SS-AGR-255Study Questions for the Certified Pesticide Applicator Examination: Natural Areas Weed Management 1 Ken A. Langeland2The following questions are intended to help prepare you for taking the Natural Areas Weed Management Certified Pesticide Applicator Examination. It should be used along with IFAS publications SP 295 Natural Area Weed Management A Training Manual for Restricted Use Pesticide Applicators and SP 257 Identification & Biology of Non-Native Plants in Floridas Natural Areas which can be obtained from the IFAS Extension Book store by calling 800-226-1764 (local 359-392-1764) or from http://ifasbooks.ufl.edu. For some questions you will need a copy of a Garlon 4 herbicid e label, which can be obtained from http://www.cdms.net/manuf/manuf.asp. Answ ers to all questions can be found in these publications. You will greatly improve your ability to achieve a passing examination score by locating the answers to the study questions and writing them down.1.

Study Questions for the Certifi ed Pesticide Applicator Examinat ion: Natural Areas Weed Management2 Chapter 1 What is the similarity between the terms weed and invasive plant? What is different between the definitions of weed and invasive plant? List five control methods that may be coordina ted into an integrated pest management (IPM) program. Chapter 2 Name three plant lists that have legislative authority. What is the best method to obtain a positive identification on a new weed species and provide a record of its occurrence?

Study Questions for the Certifi ed Pesticide Applicator Examinat ion: Natural Areas Weed Management3 Chapter 3 Relative to solubility, what is the main difference between herbicide active ingredients with polar, i.e. salts of acid herbicides, molecules compared to those with non-polar, i.e. esters, molecules? List two non-polar herbicide active ingredients and five polar herbicide active ingredients. Non-polar (esters) Polar (salts of acids) What is the name of the outer layer of a leaf that herbicide mast pass through to enter the plant and what are three components of this layer, which are barriers to herbicide absorption associated with this layer? Layer Components What is the term that describes the most important factor that affects herbicide uptake from soils? What is the term that is used to describe uptake of herbicides by plant roots?

Study Questions for the Certifi ed Pesticide Applicator Examinat ion: Natural Areas Weed Management4 Draw a cross section of a woody (dicot) plant stem and show the location of the living tissue. List four plant processes that are affected by herbicides (herbicide mode of action). Herbicides with which mode of action require additional record keeping under Florida Pesticide Law (core training)? What is the term used for a herbicide that can be use for broadcast application and kill a target weed and not certain non-target plants that it comes in contact with? List three application methods that can be used to selectively control target vegetation. List five methods to reduce drift. List five factors that adversely affect herbicide activity.

Study Questions for the Certifi ed Pesticide Applicator Examinat ion: Natural Areas Weed Management5 List four ways in which herbicides can disappear from soil. List five ways in which herbicides may be deactivated once absorbed by plants. Chapter 4 List two circumstances under which a broadcast herbicide application may be used. What characteristic do all herbicides that are used for basal bark application have in common? How quickly after felling a tree should herbicide be applied to the stump to optimize control? What special care should be taken to prevent non target damage when applying soil active herbicides? Chapter 5 What must be listed on a herbicide label so that it can be legally applied to a particular site? What state agency should you contacted for legal interpretation of label instructions? What state agency issues permits for control of aquatic plants?

Study Questions for the Certifi ed Pesticide Applicator Examinat ion: Natural Areas Weed Management6 When applying a herbicide to control an invasive plant species on a site that is allowed by Special Local Need registration (SLN), what must the applicator have and where should this be? Consider the following list of herbicide active ingredients as indicated: 2,4-D glyphosate hexazinone imazapyr metsulfuron triclopyr Which are likely to be absorbed by plant roots. List under the appropriate Mode of action: Auxin interference Amino acid (protein) syntheses inhibitor Photosynthesis inhibitor Which are likely to leach: Which have the greatest persistence:

Why is diesel fuel not recommended as a herbicide diluent for use in natural areas? List two types of surfactants and how they modi fy performance of a herbicide solution applied to a leaf surface. List three ways by which the use of colorants can be helpful to a herbicide application. How many ounces of herbicide product are needed to prepare 4 gallons of spray solution if the herbicide label requires mixing 20 gallons of product per 100 gallons of spray solution?
