Free RI-PEST Practice Questions

Question 1

An applicator identifies a damaging insect on ornamental shrubs. A registered insecticide is effective against the insect and is labeled for those shrubs, but the insect is not named on the label. The labeling does not restrict use to listed pests, and the proposed application meets all other label and state requirements. Under FIFRA Section 2(ee), how should the missing pest name affect the decision?

Accepted Answer

The insect may be treated on the labeled shrubs without a pest-list amendment.

Answer

Treatment must wait until the manufacturer adds the insect to the product label.

Answer

Treatment is allowed only if the rate is reduced below the labeled rate.

Answer

An emergency-use authorization is required before this insect can be treated on the shrubs.

Question 2

A boom sprayer delivers 30 gallons per acre. The work order covers a 5-acre property, but a 1-acre pond and a 1-acre paved yard are excluded from treatment. The label rate is 1 quart of product per treated acre. What tank load will provide exactly enough spray mixture for the job?

Accepted Answer

6 pints of product, with water added to make 90 gallons of finished spray.

Answer

10 pints of product, with water added to make 150 gallons of finished spray.

Answer

6 pints of product, with water added to make 150 gallons of finished spray.

Answer

3 pints of product, with water added to make 90 gallons of finished spray.

Question 3

A customer requests fungicide for shrubs covered with a black film. The film rubs off, the leaves beneath it are sticky, and live sap-feeding insects are clustered on the shoots. No dead leaf spots or rotted tissue are found. Which explanation best identifies the problem to address?

Accepted Answer

Sooty mold is growing on honeydew supplied by the sap-feeding insects.

Answer

A primary fungal leaf infection is producing both the black film and sticky residue.

Answer

Leaf-mining larvae are leaving dark frass that accounts for the surface coating.

Answer

Pesticide injury has blackened the leaf tissue and caused the sticky deposits.

Question 4

Pesticide concentrate splashes into an applicator's eye, causing pain and blurred vision. The applicator is wearing contact lenses. Clean running water is within reach, and a coworker is already calling Poison Control. What should the applicator do immediately?

Accepted Answer

Hold the eye open and begin rinsing gently with clean water.

Answer

Remove the contact lens before allowing any rinse water into the eye.

Answer

Keep the eye closed while the coworker arranges transportation for medical treatment.

Answer

Wait for Poison Control to identify the formulation before beginning an eye rinse.

Question 5

Six hours after a commercial lawn treatment at a Rhode Island home, the spray has completely dried. The product label excludes people and pets until the spray is dry; no other entry restriction applies. The lawn signs say 'Keep Posted for 48 Hours.' The homeowner asks what the signs mean for using the lawn. Which explanation is accurate?

Accepted Answer

People and pets may enter now, but the signs stay until 48 hours after application.

Answer

People and pets must remain off the lawn for the entire 48-hour posting period.

Answer

The signs may be removed now because the label's dry-spray entry condition has been met.

Answer

Adults may enter now, but children and pets must wait until the 48-hour posting period ends.

Question 6

A review of an IPM program finds that the last three insecticide applications used different trade names but the same mode of action. Pest identification, timing, and application quality were satisfactory. The applicator wants the next justified treatment to interrupt repeated selection by that mode of action. Which change accomplishes that?

Accepted Answer

Use a labeled, effective product with a different mode of action.

Answer

Alternate trade names containing active ingredients from the same mode-of-action group.

Answer

Switch between liquid and granular formulations of the same active ingredient.

Answer

Increase application frequency while retaining the same labeled product and rate.

Question 7

A treatment site has sandy soil, little organic matter, and a shallow water table. Four products would be applied at the same rate under the same weather conditions. Which combination of pesticide properties creates the greatest potential for leaching to groundwater?

Accepted Answer

High water solubility, weak soil adsorption, and long persistence.

Answer

High water solubility, strong soil adsorption, and short persistence.

Answer

Low water solubility, weak soil adsorption, and short persistence.

Answer

Low water solubility, strong soil adsorption, and long persistence.

Question 8

A vegetable grower wants a crew to scout treated plants and harvest produce. The pesticide application ended 36 hours ago. Its label specifies a 12-hour restricted-entry interval and a 7-day preharvest interval, with no additional entry restrictions. Which of the planned activities is permitted at this point?

Accepted Answer

Scouting is permitted, but harvesting must wait.

Answer

Harvesting is permitted, but scouting must wait.

Answer

Both activities are permitted because the restricted-entry interval has elapsed.

Answer

Neither activity is permitted until the seven-day preharvest interval has elapsed.

Question 9

A qualified noncertified employee is applying a restricted-use pesticide at a Rhode Island job site. The correctly certified commercial supervisor plans to leave for another job and remain reachable by phone. The employee has the label, required PPE, and use-specific instructions; the label does not expressly require the supervisor's physical presence. What still prevents the proposed arrangement?

Accepted Answer

Rhode Island requires on-site supervision for this noncertified applicator's pesticide use.

Answer

The supervisor must remain within a thirty-minute drive of the application site.

Answer

The employee must hold a commercial certificate even when working under direct supervision.

Answer

The supervisor must obtain the customer's written permission before supervising by telephone.

Question 10

Two pesticide formulations both carry the signal word WARNING. Comparable acute oral studies report an LD50 of 180 mg/kg for Product A and 1,800 mg/kg for Product B. The studies used the same test species and method. Which conclusion is supported by these results?

Accepted Answer

Product A has greater acute oral toxicity than Product B.

Answer

Product B is more acutely toxic through skin contact.

Answer

Identical signal words establish equal acute oral toxicity.

Answer

Product B has less chronic toxicity because its oral LD50 is higher.
