17
Q

key pests

A

cause major damages on regular basis

18
Q

secondary pests

A

become a problem when a key pest is controlled or absent

19
Q

occasional pests

A

become troublesome once in awhile because of factors such as life cycle, environmental change, or human activities

20
Q

economic threshold

A

pest population density at which control measures are needed to prevent the pest from reaching economic injury level

21
Q

economic injury level

A

pest population density that causes losses equal to the cost of control measures

22
Q

DANGER-POISON (signal word)

A

product is highly toxic by any route of entry into the body

23
Q

DANGER (signal word)

A

product is highly toxic by at least one route of entry; severe eye and skin irritation

24
Q

WARNING (signal word)

A

product is moderately toxic; moderate eye and skin irritation

25
Q

CAUTION ( signal word )

A

product is slightly toxic; slight eye and skin irritaiton

26
