Idaho Code),
means:

B. Pesticides
C. Organic soil amendments
D. A and B above - correct answer-D. A and B above
Which of the following is considered chemigation?
A. Application of a chemical into a pond to kill mosquito larvae
B. Application of fertilizer through a hose-end sprayer
C. Application of a chemical into irrigation water applied to land, crops or plants
D. Application of insecticides through use of a self-contained mosquito misting system -
correct answer-C. Application of a chemical into irrigation water applied to land, crops or
plants
Which of the following is NOT required under Idaho Pesticide and Chemigation Law?
A. Chemigation sites must be listed on the application for a chemigation license.
B. The chemigator must certify that all chemigation equipment meets ISDA requirements.
C. Licensed chemigators must recertify every 2 years.
D. Chemigators must have the chemigation (CH) and the restricted use (RU) categories on
their applicator license before they can chemigate. - correct answer-D. Chemigators must
have the chemigation (CH) and the restricted use (RU) categories on their
applicator license before they can chemigate.
All pesticide applications, including those made through injection into irrigation water, fall
under the
Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). (True or False) - correct
answer-True
Which of the following is a TRUE statement?
A. Even though a pesticide does not address chemigation on the label it is ok to inject the
product into irrigation water.
B. If an agricultural pesticide is approved for chemigation use, it will list the equipment
required to be installed on the irrigation system.
C. Herbicides are not pesticides so do not fall under chemigation laws and rules or FIFRA.
D. All pesticide labels allow the use of any type of irrigation system for chemigation. - correct
answer-B. If an agricultural pesticide is approved for chemigation use, it will list the
equipment required to be installed on the irrigation system.
, The most significant risk associated with chemigation is:
A. Off-target drift of the chemical being applied
B. Over application of the chemical being applied
C. Potential contamination of the water supply
D. Under application of the chemical being applied - correct answer-C. Potential
contamination of the water supply
Advantages of injection of chemicals into irrigation water as opposed to aerial or ground
application are:
A. Chemigation provides a means of incorporation of the chemical to a prescribed depth and
provides moisture for chemical activation.
B. Chemigation allows application of chemicals even when the field is too wet for ground
equipment or weather conditions prohibit other methods of application.
C. Chemigation may reduce applicator exposure to chemicals when done properly.
D. All of the above - correct answer-D. All of the above
Disadvantages of chemigation include which of the following?
A. Irrigation systems cause more mechanical damage to the crop than sprayers and tractors.
B. In fields prone to soil compaction chemigation increases the total area of compaction.
C. Chemigation typically increases application time compared to conventional methods of
application.
D. During windy conditions off-target drift is more likely to occur than through application by
conventional means (ground or aerial applications). - correct answer-C. Chemigation
typically increases application time compared to conventional methods of application.
Before making the decision to chemigate the chemigator should:
A. Assess irrigation water runoff potential.
B. Apply a soil adjuvant.
C. Assure the pesticide to be applied is labeled for application through irrigation systems.
D. A and C above - correct answer-D. A and C above
The chemigator must list all chemigation sites on his chemigation license application and
certify the
sites are in compliance with ISDA chemigation laws and rules. (True or False) - correct
answer-True
One of the disadvantages of chemigation using furrow, drip/trickle and flood irrigation
systems as
compared to sprinkler systems is:
A. Too much water is applied during chemigation.
B. They do not accommodate foliar applications.
C. Most pesticide labels do not allow chemigation through these types of systems.
