Checking and Replacing Worn Nozzles

N69199-UN-02MAR05

• A—NEW SPRAY TIPS produce a uniform distribution when properly overlapped.
• B—WORN SPRAY TIPS have a higher output with more spray concentrated under each tip.
• C—DAMAGED SPRAY TIPS have a very erratic output—overlapping and under applying.

A major cause of improper spray application is nozzle wear. Maintenance and timely inspection helps to identify worn nozzles and extend service life.

Over-application can cause:

• Crop damage
• Chemical carry-over, affecting future crops
• Ground water contamination

Under-application may:

• Require additional field passes
• Cause inadequate weed, pest or disease control, all of which impact crop yields
