Quali-Pro Strobe Pro G Granular Fungicide

Protect lawns and golf turf with Strobe Pro G 30 lb granular fungicide. Dual active ingredients control brown patch, dollar spot and other labeled diseases.

Strobe Pro G Granular Fungicide combines 0.31% azoxystrobin and 0.75% propiconazole to manage labeled turf diseases affecting leaves, stems and roots. Its systemic activity and two fungicide groups make it a practical option for preventive disease programs on lawns, golf courses and other labeled turf areas.

The 30 lb bag offers convenient application with a calibrated granular spreader. There is no spray solution to mix, making Strobe Pro G useful for treating individual turf areas or properties without large spray equipment. Depending on the labeled rate, one bag treats approximately 6,000–15,000 square feet.

BENEFITS OF USING THIS PRODUCT

Labeled Use Sites

Landscape use refers to turfgrass; it does not authorize treatment of ornamental shrubs, flowers or food crops.

Target Diseases and Application Rates

Strobe Pro G is labeled for diseases including brown patch, large patch, dollar spot, anthracnose, gray leaf spot, fairy ring, rusts, summer patch, necrotic ring spot, red thread, powdery mildew, Pythium blight and Pythium root rot. The table below summarizes selected disease programs; use the complete label for disease-specific timing, irrigation and rotation instructions.

Bermudagrass restriction: Do not exceed 3 lb per 1,000 sq ft during any 30-day period on any bermudagrass variety. This limit overrides the general rates and intervals below.

Begin preventive treatments before symptoms develop. Large patch requires fall timing before infection or when conditions favor infection. For take-all patch, the label specifies two spring applications and two fall applications, spaced 28 days apart within each season. Gray snow mold also has a two-application program; consult the label.

Coverage Per 30 lb Bag

Coverage is calculated from the 30 lb net contents. Acre rates above use 43,560 square feet per acre. Select the rate for the target disease and turf type, rather than coverage alone.

Spreader Settings

These selected starting settings apply at 3 mph. Calibrate the actual spreader before treating turf; settings do not replace measurement of product output.

Use the current label and equipment instructions for other models or rates. Bellygrinder equipment is excluded.

Application and Use Restrictions

• Annual maximum: 19.2 lb of product per 1,000 sq ft per calendar year.

• Florida bermudagrass greens: Do not apply to bermudagrass golf course greens when temperatures exceed 90°F.

• Fairy ring: If rainfall is not expected, irrigate with at least ½ inch of water within 24 hours after application.

• Resistance management: Rotate fungicide groups and follow all sequential-application limits on the label.

• Excluded uses: Do not use on turf grown commercially as sod, for commercial seed production or for research.

• Animals and nearby plants: Do not graze treated turf or feed its clippings to animals. Prevent granules from reaching apple trees because some varieties are extremely sensitive.

• Application protection: Wear the label-required clothing, chemical-resistant gloves, shoes and socks. Only protected handlers may be present during application. Prevent contamination of water and movement into aquatic habitats.

Read and follow the label supplied with the product. Disease-specific directions, turf limitations and state requirements govern each application.

How much lawn does a 30 lb bag cover?

One bag covers 15,000 sq ft at 2 lb per 1,000 sq ft or 7,500 sq ft at 4 lb per 1,000 sq ft. The correct rate depends on the disease and grass type.

Can Strobe Pro G be used for brown patch and dollar spot?

Yes. Both are labeled targets. Begin preventive applications when conditions favor disease and follow the applicable rate and interval.

Does Strobe Pro G need to be mixed with water?

No. Apply the granules with a suitable calibrated spreader. Irrigation after application depends on the target disease and label directions.

Can it be applied when seeding a lawn?

The label permits use before or after seeding, including germination and emergence, for ryegrass, bentgrass, bluegrass and fescue turf. This does not include commercial seed production.

Is Strobe Pro G a fertilizer or weed killer?

No. It is a fungicide for labeled turf diseases, not a substitute for lawn nutrition or weed control.
