What is the best time of year to treat lawn fungus?
For best results, you should apply fungicide as soon as the disease is diagnosed. For a more preventative approach, applying fungicide throughout the summer months (or when nightly temperatures rise above 60 degrees) can play a key role in the ongoing health of your lawn.
Lawn fungicide or fungus control can be applied to the lawn after brown patch has appeared, but it is best to take preventative action and begin applying fungus control for the duration of the summer months. We recommend beginning lawn fungicide applications when nighttime low temperatures rise to 60°F.
- Correct your watering regime.
- Water in the early morning instead of the evening.
- Remove grass clippings after you mow (otherwise, you'll spread the disease).
- Remove excessive thatch buildup.
- Aerate your lawn every year.
- Mow the lawn regularly.
- Apply a fungicide in the affected area.
Most fungicides can be reapplied every 14 – 28 days, but be sure to read the product label. If you apply the same fungicide many times, your lawn can build up a resistance to the active ingredients. Due to this resistance, fungus may appear in your lawn even if you put down a preventative treatment.
Spray when there is little or no wind. Most often, this occurs in the early morning or near sunset. Spraying at these times may also reduce risk to pollinators.
However, if your lawn was severely ravaged by lawn fungus, it might take several rounds before your lawn is truly looking its best again. Turf disease control only lasts for about 21-28 days, so if conditions persist, you may need additional measures for season-long control.
Armada 50 WDG is widely recognized for its ability to fight off difficult to control turfgrass diseases. This granular fungicide can be watered in with a garden hose for overall effectiveness and controls a wide variety of the most common turfgrass diseases for 21–28 days.
Sure, spores, pollen mold, fungi, seeds, pods, and even acorns are normally carried by mowers from yard to yard. The only realistic way to prevent it is to mow your own lawn with your own mower.
Lawn Fungus Won't Go Away on Its Own—But Green Lawn Fertilizing Can Help.
Lawn fungus thrives in specific environmental conditions and can be triggered by various factors, including: Excessive moisture from overwatering, heavy rainfall, or poor drainage. High humidity and warm temperatures.
Should I water my grass if it has fungus?
Fungus can vary from gray spots to brown patches and it is important to treat right away so that it does not spread throughout your lawn. Fortunately, there are many solutions that can help with this issue. Recommendations: Only water your lawn as much as necessary.
Can You Put Too Much Fungicide on Your Lawn? Yes, you can use too much fungicide on your lawn. Always refer to the product instructions on the amount of fungicide that should be used, as too much can burn your grass or kill good microbes, which will negatively affect the quality of the soil.
In addition to using an anti-fungal product on your lawn, fertilizing can help to prevent future outbreaks of dollar spot fungus.
Treating Fungus
It's recommended that you not mow BEFORE any herbicide application. The weeds will pickup the herbicide better if they are actively growing. When the temperatures drop, and either morning dew or light rains occur they create the perfect environment which can lead to lawn fungus and disease issues.
After application, it can take roughly a week to take effect, and you shouldn't see symptoms continuing to worsen afterward. For particularly bad infections, additional treatments may be necessary. After fungicide stops the active growth of a lawn fungus, you can begin working on lawn repair.
- Large, roughly circular, irregular patches of dry grass that looks dead.
- Thin red hairs or strands extending up from your grass blades.
- Light green or yellow patches.
- Circular, tan spots.
- Thin patches of frayed or discolored grass blades.
Slightly better control may be obtained by a liquid spray fungicide application rather than by a granular application of the same fungicide active ingredient.
If you want to prevent lawn fungus and grub/insect infestations, we suggest applying Jonathan Green Lawn Fungus Control first, then applying Grub & Insect Control second, and water it in immediately.
Indeed, you can apply fungicide and fertilizer simultaneously.
Under adverse circ*mstances, however, such as long rainy seasons, droughts, overwatering, and substandard lawn care, fungi can spread out of control, leaving you with a blighted lawn. The good news is that you can treat many cases of lawn fungus—and prevent future cases—just by following good lawn care practices.
Does aerating your lawn help with fungus?
Cool temperatures and moisture activate fungus spores. This is why it's important to water grass during the day in the fall and spring months. Proper aeration promotes soil drainage, which also helps prevent fungus from activating.
Too much water can cause fungus growth, one of the most noticeable being mushrooms. Also, red/orange coloring on your grass may indicate a type of rust fungus.
Using too much fertilizer can make your grass prone to fungi. Too little fertilizer can do the same. If you are concerned about fungus on your lawn, it may be a good idea to try an organic, slow-release fertilizer.
Fungicides might have best effect when applied in the early morning or at night, according to preliminary research data.
This can be avoided by spraying early in the morning when temperatures are lower and the relative humidity is higher. In addition to the reduced drift hazard from fungicide volatilization early in the morning, drift may also be minimized in the morning hours due of calmer winds and lower convective air turbulence.
