OH Pesticide Certification - CORE
A certified applicator may:
a. Apply general use (unclassified) pesticides
b. Apply restricted use pesticides
c. Supervise a non-certified applicator
d. Buy restricted use pesticides
e. All of the above - ANS-E. Certification indicates t=applicators have exhibited competence
to safely use pesticides. Certification is initially obtained through examination. Exams are
given by personnel of the Ohio Department of Agriculture
\A commercial pesticide handling establishment is a:
a. Farm which employs workers
b. Forest which employs workers
c. Business which employs handlers
d. Business which employs crop advisers
e. c and d
f. a and c - ANS-E. A commercial pesticide handling establishment is an establishment other
than an agricultural establishment that employs handlers to apply, mix, load, and transfer
pesticides. Handlers also perform tasks such as cleaning, adjusting, or repairing spray
equipment or performs tasks as a crop advisor
\A common measure of the acute toxicity of pesticides is based upon the:
a. MD80
b. LD50
c. Pesticide consumed in 24 hours
d. Pesticide excreted in 24 hours
e. Both c and d - ANS-B. The acute toxicity of many pesticides is based on an LD50. LD50
stands for lethal dosage of pesticide required to kill 50 percent of the test animals and is
expressed in milligrams of pesticide to kilograms of body weight of the test animals. The
lower the LD50, the more toxic the pesticide is. For example, a chemical with an LD50 of
30mg/kg is more toxic than one with an LD50 of 3000mgkg because it takes less material to
harm an animals
\A farmer has a 5000-gallon tank and is applying pesticide at 20 gallons per acre (GPA). He
wants to apply Lancer 2E at 1 lb. active ingredient per acre and Doubt 25DF at .25 lb. active
ingredient per acre. How much of these two materials should be added to the spray tank for
a 20-acre application?
a. 40 pts. Lancer and 2 lbs. Doubt
b. 10 gallons Lancer and 20 lbs. Doubt
c. 20 gallons Lancer and 20 lbs. Doubt
d. 2 qts. Lancer and 1 lb. Doubt - ANS-B. To obtain the gallons of Lancer needed per acre,
use Formula E/G. (Where E = lbs. of active ingredients recommended per acre, and G = lbs.
active ingredient per gallon.) Therefore, the recommendation of 1 lb. of Lancer per acre
which itself has 2 lbs. active ingredient per gallon equals E/G, or 1 divided by 2. Therefore
1/2 = 1/2 gallon Lancer per acre, 1/2 gallon X 20 acres = 10 gallons of Lancer in the tank.
For Doubt, use the formula E/F (Where E = lbs. active ingredient recommended per acre and
,F = percent active ingredient in the product). Therefore, .25/.25 = 1 lb. of Doubt per acre and
20 lbs. of Doubt would be put in the the spray tank for a 20-acre application
\A farmer has completed an application of pesticides to his soybean field and he has about 5
gallons of spray material left. What should he do with the remaining material?
a. Apply it to his corn field with corn spray
b. Apply it to his garden
c. Dump it in a barrel and forget it
d. Store it in a labeled container and apply it on the next soybean field - ANS-D. This is a
problem that confronts nearly all applicators at one time or another. In all cases, strive to
apply the material to the target so as to avoid the responsibility of handling or storing
hazardous materials. If you are unable to apply the pesticide to the target site, refer to the
label for disposal information.
\A general use (unclassified) pesticide may be used by anyone provided that:
a. The pesticide will control or kill the pest
b. The pesticide can be purchased locally
c. The labeling directions are followed
d. You are a registered pesticide dealer
e. a, c, and d - ANS-C. A general use (unclassified) pesticide is a material not likely to injure
the environment or harm people if labeling directions are followed. Certification is not
required to use "general use" pesticide on your own property
\A pest can be anything that:
a. Competes with humans, domestic animals or desirable plants for food or water
b. Injures humans, animals, desirable plants, structures, or possessions
c. Spreads disease to humans, domestic animals, wildlife, or desirable plants
d. Annoys human or domestic animals
e. All of the above - ANS-E. A pest can be anything that annoys, injures, spreads disease or
competes with desired plants, animals, or humans. Examples of pests include weeds,
insects, fungi, bacteria, mites and nematodes
\A pest-control method should be used only when that method will cost less than the
expected value of a loss from the pest.
a. True
b. False - ANS-A. Even though a pest is present, it may not do very much harm. It could cost
more to control the pest than to allow the damage to occur. The point at which the cost of the
damage exceeds the cost of the control is the "economic threshold."
\A pesticide could be:
a. Bleach
b. Insecticide
c. An insect repellent
d. A herbicide
e. All of the above - ANS-E. A pesticide is any substance or mixture of substances intended
for preventing, destroying, repelling, and/or mitigating any pest, or any substance intended
as a plant regulator, defoliant or desiccant
\A pesticide handler would perform the following tasks:
a. Mix, load, or apply pesticides
b. Handle open pesticide containers
c. Flag
d. Assist with application
, e. All of eh above - ANS-E. Pesticide handlers also would rinse pesticide containers, dispose
of unrinsed containers or repair, clean or adjust contaminated equipment
\A restricted use pesticide is a product that:
a. Only farmers may use
b. Is restricted to commercial applicators
c. Could cause environmental damage or human injury unless it is applied by a certified
applicator
d. Can only be applied by pesticide dealers - ANS-C. All pesticides are classified as either
general use (unclassified) or restricted use. If a pesticide is classified as restricted use, the
pesticide label will have the words "Restricted Use Pesticide" on the top of the front panel of
the label. Classification of pesticides and pesticide uses may be based on the products
poisoning potential, and environmental effect.
\A well should be:
a. Protected form back-siphoning of pesticides
b. Located within 100 feet of the pesticide mixing and loading site
c. Near the pesticide storage facility
d. Cut off below the soil surface and abandoned when no longer useful - ANS-A. Wells
should be at least 100 feet from mixing, loading and pesticide storage, and equipment
clean-up activities. Abandoned wells should be properly protected so that surface water and
contaminants do not run directly into groundwater resources
\Adjuvants - ANS-A chemical added to a pesticide formulation or tank mix to increase its
effectiveness or safety
\Aerosols - ANS-A liquid formulation that generally contains a solvent and a low percentage
of active ingredient. Often packaged as a fogger.
\After obtaining initial certification, private applicators must retake exams every three years
to maintain certification
a. True
b. False - ANS-B. The applicator does not need to retake the exam. In order for an individual
to maintain private certification status, that person must participate in a minimum of three
hours of recertification training. Recertification training must include one hour of core subject
matter and training in each category. Commercial applicators need a minimum of 5 hours of
recertification training
\All people engaged in the production of an agricultural commodity are required to be
certified
a. True
b. False - ANS-B. Growers who use only "general use" products are not required to be
certified. Also employees may work under the supervision of a certified applicator. However,
anyone who handles or applied pesticides is encouraged to become certified
\All pesticides are classified as either
a. Restricted or Toxic use
b. Restricted or Dangerous use
c. Restricted or Homeowner use
d. Restricted use or General Use (unclassified) - ANS-D. Uses of pesticides are classified by
the U.S. EPA as either general (unclassified) or restricted use. Classification of pesticides
and pesticide uses may be based on poisoning potential, type of formulation, way the
pesticide is used, and the potential for harm in the environment. Restricted use pesticides
must be applied by a certified applicator or an individual under the direct supervision of a
certified applicator in accordance to labeling directions.
