VA PESTICIDE Exam Questions AND Correct Answers
- ✔✔
1 gallon water = _ Lb - ✔✔8.34 Lb
1 Pound = _ Oz - ✔✔16 Ounces
Active Ingredient - ✔✔Chemicals in products that affect
or control target pest.
Acute Toxicity - ✔✔Measure of harm caused by a single
pesticide exposure LD50 and LC50 are common
indicators of the degree of acute toxicity. Acute effects
can be measured more accurately than delayed effects.
Adherence to Label - ✔✔Label is legal agreement
between EPA, Manufacturer and User
,Adjuvant - ✔✔Substance added to a pesticide
formulation to increase it effectiveness or safety ex.
emulsifier or wetting agent
Adjuvants - ✔✔Aid pesticide but have no pesticidical
activity alone. Use to customize product. EPA does not
register them and there are no standards. Many
different types.
Adsorption - ✔✔Process of adhesion; coating a particle
or binding something to a surface
Aerosols (A) - ✔✔Low active ingredient and are tin two
types:
1.Ready to use- sold in pressurized container. Pros-
convenient, Cons: limited and difficult use
2. Those made for electric or gas powdered aerosol
generators that release formulated product as smoke or
fog. Pros- Easy to fill entire space Cons- May require
respiratory protection and highly specialized
equipment. Spills difficult
,Agriculture Use Requirements - ✔✔Products with uses
covered by the EPA Worker Protection Standard have
separate section with direction for uses in agricultural
applications. Section of Label with specific instructions
for particular use includes: Restricted entry intervals
REI, Notification of treated areas, and PPE
Air-Purifying Respirator - ✔✔Removes particulates and
toxic vapors. Traps and removes contaminants from
surrounding atmosphere using cartridge, canister, or
particulate filer. Sufficient in most scenarios but not in
event of oxygen supply less than 19.5% by volume or
extremely high gas concentration.
Alkaline - ✔✔Opposite of acidic pH greater than 7
Allergic Effects - ✔✔harmful effects that some
experience when exposed to pesticides that other do
not. Reactions do not occur on first exposure but
usually after second or third as on first exposure body
develops a repelling response to this chemical. Process
, is called sensitization and substance that people
become allergic to is called sensitizer. Effects include:
-systemic reactions including asthma or life threatening
shock
-skin, eyes and nose irritation
Animal Systemics - ✔✔Absorbed by, enter the tissues
and move within treated animal. Can be applied
externally and orally to control fleas and other external
or internal parasites.
Annuals - ✔✔-Live 1 yr or less
-Germinate from seed, grow, flower, set seed and die
within 12 months
-Summer annuals germinate in spring or summer and
flower in later summer or early fall
-Crabgrass, Russian thistle
-Winter annuals germinate in late summer, fall, or
winter and flower in the spring
