{"title":"Ascochyta Leaf Blight Fungicides","description":"\u003cp\u003eAscochyta leaf blight is a dramatic but usually temporary foliar disease of Kentucky bluegrass and sometimes tall fescue or perennial ryegrass. Crowns and roots generally remain alive, so affected turf often recovers with new growth.\u003c\/p\u003e\n\u003ch2\u003eWhat to Look For\u003c\/h2\u003e\n\u003cp\u003eLarge irregular areas can turn straw-colored almost overnight. Green leaves are often mixed among blighted leaves, and individual blades die back from the tip with an abrupt pinched margin. Tiny dark fruiting bodies may look like pepper grains in dead tissue.\u003c\/p\u003e\n\u003ch2\u003eWhy It Develops\u003c\/h2\u003e\n\u003cp\u003eOutbreaks often follow cool rainy weather and then become visible during hot, dry conditions. Uneven soil moisture, irrigation gaps, waterlogging, dull mower blades, mowing wet turf, and excessive spring nitrogen can increase stress and wounding.\u003c\/p\u003e\n\u003ch2\u003eReduce Disease Pressure\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCorrect irrigation uniformity and avoid rapid swings between saturated and dry soil.\u003c\/li\u003e\n\u003cli\u003eWater early so the canopy dries quickly.\u003c\/li\u003e\n\u003cli\u003eSharpen mower blades and avoid mowing wet or severely wilted turf.\u003c\/li\u003e\n\u003cli\u003eReduce mowing frequency during recovery and avoid excessive spring nitrogen.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat University Research and Extension Guidance Says\u003c\/h2\u003e\n\u003cp\u003eColorado State guidance reviewed in 2025 emphasizes cultural recovery because outbreaks are sporadic and fungicide timing is difficult. Nebraska reported that several fungicide applications to an active ryegrass outbreak had not produced a visible benefit. These findings support accurate diagnosis and stress correction before treatment.\u003c\/p\u003e\n\u003ch2\u003eChoosing and Using a Fungicide\u003c\/h2\u003e\n\u003cp\u003eUse the products below as a starting point, then match the active ingredient, FRAC group, turf species, use site, timing, rate, interval, and watering directions to the current product label. Preventive or very early applications are usually more reliable than rescue treatments after extensive injury. Rotate effective FRAC groups and combine fungicides with the cultural changes above.\u003c\/p\u003e\n\u003cp\u003e\u003csmall\u003e\u003cstrong\u003eResearch and label note:\u003c\/strong\u003e University research may identify useful activity even when a current product label does not name this disease.
