WPS applies to what type of pesticides

Answer 4

agricultural

Question 5

what is an REI

Answer 5

the period of time workers are not allowed into the treated field (most have a 4-48 REI)

Question 6

what contributes to the breakdown of of pesticides

Answer 6

light, heat, oxygen, microbes, bacteria and fungi

Question 7

What is the best way to avoid groundwater contamination

Answer 7

Dont use pesticides! second best is IPM

Question 8

ODAFF

Answer 8

OK department of Agriculture, Food and Forestry. distributes licenses for all commericial applicators regardless of whether or not they apply RUP’s

Question 9

When can a mist blower for hormone type herbicides be used?

Answer 9

forest nursery and timber productions areas where the control of undesirable vegetation with hormone type herbicide is necessary
Range, pasture, and crop areas where control of udnesirable vegetation with a hormone type herbicide is necessary.
( when terrain cannot be easily be covered by other types of equipment)

Question 10

Commercial applicators are required to keep the following records for OK:

Answer 10

Start and Stop time of application (date of application)
Total amount of pesticide used
Name and address of the commercial or non commercial company
Name and address of the person whom applied
Legal description of the land where applied. St. address not p.o box
Dilution rate for mixing
Total amount of mix used
Trade Name of mix, EPA registration number or product used
Target pest for application, site of application
REI according to label
A copy or label or labeling
Copies of contracts issued, copies of wood infestation reports issued *KEEP FOR TWO YEARS

Question 11

USDA record keeping for RUP’sl:

Answer 11

Brand or product name and EPA registration#
Total amount applied
Size of area treated
Crop commodity, stored product or site
Location of application
Month, day and year applied
Applicators name and cert. #

Question 12

IPM for Ag. crops includes

Answer 12

resistant varieties of crop rotation
cultural practices
beneficial organisms
all of which need to be considered before the use of pesticides

Question 13

Annual weeds

Answer 13

complete their lifecylce in less than one year. Some plants are winter or summer annuals. Summer annuals start in the spring and die before fall. Some plants are both. Knowing their lifestages helps to control these plants

Question 14

Biennial weeds

Answer 14

Complete their lifecycles within two years. In the first the plant forms basal leaves and tap root. in the second year it flowers, matures and dies. These are most susceptable to herbicide treatmeants when they are still in rosette stage before putting up a flower stalk.

Question 15

Perennial weeds

Answer 15

Live more than two years and live almost indefinitely. some by seed, a lot by rhizomes, bulbs, tubers or budding roots. Easiest to control as seedlings. Translocated herbicides are the most effective at control, best application time is right after plant has leafed out fully in springcult

Question 16

Propagules: perennial weeds

Answer 16

Contain buds for the production of new shoots and they also store the food to supply energy to the shoots. until leaves develop and begin photosynthesis

Question 17

cultural control

Answer 17

smother crops or crop rotation

Question 18

mechanical control

Answer 18

hand pulling, hoeing, mowing, flooding, burning, tilling and smothering with nonliving materials such as plastic.

Question 19

Biological control

Answer 19

consists of one living organism controlling another, without harming the crop plant. exp. insects, and geese in vinyards

Question 20

Chemical control

Answer 20

herbicides…duh.

Question 21

Contact Herbicide

Answer 21

an herbicide that kills primarily by contact with plant tissue

Question 22

translocated herbicide

Answer 22

herbicides that are “translocated” to sites within the plant to disrupt an important process in photosynthesis or growth.

Question 23

Germination inhibitors

Answer 23

applied to the soil and affect seeds by preventing germination. almost no foliar activity, and are no translocated. Control grasses, better than weeds and no effect on perennials

Question 24

Photosynthesis inhibitors

Answer 24

generally soil applied but can also be post emergence on small seedlings. they are trans-located from the soil through the xylem. Control annual broad leafs better than grasses.

Question 25

Meristem inhibitors

Answer 25

Affect the cell division of the plants meristem. (growing points of plants) by inhibiting production of amino acids. Plant resistance can easily develop.

Question 26

Contact Action

Answer 26

applied post emergence to seedling annual weeds to burn them off. Control annual broadleaf weeds better than grasses because the growing point is shielded in young grasses with leaf foliage.

Question 27

Auxin Growth Inhibitors

Answer 27

Control broadleaf weeds and can be selectively used in most grass type crops. they translocate to the growth areas of the plant where they block a vital process. small doses from drift from this group can cause injury to non target plants.

Question 28

Post emergence translocated herbicides

Answer 28

primarily post emergence for grass control. translocate readily and should be applied to actively growing plants. metabolic inhibitors, pigment inhibitors and meristematic inhibitors. Can be selective or non selective

Question 29

Pre plant herbicides

Answer 29

herbicides applied to soil before the crop is planted
