When wall voids and dead spaces must be treated from small openings, the most effective formulation to use would be:  \nA. Liquid residual spray.  \nB. Granules.  \nC. Wettable powder.  \nD. Dust.  \n2. The amount of drift increases as:  \nA. Nozzle size increases.  \nB. Droplet or particle size increases.  \nC. Wind speed increases.  \nD. Sprayer pressure decreases.  \n3. You are calibrating a sprayer. You find that your sprayer is putting out 2 gallons per minute of spray, and that it takes 20 minutes for you to spray an acre of land. How much spray per acre is your sprayer putting out?  \nA. 0.1 gallons per acre.  \nB. 10 gallons per acre.  \nC. 40 gallons per acre.  \nD. 160 gallons per acre.  \n4. You know that a tank full of pesticide will cover 5 acres of land. You wish to apply a pesticide at a rate of 4 pints per acre. How many pints of pesticide should be placed in the tank?  \nA. 0.80 pints.  \nB. 1.25 pints.  \nC. 10 pints.  \nD. 20 pints.  \n5. To clean a clogged nozzle, use:  \nA. Water or detergent and a soft brush.  \nB. A steel bristle brush.  \nC. A needle or pin.  \nD. Your mouth to blow it clear.  \n6. Dusters should be cleaned periodically and emptied of their contents when stored because most insecticidal dusts:  \nA. Attract moisture, causing caking problems.  \nB. Breakdown quickly in storage.  \nC. Are highly corrosive, damaging the equipment.  \nD. Rapidly dry out, losing their effectiveness.  \n7. You wish to spray weeds at a dosage rate of 5 pounds of weed killer in 100 gallons of water per acre. How much weed killer will you need to spray 10 acres?  \nA. 2 pounds.  \nB. 5 pounds.  \nC. 50 pounds.  \nD. 500 pounds.  \n8. You can increase the application rate by decreasing the:  \nA. Pressure.  \nB. Tank capacity.  \nC. Ground speed.  \nD. Size of the nozzle orifice.  \n9. The adjustment of application equipment to apply a pesticide formulation at a desired application rate is called:  \nA. Dilution.  \nB. Formulation.  \nC. Preventive maintenance.  \nD. Calibration.  \n10. The best method of making major changes in the output rate of sprayers is to change the:  \nA. Pressure.  \nB. Ground speed.  \nC. Nozzle size.  \nD. Viscosity of the spray formulation.  \n11. If your sprayer’s output rate is 4 gallons per minute and you treat 2000 square feet per minute, then your application rate is:  \nA. 1 gallon per 8000 square feet.  \nB. 2 gallons per 1000 square feet.  \nC. 4 gallons per 1000 square feet.  \nD. 8 gallons per 1000 square feet.  \nThese questions are meant primarily to give an idea of the exam questions, and may not accurately reflect current reference materials or emphasis of exams  \n12. The directions on an emulsifiable concentrate insecticide label say “Apply spray containing 10 tablespoons per gallons of water at a rate of 1 gallon to 1000 square feet.” How much spray should you mix to apply to an area that is 50 feet long and 30 feet wide?  \nA. ½ gallon.  \nB. 1 gallon.  \nC. 1.5 gallons.  \nD. 3 gallons.  \n13. In the example above, how much concentrate should you use if you have to make 2 gallons of finished spray? Hint: 2 tablespoons (Tbs) = 1 fluid ounce (fl oz) .  \nA. 10 fl oz.  \nB. 10 Tbs.  \nC. 5 fl oz.  \nD. 15 Tbs.  \n14. A vehicle traveling at a rate of 12 miles per hour will travel how many feet in 30 seconds?  \nA. 123 feet.  \nB. 528 feet.  \nC. 729 feet.  \nD. 450 feet.  \n15. Biological control means:  \nA.
