Appendix A – Broadcast Spray Calibration Tables

Below are some guidelines to help you calibrate your broadcast sprayer. This is a very important step in operating the broadcast sprayer such that too much or too little chemical may be applied.

1.Using Table 1, find a table that corresponds with the chemical manufacturer’s suggested application rate(gallons per acre, gallons per 1000 sq. ft., or gallons per 100 sq. ft.).

2.Find the application rate that is closest to the chemical manufacturer’s recommendations.

3.The speed to drive your ATV is listed below the application rates.

TABLE 1


	Spray	Pressure	GALLONS PER ACRE – based on water at 40” spacing

4.Use Table 2 to choose the throttle setting on your ATV.

TABLE 2


	Speed	Time required in seconds to travel a distance of:
	(MPH)
	(MPH)	100 ft.	200 ft.	300 ft.
	1	68	136	205
	2	34	68	102
	3	23	45	68
	4	17	34	51
	5	14	28	41
	6	11	23	34
	7	9.5	19	29

5.The coverage area can be found by dividing tank size by the application rate. Example: 26 gallons divided by 12 gallons/acre = 2.16 acre of coverage per tank.
