Check whether each statement is true or false.

1. The Michigan Department of Agriculture and Road Development does not have the authority to suspend the registration of a pesticide.

2. Licensed pesticide dealers may sell restricted use pesticide only to certified applicators.

3. Michigan law does not require the use of antisiphon devices on equipment that draws water.

4. Immediate access to a spill kit is not required when mixing amd loading pesticides.

5. Pesticide mixing and loading and washing and rinsing of equipment (other than hand held) must be done on a impervious pad.

6. If off target drift is anticipated because of the nature of the application, a drift management plan must be in place.

7. If you store and distribute bulk pesticides in certain quantities, you must comply with Michigan Regulation 640 rules for commercial pesticide storage.

8. After collecting the rinsate from triple rinsing pesticide containers, you may pour the rinsate down the drain.

9. In Michigan, empty pesticide containers that have been triple rinsed or power rinsed and punctured may be brought to a MDARD recycling facility or disposed of in a regular licensed Type II sanitary landfill.

10. It is not necessary to contact the MDEQ when a pesticide spill drains into a ditch.

11. Your first response after a pesticide spill is to immediately clean it up.

12. The MIOSHA Right-to-Know-Act requires employers to obtain and retain material safety data sheets (MSDS) on all hazardous chemicals (including pesticides) for employee review.

Check the correct answer.

1. Which statement is true about sprayer tanks?

2. The amount of flow needed for agitation depends on:

3. Which is the best type of pump to use with wettable powders and abrasive materials in low pressure sprayers?

4. Which is the best type of pump to use for applying foliar herbicides, insecticides, and fungicides under higher pressures.

5. What two parts of a flow control assembly used with roller pumps, diaphragm pumps, or piston pumps allow the spraying pressure to be adjusted properly?

6. Which sprayer part must be included in every sprayer system and be used for calibration and operation in the field?

7. Nozzle flow rate is a function of:

8. What does volume median diameter (VMD) refer to?

9. Droplet sizes less than 200 microns are considered:

10. What's the purpose of a nozzle check valve?

11. When should you clean or replace a nozzle?

12. What two characteristics determine the spray pattern of a nozzle?

13. Where would you use a 100-mesh strainer?

14. What can be done to minimize pressure drop in sprayers.

15. The nozzle flow rate varies with:

16. How does ground speed of the sprayer affect the gallons of spray applied per acre (gpa)?

17. You found that it took 30 seconds to travel 300 feet with your sprayer. What is your travel speed in miles per hour (mph)? (1 mph = 88 feet in 60 seconds)

18. You plan to use flat fan nozzles to apply 25 gallons per acre. The nozzles are spaced 20 inches apart and your travel speed is 5 mph. What is the desired output of the nozzles in gallons per minute (gpm)? (gpm = gpa x mph x w/5940). w= width of nozzle spacing.

19. You measure the output of five nozzles and receive the following results:

Which nozzle(s) should be cleaned or replaced?

20. The manufacturer's catalog lists a nozzles's output as 0.4 gpm. Using the time flow method of calibration, what range of values in ounces per minute do you need to collect to be within 5 to 7 percent of the catalog value? (Note: 1 gal = 128 ounces)

21. You will be doing a broadcast spray application with nozzles spaced 30 inches apart. What is the appropriate travel distance to stake out when using the ounces=gallons method of calibration?

Travel distance (feet) = 4080/nozzle spacing (inches)

22. When you are traveling the distance you determined in the ounces=gallons method of calibration, what value should you be measuring.

23. When calibrating a broadcast sprayer using the ounces=gallons method, you find that the average nozzle output for the travel time is 25 ounces. What is the spray rate in gallons per acre?

Gallons per acre = average output ounces of nozzles.

24. After calibrating your sprayer using the ounces=gallons method of calibration, you find that the output is 20 gallons per acre. The label recommends a spray rate of 25 to 35 gallons per acre. What would be the best way to adjust the output of your sprayer?

25. What is an improper sprayer maintenance practice?

26. Which is an improper sprayer cleaning practice?

27. Which is an improper practice for winterizing a sprayer.
