The Active Ingredient of a pesticide usually can not be added to the carrier without modification, so the manufacturer may add Inert Ingredients such as solvents, wetting agents, stickers, etc.
The Active Ingredient of a pesticide usually can not be added to the carrier without modification, so the manufacturer may add other chemicals such as solvents, wetting agents, stickers, etc. This combination is called a FORMULATION
A pesticide Formulation can rarely be used as it was originally made.
A pesticide Formulation can rarely be used as it was originally made. It must be diluted with water, oil, air or other “carriers” so that it can be handled by application equipment and applied evenly to the target area. This combination is called a DILUTION
There are many different types of Formulations: Aerosols (A) Convenient Low Concentration AI BUT, -Expensive -Attractive Nuisances
There are many different types of Formulations: Dusts (D) -Ready to Use -Easily Applied BUT, -High Inhalation Exposure -Highly Prone to Drift -High Profile -Easily Removed from Target
There are many different types of Formulations: Baits -Baits can be strategically placed and removed -Virtually no drift or contamination BUT, -Attractive Nuisance -Secondary Poisoning
There are many different types of Formulations: Granules (G) -Simple Application -Ready to Use -Low Drift BUT, -Not Good For Foliar Applications
There are many different types of Formulations: Ready-To-Use (RTU) -Low Concentration AI -Convenient BUT, -Expensive -Limited Use
There are many different types of Formulations: Emulsifiable Concentrate (EC) -High Concentration AI -Easily Mixed & Stay In Solution -Economical BUT, -Over or Under Mixing Easy -Higher Risk For Exposure -Caustic
There are many different types of Formulations: Flowables (F) -Finely Ground Solid Particles Suspended in a Liquid -Easily Mixed with Moderate Agitation -Low Clog
There are many different types of Formulations: Wettable or Soluble Powders (WP) (SP) -Lower Phytotoxicity than EC -Lower Dermal Exposure Risk -Relatively Low Cost -Easy to Store and Handle BUT, -High Inhalation Exposure -Requires Much Agitation (Will Settle Out) -Abrasive to Equipment
There are many different types of Formulations: Fumigants (F) -Nonselective pesticide -Penetration BUT, -Treatment Area Must Be Enclosed -High Risk

Mixing/Loading Site Should Be: 1. Situated Away From People, Animals, Surface Water & Wells.
Mixing/Loading Site Should Be: Adequately Ventilated
Mixing/Loading Site Should Be: 3. Supplied with: wash water, soap & towels eye wash kit change of clothes spill clean up supplies
Mixing/Loading Site Should Be: An Impervious Surface – which allows applicator to control, contain and recover any spills while minimizing ground and surface water contaminations.

-Mixing and Loading should be performed just before the application is to be made.
-Mixing and Loading should be performed just before the application is to be made. -Check weather before mixing
When Mixing: Do not leave operation unattended!
When Mixing: 2. Use water with pH 4 – 7.
Importance of Correct pH
When Mixing: 3. Consider using Adjuvants (additives that enhance pesticidal activity) - Buffering Agents for pH adjustment - Wetting Agents/Emulsifiers aid in mixing - Anti Drift increases droplet size
When Mixing: Mix no more than you plan to use immediately. This will: - reduce the need to dispose of excess dilutions - minimize potential for surface & groundwater contamination
When Mixing: Triple rinse containers when emptied during mixing/loading. - Add rinsate to tank. - Puncture empty container to prevent reuse.
