MN Pesticide Applicators Cat J Exam
Questions and Answers
Describe what areas/sites an applicator with the natural area, forestry, and rights-of-way
certification can treat - -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 - -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 - -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 - -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 - -Product Use and Restrictions, species for treatment, and
Use sites and Wetland sites in forest and non-crop Areas
-Determine the appropriate products to use for the intended site of application - -READ
THE LABEL, look for the information that is related to what you are trying to treat.
-List three laws, licenses, or permits that you should be aware of when applying pesticides
at a CAT J. - -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 - -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 - -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 - -Surface Water
Groundwater
Non-Target Species
-ID two ways to protect water during pesticide applications - -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 - -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 - -Avoid spraying blooming
plants, apply herbicide when bees are not present, leave buffer zones, Spot treat instead of
broadcast spraying
-Describe how the biennial plant life cycle affects an herbicide treatment plan - -Biennial
plants are plants that generally need two growing seasons to complete their life cycle.
First season is when the seed germinates and produce only vegetative growth (Rosette).
Second season the plant will produce flowers and fruits (bolting) then die.
-Name three parts of the plant where herbicide may be applied for plant control - -Leaves-
visible part of the plant, the blade is the main body of the leaf, stipules are small leaf-like
appendages found at the base of the petiole. The petiole transports materials to and from
the leaf. (Primary application target)
Epidermis- The outer protective layer or layers of cells which is covered by a waxy layer.
Can affect the ability of the pesticide to penetrate the plant.
