Applying Fungicides

Applying Fungicides

If fungal problems have overtaken your lawn, you will need to apply a fungicide.

Fungicide products such as Heritage Maxx or Mancozeb are key to fighting this problem. As they are designed to inhibit the growth of fungi and its spores within the soil or plant.

Read the label of these products before use making sure to add the correct amount into your spray tank. Making sure the correct application rate is being applied whilst mixing well.
When applying to your lawn ensure that you get an even spread of application, avoiding overlapping.
