Take-all patch can be difficult to eradicate once it has developed. Over time, there may be a build-up within the soil of micro-organisms antagonistic to the take-all fungus, resulting in lower disease levels (a phenomenon known as ‘take-all decline’). In practice, however, it may be better (and certainly quicker) to over-seed affected areas with ryegrass or fescues.
Scarifying the turf with a lawn rake or electric scarifier in autumn will remove thatch and moss and increase aeration. Poor drainage and compacted areas can be alleviated by forking or by the use of a solid-tine or hollow-tine aerator. Ensure that the lawn is growing strongly by applying adequate (but not excessive) fertiliser. The pH of alkaline soils can be reduced by using acidifying fertilisers such as ammonium sulphate.
There are no fungicides available to home gardeners for the control of take-all. Some lawn maintenance companies offer treatment with a professional fungicide, but there is strict legislation controlling the application of professional products to domestic gardens. You will therefore need to satisfy yourself that the company is operating within the law.
