ANSWERS
◍ what is sanitation?. Answer: use of hygiene practices to manage pests.
◍ what type of mechanical methods could you use to control weeds?.
Answer: weed eaters, shovels, scythes, plows, disks, and mowers
◍ what is physical control and how can it be used to manage certain
pests?. Answer: changing certain environmental conditions such as
water, air movement, temperature, light and humidity. such changes can
control or even eradicate pests.
◍ name 5 important qualities to consider when choosing a pesticide..
Answer: efficacy, persistence, mobility, toxicity, and mode of action
◍ 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.
,◍ what is the difference between residual and non residual pesticides?.
Answer: nonresidual pesticides break down quickly into nontoxic by-
products. a residual pesticide may remain active for weeks, months, or
even years
◍ 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.
◍ 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

may remain on food or reed at harvest or slaughter. tolerance levels are
set by EPA. observing tolerances is crucial in ensuring food safety.
◍ 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.
◍ 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
◍ 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.
◍ under what conditions may a pesticide be labeled "minimum risk" and
