- Anthracnose attacks grass plants (normally only Poa annua) when they are under environmental stress.
- Disease triggered by low nutrition and compaction leading to reduced turf vigour.
- Once disease reaches basal rot stage fungicides are no longer effective for control of disease but should be applied to prevent further attack.
- Turf should have sufficient nutritional input coming into the end of the growing season.
- Using a slow release fertilizer late in the season ensures that adequate nutrition is in the soil to promote a healthy turf.
- Avoid low heights of cut.
- Minimise mechanical cultivation during periods of stress.
- Aerate to relieve compaction and improve oxygen levels.
- Minimise Poa annua population in sward.
- Over-seed with less susceptible varieties.
- Irrigate in the morning to minimise long periods of leaf wetness over night.
- Use penetrant wetting agents to move water through soil profile and to keep surface dry.
- Use fungicides as part of an IPM programme and be aware of causing resistance to one chemical group by its regular use.
