Adjuvants: The Key to Making Every Spray Count

Spraying your crops isn’t just about applying chemicals; it’s about making sure those chemicals work exactly how they’re supposed to. That’s where adjuvants come in. These powerful additives make your herbicides, fungicides, and pesticides more effective.

At Ag Plus Cooperative, we offer a lineup of adjuvants designed to solve the most common spraying problems—drift, poor absorption, hard water, and uneven coverage. Here’s what each one does and why it matters to your operation:

Why MSO matters

High Surfactant Methylated Soy Oil (MSO) helps herbicides penetrate tough leaf surfaces by softening the waxy cuticle layer on plants. This allows the herbicide to move inside the plant, where it can do its job.

Bonus: It reduces drift and keeps the spray on target, saving you money and effort.
Use it for: Herbicides that require oil or work better with added MSO.

Why leaf wetting matters

Ever sprayed a field and watched your solution bead up and roll off leaves? Lumber fixes that by improving how the spray sticks and spreads.

Bonus: It penetrates plant tissue, getting the herbicide where it needs to be for maximum impact.
Use it for: Glyphosate and other herbicides that require precise absorption and coverage.

Why AMS matters

Hard water can bind up your herbicide, making it less effective. Ammonium sulfate (AMS) solves this by tying up those hard water ions before they can cause problems.

Bonus: The added surfactant ensures the spray spreads evenly and gets absorbed faster.
Use it for: Areas with hard water and herbicides that rely on water-soluble action.

Why canopy penetration matters

If your spray doesn’t reach the bottom of a dense canopy, you’re leaving money on the table. Straight Shot pushes the spray deeper into the canopy while reducing drift, ensuring even coverage from top to bottom.

Bonus: Its antifoam technology makes application smoother and easier.
Use it for: Row crops and dense canopies where complete coverage is critical.

Why wetting and humectancy matter

The longer your spray stays wet on a leaf, the better chance it has to be absorbed. Tiebreaker keeps the solution from drying too fast, so it has time to do its job.

Bonus: Enhances coverage and helps sprays stick to tough surfaces like waxy or hairy leaves.
Use it for: Broadleaf weeds and challenging weather conditions.

Why drift reduction matters

If your spray drifts into the next field or evaporates into thin air, it’s not helping your crops. Timber minimizes those fine droplets that drift away and keeps your spray where you want it.

Bonus: It improves deposition deep in the canopy without sacrificing coverage.
Use it for: Tank mixes and nozzle setups where drift is a concern.

Why MasterLock matters

MasterLock combines cutting-edge DropTight™ surfactant technology with LockTech™ drift control to help your herbicide stick and spread where it’s needed most. This all-in-one non-ionic surfactant, deposition aid, and drift control agent is designed to optimize pesticide performance, reduce drift, and improve canopy penetration.

Bonus: It increases droplet adhesion and reduces bounce, delivering more active ingredient to the leaf surface for better coverage and effectiveness, even in challenging conditions.
Use it for: Tank mixes, tough-to-spray conditions, and when you need to reduce drift while improving droplet deposition and canopy penetration.

Why Adjuvants Should Matter to You

If your spray isn’t staying on target, spreading evenly, or being absorbed properly, you’re not getting the full value of your investment. Adjuvants make sure your herbicides, fungicides, and pesticides work harder and smarter.
