It commonly is spread possibly by mowing equipment or with aeration, a common management technique that pulls plugs of grassy soil out to help the turf get water and nutrients better. “Luckily this fungal disease does not completely kill the grasses.
How do fungi spread?
Fungi spread by forcibly ejecting spores, making their own wind and allowing natural wind and water to spread their spores. Some spores have hair-like parts that help them disperse more easily in water. Some fungi use insects, such as flies, to help them spread their spores.
What causes Moss outbreaks on golf courses?
While poor or undernourished soil is a significant cause of moss outbreaks on golf courses, the reasons the insidious green pest takes root are varied. Moss thrives in areas that receive a lot of moisture, little sun and scant airflow.
How do fungi reproduce asexually?
A part of asexual reproduction, spores germinate and develop into new mycelium, the growing state of fungi, when moisture, temperature and food availability requirements are met under certain conditions. Fungi can grow towards food when they need it.
How do mushrooms disperse their spores?
Some spores have hair-like parts that help them disperse more easily in water. Some fungi use insects, such as flies, to help them spread their spores. For fungi whose habitat is underneath a forest canopy and has little wind, mushrooms are able to create their own wind by letting their moisture evaporate.
What causes fungus on golf greens?
Dollar spot is a fungal turfgrass disease that is caused by the Clarireedia species. Golf greens affected by dollar spot get an uneven playing surface and are repaired very slowly.
Why are diseases so prevalent on golf courses?

How do you prevent fairy rings?
Take these steps to prevent and control fairy ring:Reduce thatch by mowing the grass with a vertical mower and by aerating—removing small soil plugs or cores from the lawn.Remove tree stumps and roots to reduce the amount of organic matter on which the fungus feeds.More items...
What are the disadvantages of living on a golf course?
The most obvious drawback to living on a golf course is the constant activity behind your home if you live directly on a fairway or green. There are busy parts of every neighborhood, but few involve golf carts and a steady stream of people as early as 5 a.m. on every possible day the weather allows it.
How often do golf courses spray?
To the casual observer, spraying greens every one or two weeks may appear to be overkill. However, short spray intervals allow superintendents to observe putting green performance throughout the season and apply products only at the appropriate time to maximize their efficacy.
What happens if you destroy a fairy ring?
The farmer says that he dreamed that he must destroy the barn. Even collecting dew from the grass or flowers of a fairy ring can bring bad luck. Destroying a fairy ring is unlucky and fruitless; superstition says it would simply grow back.

Poorly maintained, drought stressed lawns on light sandy soils are often the most affected and lawns with a heavy thatch buildup are particularly susceptible to the fungus. There is no easy cure for fairy rings. Don't be tempted to try lime, salt, fungicides or other supposed quick-cure remedies.
How do fungi spread?
How Is Fungi Spread? Fungi spread by forcibly ejecting spores, making their own wind and allowing natural wind and water to spread their spores. Some spores have hair-like parts that help them disperse more easily in water. Some fungi use insects, such as flies, to help them spread their spores.
How does evaporation spread fungi?
Fungi that eject their spores can spread them when animals accidentally bump into their fruiting bodies or when raindrops fall on them.
How do mushrooms spread spores?
For fungi whose habitat is underneath a forest canopy and has little wind, mushrooms are able to create their own wind by letting their moisture evaporate. Evaporation creates cool air, which is denser than warm air and has a tendency to spread out.
Can fungi reproduce sexually?
Fungi can also reproduce sexually , producing a spore stalk that bursts when it is fully mature. According to the University of Hawaii at Manoa, spores have been found in high elevations ranging from 10,000 to 71,000 feet. ADVERTISEMENT.
What is the disease on golf courses?
A turfgrass disease that looked like an ink spill on many southern golf courses has been identified and all but blotted out, according to a plant pathologist with the Texas A&M AgriLife Extension Service.
How does inky disease spread?
It commonly is spread possibly by mowing equipment or with aeration, a common management technique that pulls plugs of grassy soil out to help the turf get water and nutrients better.
Why do greens get attacked by moss?
Moss, as well as its cousin algae, is most likely to attack greens that have been stressed because of extreme weather conditions or damaged during maintenance. Moss can work its way into putting surfaces often unnoticed, and once established, can be difficult to control and eradicate.
What is the most common pest that can take over a green surface?
One of the most common invaders is silvery thread moss, which causes unsightly surface conditions and can take over a green if left unchecked. It can even go into a state of dormancy, further complicating successful management. A problem pest. Moss has become an all-too-common problem on putting surfaces recently.
Why is moss encroachment bad?
Other causes of moss encroachment – poor drainage, disease problems, shade, traffic and poor air circulation – represent more challenging issues. “Shade removal around greens, especially the old push up putting surfaces with no drainage, can be a big help in preventing moss and algae,” Mitkowski says.
When to treat moss and algae?
The timing of moss and algae treatments is crucial and varies from region to region. “There seems to be little efficacy if you go out in the middle of the summer and treat for moss in the Northeast,” Mitkowski says. “It’s much better if it’s done during the fall.”.
What is the rule of thumb for grass?
“It’s a general rule of thumb that if you have conditions that give grass the best opportunity to thrive, then you’ll have healthier stands of grass that can resist things like moss and algae, ” Williams says.
What happens when moss moves into the canopy?
When the moss moves into the canopy, it outcompetes grass for nutrients and eventually will crowd out the blades if not eradicated. “Even if it goes dormant, it doesn’t die and can keep coming back in the same area,” he says. “We have seen it take over entire greens.”.
Where does moss grow?

What is golf sand made of?
Golf course sands are different. They are made of round particles “resembling a bucket of balls with large pore spaces between each ball ,” Kidd says. They promote good drainage, and healthy air and water circulation.
Why do you aerate greens?
Aeration comes in when soils are heavily compacted or the turf is thick with thatch. The greens get punched and sanded, and the sand is worked into each aeration hole to improve air and water flow, giving the roots a better chance to drink and breathe. There is, of course, plenty more to the science of sanding.
Why is sanding greens important?
The green might get spongy, or develop brown spots, or become vulnerable to scalping during mowing. Sanding helps protect against all that. That’s not all, Kidd says. Sanding also improves drainage and helps level out the green, creating smooth, consistent putting surfaces, and firm, fast conditions year round.
Do superintendents sand putting surfaces?
Superintendents don’t sand putting surfaces simply to annoy you. They do it for the long-term health of the greens. That’s the gist. But since you’ve been inconvenienced, you deserve to know precisely why.
Is sand good for grass?
They’re made up of angular particles that are meant “to provide strength and structure.”. That’s good for buildings, but bad for grass, as the sand binds together, reducing the air and water flow needed for healthy root growth. Golf course sands are different.
Does sanding help with thatch?
For starters, Kidd says, sanding helps break up thatch, a layer of organic material that builds up over time in the upper root zone. Too much of that stuff is not a good thing. If levels of thatch exceed roughly a half-inch, Kidd says, “the greens will suffer during extremes of drought and wet periods.”.
