programme, significantly reduces the incidence and severity of the disease. This alternative to the use of iron as a turf hardener is becoming more popular.
Use iron prudently to harden plant cells off and make them less susceptible to disease. Though care must be taken when applying iron in the form of iron sulphate, as swards that are dominated by Annual Meadow-grass tend to have received an abundance of fertilisers that contain a high proportion of ammonium sulphate. High levels of sulphur can lead to ‘black layer’.
Black layer is a deposit of metal sulphide caused by the activity of anaerobic bacteria. The anaerobic bacteria produce hydrogen sulphide which is highly toxic to turf.
Because Fusarium can survive within the thatch layer, it is good cultural practice to minimise this layer through aeration. Monitor thatch levels and aerate to achieve desired levels of oxygen within the sward. Air flow over the turf can also help reduce the incidence of disease. Drainage will help facilitate the flow of moisture away from the surface. Regular topdressing can help dilute existing thatch levels, however, heavy applications of topdressing are to be avoided as this can engender stress which can lead to an outbreak of Fusarium.
Chemical Methods of Control Professional Fungicides
A large array of fungicides has historically been used, although this armoury has been reduced in recent years as products have been taken off the marketplace. There has also been an increase in disease resistance due to the over reliance upon specific groups of fungicides. Therefore, it is useful to adopt a strategic approach when utilising fungicides to derive the best use for what is a relatively expensive resource.
Consider utilising good cultural practice to minimise reliance upon herbicides; the code of practice states that you should ‘ask yourself whether you need to use a pesticide or whether there is another method of control or combination of methods you could use.’
Appropriate use of the correct fungicide, at the most effective time, will minimise the potential damage done by Fusarium. Fungicides target Fusarium at
different stages and use different modes of action.
The practice of mixing different fungicides together to improve efficacy is a subject that deserves separate consideration. Suffice to say that pesticide labels aren’t merely for guidance, but a legal document. It is an offence not to follow the statutory conditions of use of a pesticide. Broadly, fungicides can be categorised in the following way:
Preventative
Preventative fungicides are particularly effective at inhibiting Fusarium before it becomes firmly entrenched. Where a history of disease exists, and the potential for disease is high, preventative fungicides can be used to prevent Fusarium becoming a problem. This can reduce the overall use of fungicides by tackling the disease when relatively low populations exist. These operate within the plant using various different modes of action. Preventative fungicides would include: Heritage Maxx, Instrata, Banner Maxx, Dedicate and Throttle. Medallion is a fungicide that unusually targets the presence of Fusarium on the leaf, in the thatch and in the top of the soil and, therefore, can be used to break the cycle at many points.
Curative
A curative fungicide is a fungicide whose specific mode of action makes it particularly effective at arresting the progress of the disease quickly. Fungicides applied when the first symptoms of disease are evident have been shown to be more effective in disease control than allowing the disease to become established. Treating effectively with an appropriate fungicide will reduce the potential for future outbreaks and limit the need for further applications. Curative fungicides would include: Interface, Chipco Green and Medallion.
Preventative and Curative
Some fungicides provide a blend of active ingredients and, therefore, can be viewed as both a preventative and a curative. These include the following fungicides: Instrata, Banner Maxx, Dedicate and Throttle.
