Quali-Pro Mefenoxam 2 AQ Fungicide — 22.5% Mefenoxam 1 Gallon

Quali-Pro Mefenoxam 2 AQ Fungicide - 22.5% Mefenoxam 1 Gallon

Mefenoxam 2 AQ Fungicide targets the oomycete pathogens that cause some of the most damaging root and crown diseases in nursery, greenhouse, and turf settings: Pythium, Phytophthora, Downy Mildew, and Yellow Tuft. At 22.5% Mefenoxam, it's formulated as a low-odor, water-based (aqueous) concentrate rather than the harsher solvent-based fungicides some growers are used to handling.

The 1-gallon size fits nursery, greenhouse, or turf operations managing a defined area where Pythium or Phytophthora shows up on an occasional, rather than constantly recurring, basis.

Key Features & Benefits

• 22.5% Mefenoxam targeting oomycetes — controls Pythium, Phytophthora, Downy Mildew, and Yellow Tuft, a group of pathogens that cause some of the most persistent root and crown losses in nursery and turf settings.
• Low-odor, water-based formulation — the aqueous base is easier on applicators than solvent-heavy fungicide formulations, without giving up systemic activity.
• Protection lasts up to 3 weeks per application — reduces how often a nursery, greenhouse, or turf program needs to reapply during active disease pressure.
• Tank-mixes cleanly with most other fungicides — the aqueous formulation is compatible with combined spray programs, so it can be folded into an existing rotation rather than requiring a separate application pass.
• Multi-setting label — covers nursery, greenhouse, landscape, turf, and tree applications under one product, useful for operations managing more than one of these environments.

Who Should Use This

This fungicide fits nursery and greenhouse growers, turf managers, and landscape professionals dealing with recurring Pythium, Phytophthora, Downy Mildew, or Yellow Tuft pressure, particularly operations that need a product labeled across multiple growing environments rather than a single-use turf-only or nursery-only fungicide.

About Quali-Pro and Control Solutions, Inc.

Quali-Pro is a turf brand of Control Solutions, Inc. The maker is based in Pasadena, Texas. It calls itself a hybrid producer. That means both newer and post-patent formulas. This dual focus drives the Quali-Pro line. A patent eventually lapses on an active ingredient. Control Solutions then formulates its own version. That version reaches golf superintendents and lawn care firms. It also reaches other turf professionals. They pay less than patent-era branded pricing.

Frequently Asked Questions

What pathogens does Mefenoxam 2 AQ actually control?

It's labeled for Pythium, Phytophthora, Downy Mildew, and Yellow Tuft, a group of water-mold (oomycete) pathogens that cause root rot, damping-off, and crown disease across nursery, greenhouse, landscape, turf, and tree settings. These pathogens tend to flare up under wet, poorly drained conditions.

How long does one application protect against these diseases?

Protection typically lasts up to 3 weeks per application, though actual reapplication intervals should follow the current product label and local disease pressure. Growers dealing with sustained wet conditions may need to stay closer to the shorter end of that window.

Can this fungicide be tank-mixed with other products?

Yes, the aqueous formulation is designed to tank-mix cleanly with most other fungicides, letting it fit into a combined spray program rather than requiring a separate application. Always check compatibility and label restrictions for the specific products being combined before mixing a full tank.

Is the 1-gallon size enough for a full growing season?

That depends on your application rate, treatment area, and how often disease pressure requires reapplication under the label's up-to-3-week protection window. Operations with smaller treatment areas or occasional Pythium/Phytophthora pressure often find the 1-gallon size sufficient for a season, while larger or higher-pressure sites should compare cost per application against the 2.5-gallon size.

Is this formulation different from older Mefenoxam products?

The 2 AQ designation refers to this being a water-based, low-odor formulation rather than a solvent-based one. That change makes it more comfortable to handle for applicators without reducing the systemic control the active ingredient provides.
