Quali-Pro Strobe 50WG Broad Spectrum Fungicide — 50% Azoxystrobin 1lb

Systemic Broad-Spectrum Fungal Control for Turf and Ornamentals — 50% Azoxystrobin WG

Disease management on high-value turf and ornamentals demands both preventive protection and curative reach. Quali-Pro Strobe 50WG Fungicide delivers both in a single water-dispersible granule formulation containing 50% Azoxystrobin — the same active ingredient found in Heritage at a fraction of the cost. Azoxystrobin is a Group 11 strobilurin that inhibits mitochondrial respiration in fungal cells, controlling a wider spectrum of turf diseases than most single-mode fungicides available in this class.

Strobe 50WG's systemic uptake allows the active ingredient to move within plant tissue, reaching infection sites that surface-applied protectants cannot access. This makes it effective both as a preventive program fungicide and as a curative rescue treatment when disease symptoms appear. Turf managers report consistent suppression of summer patch, necrotic ring spot, and take-all patch — soilborne diseases that traditional protectants struggle to reach — when Strobe 50WG is applied at label rates with adequate irrigation.

Labeled for golf courses, turf production farms, ornamentals, lawns, and landscape areas around residential, institutional, commercial, and industrial buildings, parks, recreational areas, and athletic fields, Strobe 50WG covers the full spectrum of professional turf and ornamental applications in a single SKU.

Frequently Asked Questions

Is Quali-Pro Strobe 50WG equivalent to Heritage fungicide?

Yes. Strobe 50WG contains 50% Azoxystrobin, the same active ingredient and concentration as Syngenta Heritage 50WG. It is a generic equivalent manufactured by Control Solutions, Inc. and registered for the same labeled diseases and use sites. Turf managers routinely substitute Strobe 50WG into existing Heritage programs to reduce input costs without changing application rates or timing.

Can Strobe 50WG be used as a curative treatment after disease symptoms appear?

Yes. Azoxystrobin's systemic mode of action allows it to move within plant tissue, providing curative activity when applied at early stages of infection. For best results, apply at the first sign of disease symptoms at the higher end of the labeled rate. Strobe 50WG works most effectively as part of a preventive program, applied before or at disease initiation rather than after established infections are widespread.

What is the resistance risk with Azoxystrobin, and how should I manage it?

Strobilurin (Group 11) resistance has been documented in Anthracnose, Brown Patch, and other turf pathogens following repeated use of single-mode programs. Rotate Strobe 50WG with fungicides from FRAC Groups 3 (DMI), 7 (SDHI), or other non-strobilurin modes of action. Avoid applying more than two consecutive strobilurin applications to the same site within a season.

Does Strobe 50WG control Pythium blight?

Strobe 50WG is registered for Pythium blight control and provides activity against this disease. However, for high-pressure Pythium outbreaks or conditions where Pythium is the primary concern, adding a dedicated Pythium fungicide (such as a Mefenoxam or phosphonate product) as a tank-mix partner provides more robust protection than Azoxystrobin alone.

Is this product restricted in any states?

Strobe 50WG cannot be shipped to or used in Alaska. Verify current registration in your state before purchase, as registration status can change.
