6.14 Nozzle Selection
Correct selection of nozzle and calibration of the sprayer are critical to
achieve accurate and cost effective use of farm crop protection products.
Your HARDI sprayer has been supplied with 110
°
flat spray Green Color
Tips™ that will apply approximately 20 U.S. GPA at 30 PSI and 5 MPH.
The 110
°
flat spray nozzle was chosen rather than the 80 degree nozzle
for two reasons: 1- It may be used at a lower minimum height which
reduces the risk of wind drift; 2- It's greater overlap permits better unifor-
mity of spray distribution, particularly if boom height varies on rough
ground. Normal boom height setting with 110
°
nozzles is 18" to 20" above
the crop or weeds, whichever is taller.
Should you wish a different application rate or different type of nozzle,
HARDI manufactures a nozzle for virtually every need.Refer to the Hardi
Nozzle Catalog for the complete range of Hardi Nozzles.
ALWAYS CONSULT YOUR CHEMICAL SUPPLIER FOR RECOM-
MENDED CHEMICAL RATE AND WATER APPLICATION RATE.
ALWAYS WEAR PROTECTIVE GLOVES WHEN HANDLING
NOZZLES.
The following tables show what types of spray nozzles are suitable for
different applications. Refer to the HARDI nozzle catalogue to find the
