    The dollar spot infection (Sclerotinia home carp) appears as light brown or straw-colored spots ranging in size from a quarter to the size of a silver dollar embedded in grass, hence the name. 

    How to Get Rid of Dollar Spot 

    Dollar spots can be treated in several ways, from cultural lawn care practices to chemical fungicide treatments. 

    A. Culture Practices

    Try these lawn care practices to stop the dollar spot in its tracks and keep it from sneaking back. Change your watering schedule. Proper watering timing reduces the risk of drought stress, which can spread dollar spots. 

    What to do: Water deeply and infrequently based on your soil moisture, not on a schedule. Stick to the early hours (before 6 am) to avoid long wet spells on cool nights. Reduce thatch by vertical mowing, power raking, or scarifying and aerating.

    This is because the dollar spot fungus, Clarireeda Jackson, feeds on excess straw in your garden. Improve air movement and reduce humidity by pruning or rearranging trees and shrubs and removing unwanted plant debris. 

    Fertilize your lawn with organic or nitrogen fertilizer to help it recover quickly from spot dollars. Do a soil test to determine what nutrients your lawn needs.

    B. Chemical Methods

    Chemical methods are another option to control the dollar spot. Fungicide applications can be used to treat dollar spots, but they are more effective in preventing this lawn disease. 

    Many fungicides can treat dollar spot, but boscalid, myclobutanil, propiconazole, triadimefon, propiconazole, and vinclozolin have proven to be the most effective. When treating a persistent infection, fungicides should be applied at high rates and frequent intervals with even coverage throughout the lawn.

    Note that Dollar Spot develops resistance to fungicides quickly, so vary the fungicide you use frequently to reduce the risk of resistance. 

    How To Repair A Lawn Damaged By Dollar Spot 

    With a little hands-on care, your yard can recover from a dollar spot infection, especially if you were previously healthy and treated the lawn disease quickly.

    Maintaining a healthy lawn through practices that deter dollar spot will keep your lawn growing back strong and green. consider overseeding your lawn with a fresh layer of grass seed.

    The fungus can spread if you walk on it and then move to another part of your lawn, making dollar stain a serious problem if left untreated.

    Dollar Spot can be more serious than it seems. The first appears because the grass disease kills the entire grass plant, often requiring overseeding.

    Dollar spot takes place all through the developing period and is maximum energetic throughout moist, heat days and funky nights. As the disorder progresses, man or woman spots might also additionally be part of wrecking huge patches of garden. 

    It takes place extensively on golfing greens, however, can also be an excessive hassle on lawns developing below dry soil conditions. Turf harm is generally greater than excessive if there may be a deficiency of nitrogen.

    How To Prevent Dollar Stain 

    There are many ways to prevent dollar stains from taking hold in your garden. Some routine lawn care practices and several ounces of prevention in the form of a fungicide can reduce the risk of dollar spot infection.

    Fungicides can prevent dollar spots before the peak season in late spring and early summer. Remember to mix the fungicide you use to prevent resistance development.

    Fertilize your lawn to reduce the risk of low nutrient levels. Dollar spot spreads quickly in nutrient-poor soils, especially soils with low nitrogen levels. So making sure your lawn is nourished will keep the risk at bay. Mow regularly with a lawn mower to keep your lawn healthy. 

    Clean lawn care equipment after each use. Beat and pull your weed early in the morning to reduce dew formation, a key component of buck propagation. This common practice on golf courses can be applied at home. 

    Just be careful not to try to control an active infestation, as whipping and pulling can encourage the spread of the fungal disease.

    Signs of Dollar Spot Fungus

    Knowing what to look for is crucial to both treating and preventing dollar spots. As the name suggests, the first signs can be circular yellow spots the size of an Australian dollar coin. then the lesions become straw-colored with a reddish-brown border. 

    If the grass is well mowed, the patches will sink in and may coalesce into larger, irregular patches. They can be confused with drought damage or fertilizer burn in taller grasses.

    If you’re not sure what’s causing the damage, do an inspection early in the morning after a chilly night or when there’s a lot of dew on the ground and look for fine threads resembling cobwebs or cotton wool, which disappear as the day heats up. This is known as mycelium and is how the fungus spreads from one leaf to another.

    Dollar Spot can also be spread by Gear, Wind, Ground, People, and Animals.

    Best Times To Apply The Fungicide

    The best time to apply the fungicide depends on whether you are using a contact fungicide or a systemic fungicide. 

    It is usually early in the morning before the bees forage and more than 24 hours before. rain is expected. 

    The spray should be allowed to dry, but avoid spraying in windy conditions or conditions that could encourage spray drift in orchards. It may be necessary to spray more than once if conditions favorable to disease persist, but do not use the same product each time.

    Alternate between contact and systemic fungicides, and use mixed-activity fungicides to avoid developing resistance that can render chemicals less effective. Always read the product label and follow the usage instructions and safety precautions. 

    Some fungicides approved for treating lawn diseases may not be used in the home garden. Some fungicides are less toxic than others, but you should always wear gloves, eye protection, and boots, and avoid skin contact when applying chemicals to your lawn or garden. and keep pets off your lawn for at least 24 hours after application.

    Dollar Spot Treatment

    The most effective fungicides on the market (propiconazole and fludioxonil) to eliminate dollar spots on Michigan lawns. For best results, we spray these fungicides several times a year. 

    This ensures each spray covers a large area to eliminate all sources of lawn disease. In many cases, Dollar Spot can leave a sea of ​​empty spaces in infected backyards.

    While they look unsightly, these empty spaces offer an open invitation for insects and weeds to take hold and damage your lawn. With these concerns in mind, homeowners can also count on our team when it comes to overseeding. 

    Planting new grass seeds can eliminate the mottled appearance and introduce healthy new grass that will help crowd out troublesome weeds. There is also a talk about fertilization, too much straw: low nitrogen levels in the soil can be to blame.

    Nitrogen is the main ingredient for plant growth. Without them, the root systems of plants become weak and less resistant to external forces. 

    Boscalid & Flutolanil

    Boscalid and Flutolanil are two fungicides that can effectively treat short-term dollar stains. In the long term, however, the story changes.

    There is a high risk of Dollar Spot adapting to Boscalid and Flutolanil over time. and essentially learn to outwit your control measures. So even if more fungicides are applied, Dollar Spot will still grow. 

    Chlorothalonil And Mancozeb

    Unlike boscalid and flutolanil, chlorothalonil and mancozeb have a low risk of becoming resistant to Dollar Spot. While this bodes well for the long-term stability of the products, the problem is that none of these fungicides are particularly effective, to begin with. 

    While fungicides give the same results over time, those results are usually mediocre. 

    Propiconazole And Fludioxonil 

    Propiconazole and Fludioxonil offer the best of both worlds high efficacy with a  low risk of resistance to lawn diseases. In other words, these fungicides kill dollar spot quickly and effectively, giving it no chance to adapt to and avoid disease control measures. 

    This happens because propiconazole and fludioxonil penetrate the tissues. This provides long-lasting systemic control. from the roots to the tops of the plants.
