Which Type Of Lawn Fungus Is Harming Your Lawn -- And How To Stop It From Spreading

This page listed under lawn care tips

Lawn fungus is a fungus that damages the grass. It can thrive during high rainfall, at which time, the fungus can cripple the entire lawn.

To win the battle against the funguses, it is best to determine their types. Lawn funguses are known in four types, and they are pink snow mold, fairy ring, rust, and slime mold.

The pink snow molds silently thrive on the grass under the snow cover. Their damage begins as soon as wet and deep snow falls on unfrozen ground causing the plant to become harder. When plants are harder than their normal state, they become attractive to snow mold fungus.

The mold is distinguished by its irregular and brown patches of yellow and brown grass, combined with pink of white cottony fungus after a heavy rain, and during a heavy snow cover on hills and banks.

Besides winter, lawn fungus can also develop when nitrogen from Lawn fertilizers is too much.

Fertilizers with high nitrogen should be applied at the proper season, lest the turf grass becomes conducive to breeding of funguses. To get rid of them, it is best not to apply nitrogen in late fall, and mow the grass.

The fairy ring has unsightly rings of dead grass of dark green with brown mushrooms in rare circumstances. The funguses feed on dead vegetation including the old thatch and stumps found beneath the lawn surface.

The fairy rings attack, after a heavy rainfall, by causing the outer ring to turn brown and affect the overgrown patches of the ring. As soon as moisture accumulates in the lawn, the fairy rings begin to thrive.

To annihilate the lawn fungus, the infected area must be dug out to a depth of 2 feet, and extending 1 foot around the infected part. Refill the hole with a good mix of soil and replant the seed for fresh growth.

The lawn’s enemy in late in summer and early fall, the time when weather is still dry and warm is rust, which takes the form of powdery residue on the grass blades. Rust happens when the lawns, or their sections have an overall rusted hue—yellowish orange or reddish brown.

Rust fungus is particularly damaging to bluegrass. It favors heavy dew, and warm and moist weather. The best approach to eradicate it is the use of flowable sulfur fungicide every three to five days or until all the symptoms disappear. Finalize its extinguishing by applying foliar spray, and mow the lawn grass.

The slime mold is a fungus of white to yellow to gray shades. Sticking closely to beads such as leaves, the molds occur during prolonged rainy period and un-mowed grass. To remove them, rake them out or mow the grass.
