1

The component of a pesticide formulation that controls the pest is the ___________ Ingredient.

ACTIVE

2

(True or False) Careful pesticide selection is important because pesticide formulations vary in their safety to the user, environment, and crop to be treated; efficacy and cost.

TRUE

3

Which of the following is NOT a concern when handling an emulsifiable concentrate pesticide?
a. high phytotoxicity hazard
b. may be easily absorbed through human and animal skin
c. clogged nozzles and screens

C (It dissolves fully, so it would NOT clog nozzles or screens).

4

Which of the following formulations dissolve in water?
a. flowable
b. water dispersible granules
c. soluble powders

C

5

(True or False) Breathing dust is a potential hazard associated with the mixing of wettable powders and soluble powders.

TRUE

6

Which of the following pesticide formulations must be mixed with water before being used by the applicator?
a. flowables
b. granules
c. dust

A

7

(True or False) When added to water emulsifiable concentrates for emulsions.

TRUE

8

(True or False) Most bait formulations have 50% or more active ingredient.

FALSE

9

(True or False) Extreme care must be exercised when placing baits to make them inaccessible to children, pets, and other non-target species.

TRUE

10

(True or False) All pesticide manufacturers include all the necessary adjuvants, thus you do NOT need to add them when mixing a spray tank load.

FALSE

11

Two or more pesticides that cannot be effectively mixed together are said to be_____________.

INCOMPATABLE

12

(True or False) When adding two or more pesticides into a spray tank, always add the liquid formulations first.

FALSE

13

Adjuvants are often required when making applications to leaves that are __________ or ___________.

WAXY OR HAIRY

14

(True or False) Adjuvants can be added to any pesticide spray mixture.

A. Rodenticides and Eradicants
B. Dessicants and Defoliants
C. Eradicants and Organics
D. Systemics and Selectives
E. Insecticides and Fungicides

B

16

Coverage is important in a contact type herbicide because:
A. The pesticide must contact the target pest in sufficient quantity to be effective.
B. Small amounts of pesticides that contact the target pest may not be sufficient to control the pest.
C. Contact herbicides do not translocate.
D. All of the above.

D

17

(True or False)
Wood preservative chemicals are often practically non-toxic and therefore applicators need very little protective clothing or regulation.

B. Are fumigant pesticides
C. Are non-fumigant pesticides
D. All of the above

D

22

Protectant fungicides often must be applied repeatedly during a fungal disease period because:
A. They rapidly lose their effectiveness when exposed to sunlight.
B. They rapidly degrade in the presence of oxygen.
