What type of mixture has solid particles dispersed, but not dissolved within a liquid?
-Emulsion
-Carrier

Which of the following formulations poses the greater inhalation hazard while mixing and loading?
-Emulsifiable Concentrates
-Soluble Powders
-Flowables
-Water-dispersible Granules

What is the primary benefit of using formulations with water soluble packaging?
-Water soluble packaging helps to limit exposure to pesticide formulations
-Water soluble packaging reduces environmental waste by dissolving the formulation's container into the spray tank
-Water soluble packaging prevents the formulation from getting too wet or dry during storage
-Water soluble packaging contains chemicals that help the formulation mix with water

Which insecticide formulation poses a higher risk to pollinators, including bees, because they can carry the formulation with pollen back to the hive, potentially poisoning the entire colony?
-Wettable Powders
-Water-dispersible Granules
-Microencapsulated
-Emulsifiable Concentrates

Which formulation contains oil solvents that may increase the rate of pesticide absorption through the skin?
-Emulsifiable Concentrates
-Microencapsulated
-Wettable Powders
-Flowables

True or False? You should always consult the pesticide's label before adding any adjuvants to a spray mixture.
True False

What type of adjuvant helps to reduce pesticide inactivation due to the pH of the spray carrier?
-Buffering Agent
-Compatibility Agent
-Penetrant
-Surfactant

What type of adjuvant will help to improve coverage on leaves with thick waxy cuticles?
-Penetrants
-Surfactants
-Compatibility Agents
-Stickers

Which of the following adjuvants is not a spray modifier?
-Surfactant
-Sticker
-Penetrant
-Antifoaming Agent

What is a potential benefit when mixing two or more pesticides in the same spray tank?
-Less soil compaction
-Reduced application costs
-Enhanced control of pests
-All of the above

When problems develop from mixing two or more pesticides together, the pesticide combination is considered to be ____.
-buffered
-effective
-compatible
-incompatible

What is the first step when preparing a tank mixture?
-Add a compatibility agent to the spray tank
-Pre-wet dry suspension formulations into a slurry
-Read each product's label
-Fill the spray tank 1/4 to 1/2 full with carrier

Who is responsible for a failed tank mixture?
-The pesticide manufacturers, because they didn't print warnings on the pesticide labels
-The pesticide manufacturers, even though they prohibited the mixture on the pesticide labels
-The applicator, even when the product labels did not specifically prohibit or provide guidance on the tank mixture
-The pesticide dealer, because they didn't warn me when i purchased the pesticides

When mixing and loading a spray tank, when should you add water-dispersible granule formulations?
-After adding any utility agents
-Before adding any carrier to the spray tank
-After any flowable formulations
-Add them according to the mixing order specified on the label

What type of pesticide would be ideal for controlling broadleaf weeds in a home lawn?
-Selective surfactant
-Non-selective surfactant
-Selective herbicide
-Non-selective herbicide

True or False? Most insecticides are considered to be selective.
True False

-Selective
-Contact
-Nonselective
-Systemic

What type of pesticide offers protection from within the treated plant or animal?
-Nonselective
-Contact
-Systemic
-Selective

Which of the following adjuvant types would help improve pest control when using a contact pesticide?

-Drift-reduction adjuvants
-Penetrants
-Stickers

True or False? The metabolites, or breakdown products, that remain in the environment after a pesticide application are safe and never hazardous to the environment.
True False

How long should a grower wait before harvesting a food crop that was recently treated with a pesticide?
-Wait until a laboratory test indicates that the pesticide residues are below the legal tolerance
-The grower can harvest the crop as soon as the sprays have dried
-At minimum, the grower must follow the preharvest interval specified on the label
-The grower can harvest after at least 1 inch of rain or irrigation has rinsed the residues from the crop
