120+ QUESTIONS AND 100% VERIFIED ANSWERS |
GRADED A+ | GUARANTEED PASS!!
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
- answer-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
- answer-E. A commercial pesticide handling establishment is an establishment
other than an agricultural estalbishment 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
- answer-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
- answer-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
- answer-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
- answer-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
- answer-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
- answer-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
- answer-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
- answer-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
- answer-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
- answer-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
- answer-A chemical added to a pesticide formulation or tank mix to increase its
effectiveness or safety
Aerosols
- answer-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
- answer-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
