Study Notes
- Herbicides Formulation: a mixture of active ingredient (a.i.) and inert ingredient
- Active ingredient: chemical causing phytotoxicity and controlling target weeds
- Inert ingredient: additives, diluents, extenders, or adjuvants with no herbicidal activity
- Herbicide formulation: available in dry (granule, pallet, etc.) and liquid (concentrates, emulsifiable, oil soluble, ready-to-use) forms
- AGR 3102: Principles of Weed Science, Week 9 topic: Herbicides - Adjuvants
- Adjuvants: compounds added to herbicide formulations or tank mixes to enhance application, effectiveness, or stability
- Two main functions: 1) improve ease of application, mixing, and handling 2) enhance product efficacy
- Two basic groups: 1) Activator adjuvants: increase herbicide deposition, adhesion, retention, penetration, and absorption into weeds.
