| Question: | "Please identify the cause of yellowing annual meadow-grass on this plug of turf taken from the centre of one of our greens, and what can we do to improve matters?" |
|---|
| Answer/Response: | "Our Plant Pathologist has identified the problem as anthracnose disease, caused by the fungus Colletotrichum graminicola. The disease usually appears as yellowing individual annual meadow-grass plants, sometimes the youngest leaf taking an orange/red colouration, although in severe attacks patches of diseased plants can develop. At later stages of disease development, small black pin-head sized sporing structures may be seen at the base of the plant, as the base rots and the plant dies. The disease is favoured by compaction, explaining its appearance in favoured pin areas and around edges of greens where traffic is concentrated and where machinery regularly turns. Low fertility and prolonged soil wetness (possibly due to compaction) also favour the disease. Cultural prevention in the form of regular aeration through the year to relieve compaction is positive management; also look to move pin positions regularly using the entire putting surface, and take machines off the putting surface to turn if possible. In the summer months anthracnose may be discouraged by timely and moderate nitrogen applications, but do not apply fertiliser in the autumn and winter months as this could lead to severe outbreaks of fusarium patch disease. In most cases these preventative treatments will control anthracnose adequately, although in severe cases effective control may only be achieved using a fungicide. The active ingredient chlorothalonil is currently Approved by MAFF for the control of anthracnose in turf. As with any pesticide application you should work within the law with regard to pesticide legislation, carefully following the instructions on the manufacturers label." |
