Fusarium in your Lawn

Fusarium (Microdochium Nivale) is a lawn disease that takes hold of your lawn quickly. It starts as small patches of innocuous yellow grass, spreading rapidly to patches of 6-12 inches in diameter. The affected grass will turn from yellow to brown as it dies, and you’ll often see a white cottony slime in the grass, especially at the edges of the fusarium patch.

What Causes Fusarium?

Fusarium spores are in the air all around us – it’s a lawn disease that can take hold at any time. If you’ve got a moist climate with mild temperatures and slow-moving air, your lawn is at risk. Fungus growth is most likely when night-time temperatures are unseasonably high. A malnourished lawn or unhealthy sward is often to blame for a fusarium infection; certain weather conditions can also trigger the fungus.

How we cure fusarium patch

Our approach to treatment depends on the severity of your lawn’s fusarium infection. Lawn diseases can swiftly build up an immunity to fungicides (similar to antibiotic resistance), so we only apply a fungicide in the most extreme cases. To help your grass fight off fusarium naturally, it’s best to improve the health and drainage of your soil with special feed and weed treatments. Aeration and scarification can also help keep the disease at bay. If we need to adjust the pH of your lawn’s soil, we might also use lime or iron sulphate solution.
