General Application:
Interface Stressgard Fungicide should be applied when conditions favor disease development or when disease first appears, unless otherwise noted on the label. Apply with enough water to provide thorough and uniform coverage. Use 0.5 to 10 gallons of water per 1,000 sq. ft. Do not drench. Apply with a properly calibrated sprayer and maintain agitation during spray operations.

Standard Turf Disease Applications:
For dollar spot, brown patch, leaf spot and melting out, rapid blight, and rust, apply 3 to 5 fl. oz. per 1,000 sq. ft. On greens and tees, repeat applications at 14 to 21 day intervals as long as required. On fairways and other turf areas, repeat applications at 14 to 28 day intervals as long as required. For dollar spot control on fairways, use 2 to 4 fl. oz. per 1,000 sq. ft.

Large Patch:
For large patch, apply 4 fl. oz. per 1,000 sq. ft. Make the first application in fall when conditions are favorable for disease development and before symptoms are visible. Make repeat applications in spring as needed on a 14 to 21 day interval.

Fusarium Blight and Necrotic Ring Spot:
For Fusarium blight and necrotic ring spot, apply 7 fl. oz. per 1,000 sq. ft. Use only preventative foliar applications when conditions first become favorable for disease development. Make additional applications as needed at 28 day intervals. Necrotic ring spot is not registered for use in California.

Microdochium Patch:
For Microdochium patch, formerly called Fusarium patch, apply 4 to 7 fl. oz. per 1,000 sq. ft. Repeat applications at 14 to 21 day intervals as long as required.

Snow Mold Applications:
For gray snow mold and pink snow mold, apply 4 to 7 fl. oz. per 1,000 sq. ft. Make one application before lasting winter snow cover. A second application may be made if there is an extended period of cold, wet weather before lasting snow cover. Apply again in spring after snow melt if needed. Envu snow mold guidance also notes Interface Stressgard may be used at 4 to 6 fl. oz. per 1,000 sq. ft. in late fall before snow cover, during a mid-winter thaw, and/or for spring clean-up after snow melt.

Stress and Turf Quality Support:
When used at labeled rates, Interface Stressgard helps protect turf against winter stress, which may aid in faster spring green-up. When applied during spring, summer, or fall, Interface Stressgard Fungicide may result in healthier, greener turf and help mitigate stress from the summer season. Use in conjunction with good turf management practices, including proper fertility, irrigation, mowing, thatch management, and disease monitoring.Additional Disease Control Tank Mixes:
If turf is threatened by additional diseases, Interface Stressgard may be tank mixed with labeled fungicides such as ProStar, Chipco Triton FLO, Chipco Signature Fungicide, or Banol Fungicide according to label directions. For summer stress complex or summer decline, the label lists Chipco Signature Fungicide at 4 to 8 oz. per 1,000 sq. ft. with Interface Stressgard at 3 to 7 fl. oz. per 1,000 sq. ft. For Pythium blight, tank mix with Chipco Signature Fungicide or Banol Fungicide according to the label for the target disease.
