INTRODUCTION
It is important to apply chemicals as recommended by the manufacturer’s of the product. In order to do so,
the spraying system must be properly calibrated.
Determine the speed at which the sprayer will be driven while applying the chemicals. To select the best
speed, consider the lay of the land, the condition of the soil, the type of crops, the height of the crops, etc.
Select the nozzles spacing (distance between each nozzle on the spray boom) best suited for the intended
spraying job. For help in determining the nozzle spacing and height of the boom, refer to the Spray Product
Catalog that accompanies this manual.
There are several types and sizes of nozzles. Select (as recommended by the catalog) and install the type
and size of nozzles best suited for the intended spraying job. The type of nozzle will be based on the product
being sprayed and the type of crop it is being use on. The size of nozzles selected will be based upon the
speed the sprayer will travel, the nozzle spacing, and the number of gallons one intends to apply per acre.
TIP SELECTION:
There are several things to consider when selecting the type of nozzle you need for the intended spray
job. Whatever your personal preference is, be sure that the nozzle complies with the chemical manufacturer’s
standards for spray control and also any environmental standards that might be in place for your region.
(Some regions may have restrictions on “drift” control)
Once you have chosen a type of nozzle, you must choose the size of the nozzle. There are
3
main things
to consider when choosing the size:
1)
recommendation of gallons per acre by the chemical manufacturer,
2)
the speed in which you intend to travel across the field while spraying,
3)
and the nozzle spacing (distance
between tips).
See the next page for information on how to use this information to select a tip size.
IMPORTANT:
The key to an effective spray job starts with
the selection of the spray tip!
Refer to the Spray Product Catalog that accompanies this
manual for more information.
