Under <br />severe disease conditions use the highest rate and shortest interval corresponding with the application schedule selected from <br />the table below. DO NOT mow or irrigate after treatment until spray deposit on turfgrass is thoroughly dry.

Dichondra leaf spot: Alternaria spp. <br />Gray Snow Mold caused by Typhula spp.: Apply in sufficient water to obtain adequate coverage (2 to 10 gallons per 1,000 square <br />feet). Apply 5 ounces of this product per 1,000 square feet of turf area (13.7 pounds per acre). Application must be made before <br />snow cover in autumn. If snow cover is intermittent or lacking during the winter, re -apply this product at monthly intervals until <br />Gray Snow Mold conditions no longer prevail. In areas where Pink Snow Mold (Microdochium or Fusarium patch) is likely to occur, <br />apply this product at 5 ounces in combination with products containing iprodione at 1.82 ounces active ingredient, per 1,000 <br />square feet of turf area. Read and observe all label directions for products containing these active ingredients. <br />Fusarium (Microdochium) Patch: This product is effective against Fusarium patch only in areas where snow cover is inter- <br />mittent or lacking during the winter. Apply 5 ounces of this product per 1,000 square feet of turf area. Begin applications in late <br />autumn and re -apply at 21 to 28 day intervals until conditions favorable for Fusarium patch no longer prevail. <br />Algal scum: Apply this product at 1.82 to 3.25 ounces per 1,000 square feet on a 7 to 14 day schedule. When colonies of algae <br />are well established, every attempt should be made to dry out the afflicted area. Once dry, spiking or verticutting should be done <br />to enhance turfgrass recovery in conjunction with the use of this product. Several applications of this product at the high rate may <br />be necessary for turfgrass recovery. When environmental conditions are favorable for algae growth, a preventive program with <br />this product will suppress re -colonization of the turf. <br />
