USGA Summary Points:Potassium nitrate applications suppressed anthracnose severity compared to all other N sources; whereas, ammonium sulfate applications resulted in the greatest disease severity. Potassium nutrition and soil pH are being investigated as possible mechanisms involved in these N source effects. Three years of trial work indicate that a soluble-N rate of 0.2 lb per 1,000 ft2 every 7 days applied during late spring and summer was optimal for suppressing anthracnose severity. Greater rates of N (0.4 and 0.5 lb per 1,000 ft2 every 7 days) initially reduced disease severity better than lower rates but resulted in the greatest disease severity by the end of each season. Spring topdressing was more effective than autumn topdressing at reducing anthracnose severity. Spring topdressing at 8 ft3 per 1,000 ft2 provided the greatest suppression of disease, regardless of autumn topdressing. Mechanical injury from verticutting does not appear to increase anthracnose severity. Thus, superintendents should continue to use verticutting to manage surface organic matter accumulation without concern of intensifying the severity of this disease.
