Keeping Applications on Target: How Precision Tech Protects Coverage and ROI in Mid‑Season

Mid-season spraying is an entirely different challenge than early vegetative passes. By the time crops hit rapid growth stages, sprayer operators face tighter spray windows, shifting wind patterns, taller canopies, and a much higher risk of drift or under-coverage. It's also when some of the most expensive crop protection products of the year are applied, meaning the cost of misapplication climbs fast.

To protect coverage and ROI during these higher-risk passes, many operators are upgrading the tech on their current sprayers. Raven Hawkeye® 2 and VSN® Visual Guidance work together to help the sprayer stay aligned, maintain droplet consistency, and deliver crop protection products deep into dense canopies, even as field conditions get tougher.

Here's 5 ways these technologies keep your mid-season applications on target.

1. Managing Wind, Heat, and Drift When Conditions Get Tougher

As temperatures rise in mid-season, evaporation and drift risk increase. Spray windows shrink, and operators often need to move quickly between "safe to spray" and "shut it down" conditions.

Hawkeye® 2 helps mitigate drift risk by keeping pressure and droplet size consistent, even during speed changes, awkward turns, or rolling terrain. When the droplet stays in the optimal size range, it's less vulnerable to mid-season environmental swings.

Meanwhile, VSN® keeps the sprayer perfectly centered, reducing the risk of misalignment that can push booms closer to crop edges or cause uneven coverage.

2. Ensuring Uniform Droplet Size for Dense Canopies

As crop biomass increases, getting product where it needs to go gets harder. Dense canopies can block spray patterns, leading to:

• Under-coverage
• Missed disease-pressure zones
• Weak penetration to the lower canopy

Hawkeye® 2 counters this by delivering nozzle-by-nozzle control, keeping each droplet consistent as operators speed up, slow down, or move across uneven terrain. Nozzle-level pulse-width modulation maintains:

• Proper droplet size
• Uniform pressure
• Accurate application rates

That combination helps the spray penetrate tall, dense mid-season crops more effectively, improving coverage consistency and crop protection efficacy.

3. VSN® Keeps the Sprayer Centered in Tall Crops

Mid-season is when physical crop contact risk peaks. Tall corn and fast-growing soybeans create tight lanes with:

• Narrower visual reference points
• Taller biomass closing in on tires
• Higher stress for operators making late-day passes

Here's where VSN's multi-sensor guidance system excels. Its camera-based visual guidance ("stereo vision") handles the early season, while radar sensors guide the sprayer through full canopy at speeds over 20 mph, helping maintain sub-inch accuracy without ever touching the crop.

Perfect alignment helps:

• Reduce mechanical crop damage
• Maintain even boom height
• Improve rate accuracy
• Reduce skips and overlap in tall crops

This means cleaner passes, and healthier plants, during the season's most vulnerable growth periods.

4. Maintain Rate and Pressure Consistency Across Every Acre

In mid-season, operators often push harder to beat incoming weather or cover acres quickly with fungicide application timing. Speed changes are common, but inconsistent rate control during those changes can lead to yield-robbing errors.

Hawkeye® 2 eliminates this risk by maintaining ideal pressure and rate across the entire boom, even when:

• Turning on headlands
• Climbing slopes
• Navigating uneven fields
• Speeding up to cover acres quickly

Consistency equals confidence, especially when spraying high-value products in high-value growth stages.

5. Combat Operator Fatigue During Long, High-Stakes Spray Days

Mid-season passes often mean:

• Long hours
• Changing light conditions
• Difficult visibility
• High crop pressure
• Tight spray windows

It's the perfect recipe for operator fatigue, and fatigue is the perfect recipe for mistakes.

VSN® dramatically reduces operator workload by automatically taking over steering, which research has shown reduces operator stress events by nearly 50% compared to manual steering. Meanwhile, Hawkeye® 2 automates the fine spray adjustments operators would normally worry about, letting them stay focused on safety and consistency.

Less fatigue means fewer errors and better applications.

Mid-season is when coverage matters the most - and when mistakes cost the most. Pairing VSN® Visual Guidance with Hawkeye® 2 Nozzle Control gives operators the precision, confidence, and consistency they need to:

• Keep spray on target
• Improve coverage in tall canopies
• Manage drift risk
• Protect ROI on high-value applications
• Reduce fatigue during the hardest runs of the season

You don't need a new sprayer to get mid-season precision. You just need the right upgrades.
