Free WV-PEST Practice Questions

Question 1

Three days after a crop was treated, a supervisor wants workers to inspect leaves for pest damage and harvest produce. The label specifies a 12-hour restricted-entry interval and a 7-day preharvest interval. Required warning signs have been removed, no later pesticide application has occurred, and all other worker-entry conditions are met. Which work can be assigned today?

Accepted Answer

Permit inspection, but delay harvesting until the preharvest interval ends.

Answer

Delay both tasks until the 7-day preharvest interval has also ended.

Answer

Permit both tasks because the restricted-entry interval has already ended.

Answer

Permit both tasks if workers wear the label's early-entry protective equipment.

Question 2

Treatment records show that a crew has alternated two insecticide brands for several seasons. The active ingredients differ, but both labels identify the same mode-of-action group. Resistance to that group has now been confirmed in the target pest. When another insecticide treatment is justified, which choice most directly addresses the resistance problem?

Accepted Answer

Use an effective, labeled insecticide from a different mode-of-action group.

Answer

Replace one brand with a different formulation of the same active ingredient.

Answer

Shorten the interval between the two brands as far as their labels permit.

Answer

Keep alternating the brands, but use the highest permitted rate of each.

Question 3

A treatment map shows 20,000 square feet inside a property boundary, including 5,000 square feet of pavement and planting beds that will not be sprayed. The turf herbicide label calls for 1.6 fluid ounces of product per 1,000 square feet. At the working pace, the calibrated sprayer delivers 2 gallons of finished spray per 1,000 square feet. Which batch matches this job?

Accepted Answer

24 fluid ounces of product in 30 gallons of finished spray.

Answer

32 fluid ounces of product in 40 gallons of finished spray.

Answer

48 fluid ounces of product in 30 gallons of finished spray.

Answer

24 fluid ounces of product in 40 gallons of finished spray.

Question 4

Late in a hot shift, an insecticide mixer becomes weak and nauseated after concentrate leaks onto his shirt. He is drooling, has very small pupils, and develops noisy, difficult breathing. Clean water and appropriate protective equipment are immediately available. A coworker suggests treating this as heat exhaustion. What response takes priority?

Accepted Answer

Call 911 while protected coworkers remove the contaminated shirt and immediately rinse exposed skin with clean water.

Answer

Take him to a clinic before removing his shirt to avoid delaying medical treatment.

Answer

Move him into shade, offer cool fluids, and reassess him after a rest period.

Answer

Let him recover in fresh air before deciding whether poison advice is needed.

Question 5

After a heavy storm, pesticide residue is found in a stream below a steep, recently treated field. The pesticide is only slightly soluble in water and binds strongly to soil particles. The runoff is muddy. Which transport pathway is most consistent with these findings?

Accepted Answer

Runoff transport of residue attached to eroded soil.

Answer

Vapor movement following volatilization of residue from treated surfaces.

Answer

Spray drift depositing airborne droplets directly onto the water.

Answer

Leaching of dissolved residue through soil into the groundwater.

Question 6

In a clean-water catch test, five matched boom nozzles each discharge about 0.40 gallon per minute; a sixth discharges 0.50 gallon per minute. All six have the same model marking, pressure is confirmed equal at the nozzles, and the tips and strainers have been cleaned. What most likely explains the sixth nozzle's output?

Accepted Answer

Wear enlarging the orifice and increasing discharge.

Answer

A partial blockage in that nozzle's strainer.

Answer

Excessive overlap between adjacent spray patterns.

Answer

A regulator fault increasing pressure across the whole boom.

Question 7

An applicator identifies a troublesome weed in established turf. A herbicide is labeled for that turf site, but the weed is not named on the label. The product is known to control the weed, the label has no restriction limiting use to listed pests, and no stricter state requirement applies. All other use directions can be met. Under FIFRA, which action is permissible?

Accepted Answer

Treat the weed at the labeled site while observing all applicable use restrictions.

Answer

Choose any effective rate because the label does not name this particular weed.

Answer

Postpone treatment until EPA adds the weed to the product's approved labeling.

Answer

Treat the weed at other sites once its susceptibility to the active ingredient is established.

Question 8

At annual fit testing, a pesticide handler obtains an overall quantitative fit factor of 140 with the half-facepiece respirator selected for the job. Medical clearance and respirator training are current; the cartridges meet label requirements, and the respirator is appropriate for the use conditions. How should the fit-test result be used?

Accepted Answer

Accept this half-facepiece fit test, but require a user seal check each time the respirator is donned.

Answer

Accept the fit test as a substitute for user seal checks over the next year.

Answer

Require a separate qualitative fit test before accepting this quantitative fit-test result.

Answer

Withhold respirator work until this half-facepiece achieves a fit factor of at least 500.

Question 9

A client requests a fungicide for a black film on shrub leaves. The film wipes off, the foliage is sticky, and colonies of small sap-feeding insects are present on shoots above the affected leaves. The leaf tissue beneath the film is intact. Which approach targets the source of the problem?

Accepted Answer

Manage the sap-feeding insects that are supplying honeydew.

Answer

Apply a fungicide to cure a primary infection within the leaf tissue.

Answer

Wash the coating off the foliage while leaving the insect colonies untreated.

Answer

Reduce leaf wetness to interrupt a moisture-driven infection of the shrubs.

Question 10

A pesticide's front panel bears DANGER but not POISON or a skull-and-crossbones. Its precautionary statement warns of irreversible eye damage. A technician argues that the missing poison symbol means DANGER is the wrong signal word. Which interpretation resolves the disagreement?

Accepted Answer

A severe eye hazard can require DANGER without the POISON designation.

Answer

DANGER makes the product restricted use even when the poison symbol is absent.

Answer

DANGER is reserved for chronic effects when POISON is absent.

Answer

Eye injury determines eyewear requirements but cannot determine a product's signal word.
