DETAILED ANSWERS WITH RATIONALES

What are the uses and characteristics of contact and systemic herbicides?

- ANSWER- Contact herbicides do not move within the plant, they are

sprayed on and only kill the parts of the plant they actually touch.

Systemic herbicides are absorbed through leaves or roots and then

mover or translocate within the treated plant.

What are the effects and uses of plant growth regulators? - ANSWERPlant growth regulators do not kill plants, but are used to increase,

decrease, or change in some fashion the normal growth and or

reproduction of the plant. They may be used to retard plant growth and

reduce the need for other chemical or mechanical management

measures.

Describe the function of inert ingredients: - ANSWER- They do not

possess pesticidial activity but are added to improve application

effectiveness, safety, handling, storage or other characteristics of the

final product.

Why are there different kinds of formulations and what needs to be

considered when selecting one? - ANSWER- The chemistry of the

active ingredients dictate which formulations are possible, so when

selecting a formulation the following should be considered:

effectiveness of the active ingredient, registered use of the active

ingredient, risks to the user, treated site and environment, measurability

of the formulation, characteristics of the formulation and how they will

effect equipment, temperature at which the formulation needs to be

stored ect.

Which formulations applied as liquids do the following: form

suspensions or solutions when diluted, require agitation in the spray tank

after mixing, tend to clog nozzles, are abrasive or may cause sprayer

parts to deteriorate, and are likely to cause phytotoxicity. - ANSWEREmulsifiable concentrates form milky suspensions and require minimal

agitation to keep the suspension uniformly mixed. Water-soluble

concentrates and soluble powders are both true solutions in water and

are non abrasive. Dry Flowables form a suspension in water and require

some agitation in the spray tank, they are abrasive to sprayer

components. Flowables or suspension concentrates are not soluble in

water and they form suspensions that require moderate agitation, but

they seldom clog spray nozzles. Granules are usually applied as a solid

and are nearly always used to treat soil and release the active ingredient

slowly.

What are the health concerns associated with different formulations? -

ANSWER- Emulsifiers are easily absorbed through the skin and contain

a very high concentration of active ingredients. Soluble powders pose

the greatest risk when they are being mixed and loaded when you might

be able to inhale the concentrate powder.

What are the functions of, and precautions regarding the use of

adjuvants? - ANSWER- Adjuvants are chemical additives that are meant

to modify the product's physical properties and/or enhance the pesticide

performance. They serve several purposes such as: wetting agents and

emulsifiers which allow pesticides to mix with water and or coat

treatment surfaces more effectively; spreaders allow pesticides to spread

over the treated surface; stickers increase the adherence of the pesticides

to treated leaves; penetrants which aid in the absorption of a pesticide by

the plant. Adjuvants must not be used indiscriminately because misuse

can lead to injury of a desirable plant, compatibility problems, or

reduced pest control.

What is the most prominent federal pesticide law and which agency

oversees it? - ANSWER- The Federal Insecticide, Fungicide and

Rodenticide Act (FIFRA) and it is overseen by the EPA.

What is involved in pesticide registration and re-registration and the

practical importance of each? - ANSWER- A pesticide must be

registered by the EPA before it can legally be sold or used in the U.S.

The EPA will register the use of a product when test data, submitted by

the manufacturer, show that the intended use of the product will not

create unreasonable risks. Pesticides are re-registered when they are an

older product that has not gone through FIFRA to ensure they do not

pose an unreasonable risk.

Why are some products classified as restricted-use and who may

purchase and apply such products? - ANSWER- If the EPA determines

that the benefits of a pesticide's use will outweigh the risks ONLY when

trained persons use the pesticide, it will classify the pesticide as

Restricted-Use Pesticide (RUP). Only a certified applicator may mix,

load, apply, or direct the use of RUPs.

What should you do when state and federal laws differ? - ANSWERState laws can be more strict than a federal law, but cannot be more

lenient. It is the applicators responsibility to know when the laws differ

and to follow the more strict state standard.

What is the difference between a private applicator, a commercial

applicator for hire and a commercial applicator not for hire? -

ANSWER- Private applicators use or direct the use of pesticides for the

purpose of producing an agricultural commodity and the applications

occur on land owned or rented by you or your employer.

Commercial applicators for hire use or direct the use of pesticides on a

contract basis, meaning you get paid by a third party to perform your

services.

Commercial applicators not for hire use or direct the use of pesticides

only to sites that your or your employer controls and do not contract out

your pesticide application services.

What are the conditions that must be met to register an employee as a

temporary commercial applicator trainee? - ANSWER- The trainee

registration is only valid for 30 days, a trainee may not use a restricteduse pesticide or direct the use of a pesticide, applications of pesticide

must be under direct supervision of a commercial applicator who is

certified and licensed in the appropriate category, trainee must have a

copy of the registration on hand when using a pesticide.

What are the certification and licensing requirements for commercial

applicators? - ANSWER- You must be at least 16 years old, pass an

exam demonstrating knowledge of the proper, safe and legal use of

pesticides, and possess a license allowing them to legally apply
