Fungicides are used to correct and prevent fungus from damaging turf. There are 2 common rates. Curative: cures a current fungus problem. Preventive: prevents a fungus problem. It is best to only use a fungicide with 1 Mode of Action (MOA)/FRAC Group no more than two consecutive applications. Resistance to fungicide is a real problem and we don't want to add to this problem. Therefore, it is best to combine 2 or more fungicides on a rotation or even in 1 application. This list is for fungicides approved for residential use. There are many other very effective fungicides but they are not labelled for residential use. Always wear protective clothing per the product label.

- The italics are products which may be available in local home improvement stores.
- Granular products can be spread using a fertilizer spreader.
- Fungus in red generally has excellent control, green has good control, blue is ok control, and black is unknown regarding efficacy.
- The $ sign is for the cost of one bottle of the product and the # sign is for the cost of application per 1000 sq ft based on a 1-5 scale, 1 being the lowest. Cost is based on preventive rate of BP or the most common fungus it treats and the smallest quantity available. Larger quantities are usually much lower #.
