Robbie,
There are quite a few approved fungicides that can be used on private lawns that partiularly address this issue but not cheap.
I have had good results in the past by undertaking aeration to ensure that ground is free draining as possible and applying a balanced feed with approx. 5% (or less) of Nitrogen.
On most residential lawns, if you can manage the thatch level and drainage issues to keep the sward healthy you are half way there. Soil Ph levels also make a difference but how many clients want to take it to that degree?
If you do have to apply a fungicide, you will only need a very small volume and if you have a number of lawns to treat it should work out fairly cost effective.
Up until now I have always used iron sulphate.
As far as I'm aware there are very few products that can be legally sprayed on private lawns / gardens.
There are of course lots of products that you can use on managed amenity sites, but do we fall into that category?

Throttle is another one
You can always speak to ProGreen for advise and guidance.
Here's some info I have on definitions from a couple of PDF's;
From the Pesticide Inspectorate (Italics mine):
a. "Pesticides" means biocidal products intended to protect areas for designated uses, including prevention of the growth of undesired vegetation;
b. "Use of pesticides on amenity areas" means the application of a pesticide to any area which does not bear produce intended for human or livestock consumption or for use as a raw material in any process;
c. "Managed amenity turf" meaning frequently mown, intensively managed turf. This includes turf in public parks, golf courses, and sports fields where the grass is frequently mown;
d. "Amenity grassland" meaning semi-natural or planted grassland with minimal management. This includes minimally managed areas such as found on some railway embankments, motorway verges or embankments, airfields and grassland nature reserves which are not intended for grazing;
e. "Amenity vegetation" meaning areas of semi-natural or planted herbaceous plants, trees and shrubs. This includes vegetation, or an area of land bearing such vegetation and the surrounding soil, it can include small grassy areas mixed with other vegetation. It may also include planted areas such as rose beds, ornamental gardens and tree and shrub plantings, as well as semi-natural areas such as heathland as long as they are not intended for grazing;
f. "Land not intended to bear vegetation" meaning soil or man made surfaces where it is intended that no or minimal vegetation will be grown for several years. This may be bare soil but is often covered by a surface such as gravel, hard-core, tarmac, concrete or railway ballast. It includes public access areas such as pavements and tennis courts, industrial areas such as pipelines, or any other area where no or minimal vegetation is required. Land between rows of crops, between plants in row crops and between trees in orchards is excluded from the scope of the definition;
g. "Green cover on land taken out of production" meaning fields covered by natural vegetation or by a planted green cover crop which will not be consumed by humans or livestock or used as raw materials for any process. This does not apply to land lying fallow as part of a cycle of production.
From The Amenity Forum: MANAGED AMENITY TURF
• Managed amenity turf is defined as „„areas that are frequently mown and intensively managed including fields used for turf production, sports turf and golf greens, tees and fairways‟
• The type of turf used depends on use – so traditionally fine bent/ fescue swards for bowling greens/ golf greens although creeping bentgrass now commonly found, ryegrass/ meadow grass for football pitches etc
Difficult call ? - it is very subjective....but I would say so due to this : "areas that are frequently mown and intensively managed including ......."

You beat me to it Gary! I was going to post up what is everyones definition of amenity turf.
For me on residential lawns, I would always look for a product that states residential lawns or fine turf - easy for lawn fertilisers. Becomes more of a challange with fungicide / herbicide / pesticides but as you mentioned areas that are frequently mowed or other key words such as fine turf and surely you could justify it if it states professional lawn care.
Bottom line, if in doubt, consult your amenity provider for guidance.
Thanks guys

or
