Protect every application with an adjuvant built for better coverage and deposition.
- In-season applications are a significant investment; protect your ROI on every pass by including a high-performance adjuvant in your tank mix.
- Adjuvants enhance spray performance by improving coverage, reducing drift, and increasing adhesion to target surfaces.
- Water softener Adjuvants reduce mineral tie‑up, keeping more active ingredient available where it matters.
Every in-season decision matters, especially when input costs are high, margins are tight, and field conditions are unpredictable. During fungicide season, the most expensive pass isn’t the one you make, it’s the one you have to make again.
Make every pass count. Adding the right adjuvant helps protect your investment, improve coverage, and ensure your fungicide performs as intended. Adding an adjuvant to your tank helps protect your investment, improve performance, and ensure your fungicide works as intended, every acre, every time.
Protect your investment on your next pass.
Avoid in-season expenses that don’t deliver a clear return. For a small investment, adding the right adjuvant to the tank can help improve performance and deliver measurable returns. “By increasing your yield by one bushel, you’ll more than pay for the adjuvant application,” says Dr. Connor Ferguson, Wilbur-Ellis Adjuvant Portfolio Manager.
Adjuvants help optimize the performance of fungicides in real-world conditions. They can improve coverage and plant uptake, condition the water to prevent mineral interference, and help keep spray droplets on target.
Dr. Ferguson explains, “It’s about recognizing the investment growers have already made in crop protection and overall fertility, and making sure they get the most out of that crop.”
The benefits of adjuvants
In hot, wet, and unpredictable conditions, fungicide applications need to reach the intended target, spread evenly, and penetrate the plant surface to perform effectively. R-11® Spreader-Activator is a proven, nonionic surfactant for helping growers get more from every fungicide pass.
R-11 reduces surface tension, allowing spray droplets to spread more completely across the plant surface. “Including something like R-11 in the spray tank will ensure that more of the growers’ investment is staying where it’s applied,” notes Ferguson.
With a 90% active-ingredient load, excellent tank-mix compatibility, and 50 years of proven performance, R-11 has earned its place as a standard nonionic surfactant in agricultural applications and university research.
R-11 is the go-to choice for growers looking for a dependable adjuvant that delivers consistent spreading, activation, and compatibility.
Beyond drift and coverage, adjuvants also enhance how fungicides interact with the plant.
Many common fungicide chemistries, such as strobilurins and triazoles (including propiconazole and tebuconazole), are lipophilic and naturally associate with plant oils and waxes. ALLEVIATE®, an MSO-based adjuvant with NPE-free nonionic surfactant, is designed to complement these chemistries by improving penetration, spreading, and spray coverage, helping enhance uptake and overall fungicide performance. ALLEVIATE also provides excellent drift-reduction properties, giving you a multifunctional product for your fungicide applications.
Don’t overlook water quality.
Water is at the center of every application. Yet it can limit the effectiveness of your next pass.
Many growers’ water sources can contain high levels of minerals that can interfere with fungicide performance. Without proper conditioning, those minerals can bind to active ingredients, reducing efficacy.
Adding a water conditioner, like RETRIBUTION® or BRONC® MAX, helps prevent the tie-up of the fungicide, ensuring your application performs as intended. “Adding a water conditioner to every tank, every time, is going to ensure that your water does not tie up that pesticide,” explains Ferguson.
