OH Pesticide Certification – CORE Exam |136
Questions and Answers
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 - -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
-One requirement for effective pest control is:
a. Identification of the pest to be controlled
b. New spray equipment
c. Using more than the recommended dosage
d. Spraying only the field margin - -A. Identifying the pest is the first step. Additionally, it is
necessary to know what control methods are available; evaluate the benefits and risks of
each method or combination of methods; choose the methods that are most effective and
will cause the least harm to people and the environment; use each method correctly; and
observe local, state, and federal regulations that apply to the situation.
-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 - -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."
-Successful pest control is based on the ability to:
a. Eradicate all pests
b. Use pesticides whenever pests are identified
c. Contaminate the environment
d. None of the above - -D. The best answer should be to: 1) keep pest damage to a
minimum by choosing an appropriate combination of control methods, 2) recognize when
direct action is necessary, and 3) endanger the environment as little as possible
-Which of the following is NOT a pest control goal?
a. Prevention - keeping a pest from becoming a problem
b. Suppression - reducing pest numbers to an acceptable level
c. Eradication - destroying an entire pest population
d. All of the above are possible goals - -D. Prevention and suppression are common goals.
Eradication is a difficult goal to achieve, especially in outdoor areas, but may be attempted
,when a foreign pest has been introduced into an area (e.g. gypsy moth, Mediterranean fruit
fly, etc.). Eradication is a more common goal in indoor areas.
-The strategy of combining pest control tactics into a single plan to reduce pests and their
damage to an acceptable level is called:
a. Holistic Resource Management Plan
b. Biological Control
c. Best Management Practices
d. Integrated Pest Management - -D. Biological control is a tactic of Integrated Pest
Management (IPM). IPM is one component of a holistic resource management plan and is
an example of a Best Management Practice.
-When the level of a pest population reaches the stage where pest control action should be
taken, you are at the:
a. Scouting stage
b. Monitoring stage
c. Threshold stage
d. Pesticide application stage - -C. Thresholds maybe based on aesthetic, health, or
economic considerations. Action thresholds have been determined for many pests.
-Which of the following is NOT an example of a control tactic?
a. Pesticide resistance - the ability of a pest to resist pesticide control measures
b. Biological control - using natural predators to control pests
c. Cultural controls - such as crop rotation, date of planting, cultivation, etc.
d. Chemical control - the use of pesticides - -A. Do not confuse pest resistance with host
resistance. Some plants and animals resist pests better than others
-The ability of a pest to resist or avoid poisoning from a pesticide even when it has been
properly applied is called:
a. Efficacy
b. Pesticide resistance
c. Dormancy
d. Antagonism - -B. Each time a pesticide is used, it selectively kills the most susceptible
pests. Some pests are able to withstand its effects. These pests may be able to pass along
this trait to their offspring. Continued use of the same pesticide may allow the resistant
offspring to multiply. This phenomenon is known as pesticide resistance.
-What is pesticide labeling?
a. A sticker stating the price of the product
b. A piece of paper containing product name and promotional information
c. Rebate/Guarantee information
d. None of the above
e. All of the above - -D. Pesticide labeling is all the information received from the
manufacture about a pesticide product. It contains the information on how to use the
product. It should emphasize that adherence to pesticide labeling directions almost
, eliminates personal, personnel, and environmental contamination. It is a violation of state
and federal law to use a pesticide inconsistent with its labeling.
-What is a pesticide label?
a. Information attached to the pesticide container
b. Material safety data sheets
c. An informational brochure
d. All of the above - -The pesticide label in the information attached to the pesticide
container and it is a part of pesticide labeling. To correctly use a pesticide, applicators must
have and comply with pesticide labeling directives.
-It is a violation of the Ohio pesticide law and/or FIFRA to:
a. Use a pesticide on a crop not listed on the label
b. Operate faulty or unsafe spraying equipment
c. Use a pesticide at a higher concentration than is stated on the label
d. All of the above are correct
e. Only a and c are correct - -D. It is in violation of state and federal law to use a pesticide
inconsistent with its labeling directions. Pesticides can be tank mixed with other pesticides
as long as both pesticides can be used on the plants, animals or sites listed in the labeling
directions. Pesticides can be mixed with fertilizer if allowed by label directions. Also, you
may apply a pesticide against a target pest not listed on the label, provided the crop, animal
and site are on the label.
-Before a pesticide can be sold or used in the United States, it must be:
a. Economical to the applicator
b. Approved by the FDA
c. Registered by the U.S. EPA
d. Registered by the USDA - -C. U.S. EPA approves the registration and intended use of each
product. There are 3 major types of registrations, (1) Federal registrations, (by far the most
common) (2) special local needs regulations, and (3) emergency exceptions. The U.S. EPA
also approves labeling directions concerning the safe handling and use of the pesticide.
-Parts of a pesticide labeling include the following:
a. Ingredient statement
b. Signal words and symbols
c. Precautionary statements
d. Storage and disposal directions
e. All of the above - -E. There are many different parts to pesticide labeling. Labeling will
give information on how to use, apply and store the product in addition to information on
treatment for poisoning cases, environmental concerns, active ingredients, inert
ingredients, net contents, name of the manufacturer, endangered species,and personal
protective equipment. There will also appear on some labels, worker protection standard
statements as well as other statements pertaining to situational factors of the particular
pesticide.
-Most pesticides consist of what two chemical components?
