Editing Fusarium patch (section)

===Chemical controls===
Chemical controls (i.e. the use of [[fungicide]]s) to specifically control turf grass diseases have been around since 1891.  Over the years better controls have been developed, all of which tend to be less toxic to animals and the environment when used properly.

There is a wide variety of chemical groups that are labeled for control of Microdochium Patch. They include, but are not limited to the [[Methyl group|methyl]] [[benzimidazole]] [[carbamates]] (MBCs) such as [[thiophanate methyl]], the [[Dicarboximide fungicides|dicarboximides]] such as [[iprodione]] and [[vinclozolin]], the DMIs such as [[fenarimol]] and [[propiconazole]], the QoIs such as [[azoxystrobin]], [[pyraclostrobin]], and trifloxystrobin, the phenylpyrroles such as fludioxonil, certain [[aromatic hydrocarbon]]s such as [[Pentachloronitrobenzene|PCNB]], and the cholronitriles such as [[chlorothalonil]].<ref>[Nick Christians.2007.

These chemical classes should be rotated so that selection pressure on the disease in limited as to avoid [[Pesticide resistance|resistant]] strains of this disease. The applicator should read and follow all label rates and directions. Breaking these directions and misuse of any labeled product is breaking the law. Remember that the label is the law. The best way to control Microdochium Patch especially going into winter is to use a three way spray right before the first snow fall. A combination of a [[Dicarboximide fungicides|dicarboximides]] such as [[iprodione]], a chloronitrile such as chlorothalonil, and a DMI such as [[propiconazole]] will give sufficient control over the span of an average winter.
