1. Name 5 important qualities to consider when choosing a pesticide. -
ANSWER efficacy, persistence, mobility, toxicity, and mode of action
2. What is the difference between selective and non selective herbicides? -
ANSWER a selective herbicide controls some plants and not others (ex.
sethoxydim only controls grasses and not broadleaf)
non selective controls all types of plants.
3. What is the difference between residual and non residual pesticides? -
ANSWER non residual pesticides break down quickly into nontoxic by-
products. a residual pesticide may remain active for weeks, months, or even
years
4. Define pesticide resistance - ANSWER the ability of a pest population
that is repeatedly exposed to a given pesticide to resist and survive its
effects. an insect population, for example, often has "abnormal" members
that can tolerate exposure to insecticide doses that kill "normal" members.
Each time the same MOA is used, the susceptible members die, and the
resistant members survive and breed. in time most of the members will be
resistant to the insecticide.
,5. How can you slow down or limit pesticide resistance? - ANSWER 1.
rotate MOAs
2. use pesticides that target multiple sites in a pest
3. use new or altered pesticides
4. treat alternate generations of pests
5. use non chemical control methods where feasible
6. Explain the difference between the words "label" and "labeling" - ANSWER
The label is the information printed on tor attached to the pesticide
container. labeling includes the label itself, plus all other info recieved from
the manufacturer about the product
7. What is registration of a pesticide - ANSWER the ongoing review of a
registered pesticide to assess the risks and benefits associated with its
labeled uses. the goal of registration is to identify and reduce risks, based
on current scientific knowledge
8. What is a tolerance - ANSWER the max amount of pesticide residue that
may remain on food or reed at harvest or slaughter. tolerance levels are set
by EPA. observing tolerances is crucial in ensuring food safety.
9. When and why may a pesticide product be registered for a special local
need SLN? - ANSWER if a manufacturer wants to register a pesticide for
use only on a regional crop or to manage a localized pest problem. SLN
registrations allow states to expand or limit the uses of federally registered
pesticides within their jurisdictions.
,10.What is a federal Section 3 registration? - ANSWER an EPA registered
product with a label reviewed and approved by that federal agency. Most
pesticides are registered this way. these have an EPA registration number
11.True or false: ALL pesticide products must be registered with EPA. This
agency reviews the labels of ALL pesticide products sold in the US - ANSWER
False. Minimum risk pesticides are exempt from the federal registration
process.
12.Under what conditions may a pesticide be labeled "minimum risk" and thus
be exempt form federal regulations? how do labels of minimum-risk Section
25(b) products differ from those that are EPA registered (section 3)? -
ANSWER EPA has produced a list of minimal risk active and inert
ingredients. to be exempt, all of the active and inert ingredients in a
pesticide product must be on this list.
13.Are minimum risk products exempt from Virginia's state registration
requirements? - ANSWER no. all pesticides that are sold or used in the
Commonwealth of Virginia must be registered with VDACS office of
pesticide services.
14.What are emergency (section 18) exemptions> - ANSWER responses to
pest problems for which no pesticides are registered. section 18 exemptions
allow the sale and use of a certain pesticide for a specific nonregistered
purpose for a specified period. the four types of emergency exemptions are:
specific, quarantine, public health, and crisis.
, 15.What is a restricted use pesticide? - ANSWER RUPs are pesticides that
require special care and handling. the restricted use designation limits the
use of a pesticide product. RUPs are for sale only to properly certified
applicators. only trained persons, or people under their direct supervision,
may handle and apply RUPs.
16.EPA classifies pesticides RUPs for different reasons. Some are highly toxic to
humans. others may cause long-term health effects. still others are
restricted because of an environmental effect such as ground water
pollution.
17.What is the difference between the chemical name, common name, and
trade name? which is the most accurate identify the active ingredient? -
ANSWER chemical name is a complex term that identifies the chemical
components and structure of a pesticide.
18.Common name is a shorter name that EPA recognizes as a substitute for the
chemical name. best identifier.--ex. glyphosate
19.A tradename is used by a chemical company to identify the product--- ex.
round up
20.Name and explain the signal words you see on a pesticide label - ANSWER
DANGER-POISON: skull and cross bones- appears on highly toxic
pesticides. acute illness
DANGER: highly toxic ex. skin irritant
WARNING: moderately toxic
