10 11 See our website for more information Dollar Spot Cultural: Remove surface moisture (switch when dew occurs); encourage morning sunlight penetration; encourage air movement over the surface; ensure appropriate fertility; reduce thatch; aerate surface. Biological: Some biocontrol products have proved effective in reducing potential infection at lower disease risk. Chemical: Effective fungicides are available. Timing of application dictates optimal performance. Preventative use during periods of high disease pressure provides optimal control. Use at the very first signs of disease can control disease but is higher risk and may require recovery period. Management Symptoms Small spots of bleached turf on close mown turfgrass. Spots may coalesce to form large areas of affected turf. White mycelium may be present of affected areas on dewy mornings. Susceptible grass species Fescue, bentgrass and annual meadow-grass. Time of year Summer and Autumn. Turf conditions Low fertility and surface wetness (especially heavy dews).
