Footnotes: 1 Actual start date will vary with region. ²Foliar diseases: use a minimum water carrier volume of 2.0 gallons per 1,000 ft² is recommended. Use a flat fan air-induction nozzle that provides thorough plant coverage. ³Plant growth regulation: Apply Primo Maxx PGR at a rate of 0.125 fl-oz per 1,000 ft² every two weeks throughout the growth season. Application rates of Primo Maxx will vary with golf course. 4 Soil-borne diseases: Water- in fungicides with 0.1” irrigation. Watering-in should provide just enough water to move the fungicide off the leaf into the soil. Avoid putting on too much water, especially when the plant roots are near the surface. Make first application when soil temperature reaches 60-65°F at 2-inch depth. Applying sulfur-based fertilizer every two weeks will help reduce summer patch pressure. Do not use a spreader sticker that may prevent movement off the leaves and into the soil.
