An applicator is calibrating a four-nozzle boom sprayer. After collecting the output from each nozzle for one minute, the following volumes are recorded:

• Nozzle 1: 20 oz
• Nozzle 2: 21 oz
• Nozzle 3: 20 oz
• Nozzle 4: 25 oz

Using a maximum allowable variation of 10% from the average nozzle output, what should the applicator do?

A rectangular lawn measures 50 feet by 40 feet. A 500-square-foot paved area inside it will not be treated.

The label requires 2 fl oz of concentrate per gallon of finished spray. One gallon treats 1,000 square feet.

How much finished spray and concentrate are required?

A technician mixes a wettable powder pesticide according to the label. After the sprayer sits unused for 30 minutes, a layer of material appears at the bottom of the tank.

What is the BEST action before continuing the application?

A customer reports German cockroaches in the kitchen. The technician finds garbage, grease, food debris, a dirty stove, and a leaking pipe.

Which action is the BEST IPM approach?

A technician treats a broadleaf weed growing from the same area every year. The leaves die after treatment, but new shoots appear several weeks later from underground roots.

What is the BEST explanation and management approach?

A technician inspects a pesticide compartment. All containers are sealed, upright, and labeled. Liquid concentrates sit in a leak-resistant tray on the upper shelf. Boxes containing granular bait and wettable powder are secured below them.

Which change is MOST appropriate?

An EPA-registered pesticide label allows treatment at buildings. State law requires warning signs 24 hours after application. A city ordinance, authorized by state law, prohibits pesticide applications within 50 feet of an open playground.
