Take-All patch (Gaeumannomyces graminis) is a turf disease that occurs mid-spring or early autumn.
Conditions which favour the disease include sterile soil conditions (such as newly constructed sand greens), poor aeration, and high alkalinity.
Patches of bronzed Agrostis up to 30cm diameter with centres colonised by fescues, Poa annua or broad-leaved weeds are characteristic. The centres may be slightly sunken. Turf takes a long time to recover. Consequently, all efforts must be directed at preventing outbreaks.
Firstly, recognise the situation in which Take-All patch is likely to occur. Avoid applying lime unless it is absolutely necessary. Ascertain if the water supply has a high lime content. Apply fertilisers containing iron and/or ammonium sulphate to acidify the turf surface. Maintain good turf vigour by maintaining an adequate supply of other nutrients. Ensure the turf is free-draining by regular spiking.
Control is possible with approved fungicides.
