Fungicides | Treatment & Prevention
6 September 2018
Unfortunately, when the conditions are right, usually damp and humid, the fungal disease could appear in your lawn. These such conditions have been common in many areas across Australia in recent months.
When these turf diseases take hold, it is important that you identify and target the disease with an appropriate response quickly.
Fungal related symptoms to look out for:
- Coloured patches or rings in your lawn – yellow, white or brown
- Powdery coatings or threads on the grass blade surface
- Thinned out areas, or areas of wet or slimy-looking turf
- Leaf-blades with irregular discolouration or texture
What causes fungal disease?
The most common reasons fungal diseases occur are:
- Weather conditions, particularly temperature and humidity
- Overwatering and watering at night
- Soil compaction
- Over fertilising or using the wrong type of fertiliser
- Incompatible grass varieties for your area
- Poor mowing habits – mowing too low in particular
Applying Fungicides
If you have a particularly nasty fungal problem, you will need to apply a fungicide.
Fungicides like Heritage Maxx or Mancozeb kill fungi and the spores within the soil or plant by inhibiting their growth.
Add the required amount of product directly to your spray tank and mix well following the mixing rates and application information on the fungicide label.
When applying ensure even application in order to achieve even disease control. Avoid overlapping sprays.
Precautions
- DO NOT apply using spraying equipment carried on the back of the user.
- Wait to enter treated areas until the spray has dried, unless wearing chemical resistant gloves and footwear.
- DO NOT use this product through any type of irrigation system or ultra-low volume spray system
- Make sure you wear the appropriate protective equipment and clothing when using the fungicide as per the label instructions
