungicides Rotation of fungicides is an additional strategy against resistance development. To rotate from one product to another does not achieve the goal, rather one must rotate from class and mode of action to successfully fight the potential of resistance development.
