| Question: | "You will recall from the visit which you paid to my lawn recently that this sward is composed largely of annual meadow-grass and browntop bent. During the course of autumn, yellow patches have appeared and it would appear that it is the annual meadow-grass that is mainly affected. I am enclosing a sample of the affected area and wonder if you could tell me whether a disease is present." |

| Answer/Response: | "The turf sample from your lawn has been examined by our Plant Pathologist and has found that Anthracnose disease is present. This is caused by a fungus called Colletotrichum graminicola. This is not an uncommon disease if conditions are suitable for the development of the fungus. It usually occurs in late summer or autumn and affected plants turn yellow. The youngest leaf on the plant often has a reddish tinge. At the base of the shoots, the black reproductive structure of the fungus can be seen if old leaf sheaths are stripped away. Symptoms often develop in patches but scattered individual plants in a sward can sometimes be affected. Annual meadow-grass is particularly susceptible but the condition sometimes affects other species as well. Anthracnose characteristically occurs when growing conditions are poor, particularly where soil compaction restricts the air supply to the roots and where soil fertility is inadequate. In other words, grass plants, which are weakened or under stress from environmental factors are usually susceptible to this disease. In view of the above, it should be obvious that good management, including adequate fertiliser treatment and measures aimed at improving soil conditions are the best method of control. Fungicides are not normally recommended. In your case, the report following the advisory visit stressed the need for aeration and top dressing as a method of improving soil and in time this should make the incidence of this disease far less likely. Annual meadow-grass is, of course, best regarded as a weed species and gradually reducing this species by management, which favours the more desirable bentgrass, is also important in the long term." |
