Strobe 50WG jug (6 lbs)

Strobe 50WG Broad Spectrum Fungicide

Strobe 50WG is a professional broad-spectrum systemic fungicide containing 50% azoxystrobin for preventative and curative management of numerous turf and ornamental diseases. Its FRAC Group 11 strobilurin chemistry inhibits mitochondrial respiration in susceptible fungi while systemic uptake through plant leaves, crowns, and roots provides protection against foliar, stem, crown, and root diseases.

Strobe 50WG provides the same active ingredient concentration and WG formulation profile as Heritage® Fungicide, making it a cost-effective generic alternative for professional disease-management programs. It is labeled for turf, golf courses, lawns, athletic fields, parks, landscapes, greenhouses, nurseries, ornamentals, conifers, Christmas trees, and commercial rose production, with flexible foliar, soil-injection, drench, and chemigation applications where specifically labeled.

Application Notes

For most turf diseases, apply 0.2 to 0.4 oz of Strobe 50WG per 1,000 sq ft in 2 to 4 gallons of water per 1,000 sq ft at disease-specific intervals generally ranging from 14 to 28 days. Pythium blight and Pythium root rot use 0.4 oz per 1,000 sq ft on a 10- to 14-day interval. Gray and pink snow mold programs may use a single 0.7 oz per 1,000 sq ft application or two 0.4 oz applications according to label directions. Do not exceed 10 lb of product per acre per year on turf.

For ornamentals, general foliar rates are typically 1 to 4 oz per 100 gallons every 7 to 28 days, although individual diseases have specific rates and intervals. Strobe 50WG performs best as part of a preventative disease-management program. Do not rely on it as a universal late rescue treatment. Follow FRAC Group 11 resistance-management directions and rotate or tank mix with fungicides having different modes of action as directed by the label.
