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.
Test your knowledge on herbicide formulation and application. Learn about active and inert ingredients, different types of herbicide formulations, and the primary site-of-action targeted by herbicides.
