Dry patch symptoms on fine turf areas are also thought to be associated with basidiomycete fungi.

They can cause rings or patches of yellowed or greened-up turf and may also be associated with slight depressions of the turf surface. Fungal fruiting bodies will not be seen with superficial fairy rings.<\/p>\n\n\n\n<p>In many cases, the presence of these fungi can be confirmed by smelling the rootzone which will take on a characteristic musty smell. Although all fairy rings will start from a single point and increase in size annually, eventually forming recognisable rings, the growth of these rings will not stop unless the fungus hits a solid surface or disturbed ground. As rings grow together (or coalesce), the definite ring pattern will change to become broken rings, arcs or ribbons across the turf surface. <\/p>\n\n\n\n<p><strong>High Risk Situations<\/strong><\/p>\n\n\n\n<ul><li>Presence of tree stumps and other resevoirs of organic matter. <\/li><li>High thatch levels in fine turf.<\/li><li>High organic matter soils.<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><br>Integrated Turf Management Tips:<\/h4>\n\n\n\n<ul><li>Avoid using root zone mixes with high levels of undecomposed organic materials<\/li><li>Reduce thatch by verti-cutting<\/li><li>Pro-active thatch management program<\/li><li>Irrigate deeply<\/li><li>Use nitrogen fertiliser to mask symptoms on some types of fairy ring<\/li><li>Use soil wetting agents\/soil surfactants to help alleviate hydrophobic soil conditions<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Fungicidal Control<\/strong><\/h4>\n\n\n\n<p>On the basis of limited evidence, <a href=\"https:\/\/www.greencast.co.uk\/product\/turf-management\/fungicide\/heritage-0\" target=\"_blank\" rel=\"noopener\">Heritage<\/a> will reduce the effects of Type 2 Fairy Rings.
