Q: Should I Water The Grass After Applying The Fungicide
A: It depends on the type of fungicide youre using and what the instructions tell you to do. As a general rule, systemic fungicides should be watered after application because they need water to work properly. By contrast, contact fungicides cannot be watered afterward because the protective layer they provide will be washed off and therefore useless. Always remember to follow the product directions.
How Long Does Fungicide Take To Work
How long fungicide takes to work depends on the severity of the infection and the effectiveness of the fungicide.
Most systemic fungicides need at least 7 days to take effect but then can remain effective for over 25 days. Contact fungicides work immediately but are only effective for 3 8 days or until the protective layer washes off.

Many Lawn Diseases Can Be Controlled With Fall Treatments
Many of the lawn diseases that have plagued homeowners this summer can be controlled effectively through sound management practices and timely application of fungicides this fall.
If leaf spot, melting-out, dollar spot or summer patch were present in your lawn this summer, take preventive measures now to prevent further turf injury and recurrence of disease problems next year.
Cooler fall weather may slow or mask the symptoms of some diseases such as summer patch, but heavier dews will promote leaf spot development. These two diseases will be back next season, perhaps in more severe form, unless corrective steps are taken this fall.
Bipolaris leaf spot and melting-out develop during cooler, wet weather in fall and early spring. The fungi causing these diseases survive the winter in the thatch layer and in infected crowns and roots. One or two fall fungicide applications are recommended to reduce the amount of leaf spot and minimize pathogen carryover through the winter. These fall applications will increase the effectiveness of the fungicide program in the spring.
The best preventive measure is to use leaf spot-resistant cultivars when establishing a new lawn or renovation an old one. A blend of three or more improved Kentucky bluegrass cultivars resistant to leaf spot provides optimum protection against this disease and reduces the possibility of costly fungicide spray programs.
Following are some fall disease management practices:
— Aerify the soil by coring.
How To Apply The Fungicide
Some products might require you to water the lawn and let it dry before applying the fungicide. Others have better results when you apply them during a particular time of the day.
All the products are different so do not imagine that the same rules apply to all of them.
Before utilizing the fungicide, make sure you carefully read the products label and instructions. These should include important details like after which period you have to reapply the treatment, dosage, whether it should be diluted with water , best temperature, and so on.
Depending on the fungicide of your choice, you might also need either a broadcast spreader or a general hose sprayer to apply the fungicide. If you opt for a liquid fungicide that comes into a recipient that should be sprayed by connecting it to the water hose, you wont need any of the tools mentioned above.
Also, when you apply the fungicide, its always advisable to wear safety goggles and gloves and avoid any skin contact. You should also not use the solution near any wells or animal drinking water sources or food.

The success of a fungicide depends on its mechanism of action and fungicidal activity. Primarily, fungicides destroy lawn fungus by damaging their fungal cell wall and cell membranes. They may also inhibit vital cellular processes within the fungus, thereby killing it.
The best fungicides are those that have been designed to incorporate several killing mechanisms as part of their mode of action. This not only makes the fungicide more powerful, but also reduces the risk of resistance and tolerance development.

When To Apply Fungicides
Fungicides cannot heal grass and plants that have already been affected by a fungal disease, but they can stop the disease from growing further or spreading throughout the lawn. Because of this, fungicides should be applied to lawns before fungus grows as a preventative measure.
Farmers, commercial gardeners, and golf courses use disease forecasting systems to ensure fungicides are applied when needed. Their forecasting tools look at local temperature, relative humidity, and leaf wetness to determine which fungicides need to be used.
For homeowners, the local extension office can be a great source of knowledge about disease forecasting. .

How Long Does It Take Lawn Fungus Control To Work
Its important to acknowledge that lawn fungus control products are not going to reverse the damage that has already occurred. Instead, its going to stop lawn fungus in its tracks. This might take around a week to workand you shouldnt see the lawn continuing to get worse after that point.
But you also shouldnt expect it to bounce back. A lot of homeowners mistakenly assume that their lawn will start to look better after treatment and this just isnt the case.
Once the application of fungicide products has stopped the active growth of fungus, then lawn repairs can begin. Generally speaking, one round of aeration and overseeding is often enough to fill in some of the thinned out areas that might have been caused by disease.
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.

Many conditions can cause patches of brown, dead grass on your lawn, but only one gets the official name brown patch. Brown patch disease is a condition caused by a Rhizoctonia fungus usually Rhizoctonia solani. The fungus often appears in mid- to late-summer when the weather is hot and humid. Brown patch is a foliar disease, meaning that it harms the blades of grass but not the crown of the plant or the root system. Grass plants affected by brown patch may recover on their own, without chemical intervention.
Rhizoctonia can affect all cool-season lawn grasses, but it is especially harmful to ryegrass and tall fescue. Kentucky bluegrass and fine fescues can occasionally be affected, but the damage is usually minimal in these species. Brown patch can also affect a variety of warm-season grasses, including St. Augustine grass and zoysiagrass.

The Development Of Different Fungi
The characteristic arrangement of the fungus in the form of charcoal circles results from the fact that the mycelium grows circularly. Its gradually enlarging the area covered. The hat fungi always grows on the edges of the mycelium formed on the enlarging circle.
During the first period of development, the circles may be invisible. They can also reveal themselves as a clump of grasses with an intense green color or a clump of hat fungi. In the later period, the circles of different sizes are observed. They can reach up to several feet in diameter.
This circle of fungus can grow on the lawn for years. It does so until it encounters an architectural barrier such as the wall of a building or environmental factors unfavorable to the further development of mycelium. Sometimes the fungus on the lawn disappears, only to reappear after a year or two.
Hat fungi most often appear on perennial lawns that have not been regularly or properly maintained. Their appearance is favored by the presence of rotting, slowly decomposing organic matter. These can be the remains of uncut mown grass. They are forming the so-called felt and limiting the access of air to the grassroots.
Very often these are also plant residues and pieces of branches that have not been removed from the ground before the lawn is established.
Too Much Fungicide: Lawn Care No
Fungi often develop resistance and/or a tolerance to fungicides. When this happens, the fungicides become ineffective in combating the lawn fungus. This results in homeowners using more and more fungicides on their lawn without getting the fungal disease to go away.
Using too many fungicides on your lawn is bad for the environment. It may also pose a health risk to pets and young children in your home. On top of all that, its likely to burn a hole in your pocket.
Fungicide rotation is the recommended way of fighting lawn disease. Get two or three fungicides with different modes of action. After one or two treatments with one fungicide, switch to the next and keep rotating until your lawn is completely free of disease.
Generally, it is advisable to reapply fungicides every two to three weeks, or as needed. Finally, you should pay attention to local disease forecasting systems to know when to apply protective fungicides, which fungicides to use, as well as how to apply them.
Fungicide application may also be guided by personal experience. If, for instance, your lawn gets a brown patch during summer, start applying fungicides in spring and continue doing so throughout summer to protect your yard.
