The Ulitimate Question: Which Wilger Spray Tip Series Is Best? (ER, SR, MR, DR, or UR)

With multiple Wilger spray tip series available — ER, SR, MR, DR, and UR — often in the same flow rate, choosing the right one can feel confusing. This commonly leads to the question:

“Which Wilger spray tip series is the best?”

The short answer is simple: There is no single “best” spray tip series. The best spray tip depends on how, where, and what you are spraying.

Why There Is No “Best” Spray Tip Series

Spray application requirements vary dramatically between crops, chemicals, application timing, sprayer type, speed and rate requirements, and drift  sensitivity.

A spray tip that performs perfectly for a burn-off herbicide may be completely wrong for a fungicide application.

What Defines the Best Spray Tip?

The best spray tip is one that:
• Is correctly sized for your target speed and application rate
• Produces the ideal droplet size for the chemical and crop
• Maximizes spray efficacy
• Minimizes off-target drift

Why Wilger Manufactures Multiple Spray Tip Series

Wilger manufactures five different spray tip series across the same flow rates to give applicators a sliding scale of droplet size options.

Each series is engineered to deliver a different droplet spectrum at the same flow rate, allowing applicators to fine-tune spray performance without sacrificing speed or drift control.

Wilger Spray Tip Series Overview

ER – Finer droplets for maximum coverage
SR – Medium droplets for general-purpose spraying
MR – Medium-to-coarse droplets for flexibility
DR – Coarse droplets for drift reduction
UR – Ultra-coarse droplets for maximum drift control

Using Tools to Simplify Spray Tip Selection

Wilger provides detailed nozzle performance data and digital tools like Tip Wizard. When combined with chemical labels and agronomist recommendations, spray tip selection becomes far simpler.

 Spray Tip Selection with PWM Sprayers

Pulse Width Modulation (PWM) sprayers increase spray tip flexibility by controlling flow electronically rather than by pressure. This allows applicators to maintain consistent droplet size across a wide range of speeds.

PWM Spray Tip Selection Example

Example application: Systemic herbicide burn-off.
Target spray quality: Coarse spray (approximately VMD 400 microns).
Example chemical: Glyphosate.

Using PWM technology and Wilger Tip Wizard, applicators can compare spray tip series at the same flow rate while maintaining the desired droplet size.

Final Takeaway

There is no universal best Wilger spray tip series. The best spray tip is the one that matches your application rate, speed, chemical, crop, drift requirements, and sprayer technology.
