MN Pesticide Applicators Prep
Examination and Correct Answers
(2025-2026) Verified Update.
Describe what areas/sites an applicator with the natural area, forestry, and rights-of-way
certification can treat - Answer Certified to treat vegetation plus emergent vegetation exposed
above water or found in natural areas, forest, and rights-of-way.
Describe the type of work that requires a natural area, forestry, and rights-of-way certification -
Answer Natural areas, managed to protect existing species, or restore native plant
communities to a more natural state
Right of ways, maintain facilities and structures such as power lines and outages to prevent
possible problems which include power outages
Forestry, THIS DOES NOT INCLUDE ABORICULTURE, but is limited to silviculture which the
establishing and managing of forest.
On a drawing, ID different plant types, such as terrestrial, submergent, floating-leaved and
emergent - Answer Emergent plants/vegetation are plants that are rooted in the sediment
with most of its parts into above the waterline
Floating plants are plants rooted in the lake bottom, but leaves and flowers float on the surface.
Submergent vegetation are plants that have stems or leaves growing entirely below the surface
of the water as water levels fluctuate
Terrestrial plants are living or growing on dry land
Using labels, distinguish between herbicide approved for terrestrial vs. aquatic emergent plant
sites of application - Answer READ THE LABEL, see what site the herbicide is allowed to be
applied. Herbicides can be used for either terrestrial, aquatic or both sites. As a Cat. J applicator
you can not apply chemical directly to surface water, but you can apply DEPENDENT OF LABEL to
areas that have temporary surface water like snow or ice.
Identify the areas on a label where you should check for restrictions or special instructions for
aquatic uses - Answer Product Use and Restrictions, species for treatment, and Use sites and
Wetland sites in forest and non-crop Areas
, List three laws, licenses, or permits that you should be aware of when applying pesticides at a
CAT J. - Answer Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)- designed to
protect citizens and the environment from pesticide misuse.
Worker Protection Standard - to protect certain employees from exposure to pesticides .
National Pollutant Discharge Elimination System - controls the permitting of direct discharge of
pollutants into navigable waters.
Noxious Weed Law- identifies plants that are considered harmful to public health, the
environment, public roads, crops, livestock, and other property
list two ecological impacts of invasive, non species - Answer Invasive species/non-native
species - generally have an advantage that allows them to reproduce and spread quickly,
displacing native vegetation and can cause native wildlife depended on the native vegetation for
food and shelter to be displaced.
Identify a situation where you would use an herbicide approved for aquatic uses - Answer If
you are spraying an emergent plants the herbicide must be approved to use for aquatic sights
and approved on the MNDNR list of aquatic applications.
List three potential environmental impacts from the use of pesticide - Answer Surface Water
Groundwater
Non-Target Species
ID two ways to protect water during pesticide applications - Answer If applying near the ware,
leave a buffer area of untreated vegetation between the sprayer area and the water. Use a
pesticide labeled for both terrestrial and aquatic use, don't apply if rainfall will happen during
the day/two hours after application, resist spraying over water
List two ways you can minimize harm from a pesticide application to non-target plants and
animals - Answer Avoid using a surfactant if it adjust the products toxicity level. For example
some surfactants can damage a fishes protective slime layer of fish, making them more
vulnerable to chemical and diseases.
List two ways you can reduce negative impacts on pollinators - Answer Avoid spraying
