Soluble
|
Able to be dissolved in another substance
|
|
|
Solution
|
Mixture of substances without chemical change taking place
|
|
|
Solvent
|
Liquid, such as water, kerosene, xylene, or alcohol, that will dissolve pesticide (or other substance) to form solution
|

Substance that contains undissolved particles mixed throughout liquid
|
|
|
Target pest
|
Pest toward which control measures are being directed
|
|
|
ULV (ultra-low volume)
|
Concentrations that approach 100% active ingredient
|
|
|
Volatile
|
Evaporating rapidly; turning easily into a gas or vapor
|
|
|
What is a pesticide formulation?
|
A mixture of active and inert (inactive) ingredients that forms a pesticide product
|
|
|
What is the difference between active and inert ingredients?
|
ACTIVE ingredients are the chemicals that control pests and have toxicity.
INERT ingredients are added to make the product safer, more effective, easier to measure, mix, and apply, and more convenient to handle |
|
|
What are the factors that you should consider when you have a choice of formuations for a pest-control task?
|
1. Right equipment
2. Apply safely 3. Reach the target 4. Stay in place long enough 5. Harm to target site |
|
|
If you had a choice of either a wettable powder or granular pesticide, which would be best if drift were a major concern?
|
Granular pesticide
|
|
|
If you had a choice of either a wettable powder or granular pesticide, which would be best if you needed the pesticide to stay on a surface that is not level, such as foliage?
|
Wettable powder
|
|
|
If you had a choice of either a wettable powder or an emusifiable concentrate, which would be better if you were concerned about harming the treated surface?
|
The wettable powder, because ECs are corrosive and may cause pitting, discoloration, or other damage.
|
|
|
If you had a choice of either a wettable powder or an emusifiable concentrate, which would be better if you were diluting with very hard or alkaline water? |
You would use emusifiable concentrate, wettable powders are difficult to mix in very hard or alkaline water. |
|
|
Why are adjuvants sometimes added to pesticide formulas?
|
To increase effectiveness or safety
|
|
|
What type of adjuvant would be used to reduce drift?
|
Foaming agent, thickener
|
|
|
What type of adjuvant would be used to coat a surface evenly?
|
Spreader
|
|
|
What type of adjuvant would be used for combining two or more pesticides in one application?
|
Compatibility agent
|
|
|
Herbicide
|
Type of pesticide used against weeds
|
|
|
Microbial insecticide
|
Microorganisms or microbes that biologically control insect pests
|
|
|
Avicide
|
Designed to control pest birds
|
|
|
Rodenticide
|
Designed to kill rodents
|
|
|
