Study Notes
Pesticide Formulations and Handling
- The active ingredient in a pesticide formulation is essential for pest control.
- Pesticide formulations differ in safety, efficacy, environmental impact, and cost, making careful selection crucial.
- Clogged nozzles and screens are not a primary concern when handling emulsified concentrate pesticides.
- Soluble powders are among the formulations that can dissolve in water.
- Mixing wettable powders and soluble powders poses a risk of inhaling dust.
Application and Mixing Guidelines
- Flowable pesticide formulations must be mixed with water prior to application.
- Emulsifiable concentrates create emulsions when mixed with water, enhancing effectiveness.
- Most bait formulations contain less than 50 percent active ingredient.
- Baits must be placed with extreme caution to prevent access by children, pets, or other non-target species.
- Pesticide manufacturers may not include all necessary adjuvants, often requiring additional mixing.
Fumigants and Pesticide Compatibility
- Fumigants are highly regulated, used in soil, enclosed structures, and containers, targeting a wide range of pests and posing significant hazards.
- Pesticides that cannot be effectively mixed are referred to as incompatible.
- When mixing pesticides, begin with solid formulations rather than liquid ones.
- Adjuvants are necessary for applications on waxy or hairy leaves for better adhesion and efficacy.
- Not all pesticide spray mixtures can include adjuvants; some formulations may not require them.
