1. Identifying Lawn Rust

Lawn rust is a common fungal disease that can affect lawns of all types. It is caused by a fungus that attacks the leaves of grass plants, causing them to develop rust-colored spots. Rust can also cause the grass to yellow and thin out. In severe cases, it can even kill the grass.

Rust is most common in cool, humid weather, and it is often found in areas with poor drainage. It can also be caused by over-fertilization, especially with nitrogen fertilizers.

There are several different types of grass that are susceptible to rust, including perennial ryegrass, Kentucky bluegrass, and fescues. However, some grass varieties are more resistant to rust than others.

To identify lawn rust, look for the following symptoms:

  • Rust-colored spots on the leaves of grass blades
  • Yellowing of the grass blades
  • Thinning of the infected areas

If you see these symptoms, it is important to take steps to treat the rust as soon as possible. Rust can spread quickly, and it can cause significant damage to your lawn if left untreated.

Visual Symptoms

The most common symptom of lawn rust is the presence of rust-colored spots on the leaves of grass blades. These spots may be small and scattered, or they may be large and cover the entire leaf blade. In severe cases, the rust spots may turn black or brown.

Another symptom of lawn rust is yellowing of the grass blades. This yellowing is caused by the fungus that is attacking the grass plant. The yellowing may be confined to the areas where the rust spots are present, or it may spread to the entire leaf blade.

In addition to rust-colored spots and yellowing, lawn rust can also cause thinning of the infected areas. This thinning is caused by the fungus damaging the grass plant’s leaves. The thinning may be slight, or it may be severe enough to kill the grass plant.

If you see any of these symptoms on your lawn, it is important to take steps to treat the rust as soon as possible. Rust can spread quickly, and it can cause significant damage to your lawn if left untreated.

Here are some tips for identifying lawn rust:

  • Look for rust-colored spots on the leaves of grass blades.
  • Check for yellowing of the grass blades.
  • Examine the infected areas for thinning.

If you are unsure whether or not your lawn has rust, you can contact your local Cooperative Extension office for assistance.

Affected Grass Types

Perennial ryegrass is one of the most commonly grown grass types in the United States. It is a relatively low-maintenance grass that is tolerant of a wide range of conditions. However, perennial ryegrass is also one of the most susceptible grass types to lawn rust.

Kentucky bluegrass is another popular grass type in the United States. It is a medium-maintenance grass that is known for its dark green color and dense growth habit. Kentucky bluegrass is moderately susceptible to lawn rust.

Fescues are a group of grass types that are known for their drought tolerance and heat tolerance. Fescues are generally less susceptible to lawn rust than perennial ryegrass and Kentucky bluegrass. However, some fescue varieties are more susceptible to rust than others.

In general, cool-season grasses are more susceptible to lawn rust than warm-season grasses**. This is because cool-season grasses grow best in cool, humid weather, which is the ideal environment for the fungus that causes rust.

If you live in an area where lawn rust is a common problem, you may want to choose a grass variety that is resistant to rust. Some rust-resistant grass varieties include:

  • Perennial ryegrass: ‘SR 4550’, ‘SR 4650’, ‘SR 4750’
  • Kentucky bluegrass: ‘Midnight’, ‘Sapphire’, ‘Midnight II’
  • Fescues: ‘Durar’, ‘Rebel’, ‘Trophy’

You can also help to prevent lawn rust by following good lawn care practices, such as mowing your lawn at the correct height, watering your lawn deeply and infrequently, and fertilizing your lawn according to the soil test recommendations.

Conducive Conditions

Moist, humid environments are ideal for the fungus that causes lawn rust. This is because the fungus thrives in warm, wet conditions. If your lawn is located in a low-lying area or if it is frequently shaded, it is more likely to develop rust.

Poor drainage can also contribute to lawn rust. When water cannot drain away from your lawn, it creates a moist environment that is perfect for the fungus. Poor drainage can be caused by a number of factors, such as compacted soil, a high water table, or a lack of drainage ditches.

Excessive nitrogen fertilization can also make your lawn more susceptible to rust. This is because nitrogen fertilizer promotes the growth of lush, green grass. However, this type of growth can also make your lawn more vulnerable to disease.

Here are some tips for avoiding the conditions that promote lawn rust:

  • Improve drainage: If your lawn has poor drainage, you can improve it by aerating the soil, installing drainage ditches, or raising the level of your lawn.
  • Avoid over-watering: Water your lawn deeply and infrequently, rather than frequently and shallowly. This will help to promote deep root growth and prevent the development of a moist environment that is ideal for the fungus.
  • Fertilize your lawn according to the soil test recommendations: Do not over-fertilize your lawn, especially with nitrogen fertilizer.

By following these tips, you can help to reduce the risk of lawn rust on your property.

2. Treating Lawn Rust

There are a number of effective treatment options for lawn rust, including cultural practices, chemical control, and natural remedies.

Cultural practices are methods of managing your lawn that can help to prevent or control rust. These practices include:

  • Mowing your lawn at the correct height: Mowing your lawn too short can stress the grass and make it more susceptible to disease. Mow your lawn at the recommended height for your grass type.
  • Watering your lawn deeply and infrequently: Watering your lawn deeply and infrequently will help to promote deep root growth and prevent the development of a moist environment that is ideal for the fungus.

  • Avoid mowing your lawn too short: Mowing your lawn too short can stress the grass and make it more susceptible to disease. Mow your lawn at the recommended height for your grass type.
  • Remove thatch from your lawn: Thatch is a layer of dead grass and other organic matter that can accumulate on your lawn. Thatch can create a moist environment that is ideal for the fungus. Remove thatch from your lawn by dethatching it with a dethatching rake or a power dethatcher.
  • Aerate your lawn: Aeration helps to improve drainage and reduce compaction. This can help to create a healthier environment for your grass and make it less susceptible to disease. Aerate your lawn in the spring or fall.

By following these preventive measures, you can help to minimize the risk of lawn rust infection and keep your lawn healthy and beautiful.

Proper Watering

Proper watering is essential for a healthy lawn. Watering your lawn too frequently or too shallowly can create a moist environment that is ideal for the fungus that causes lawn rust.

How often should you water your lawn?

The frequency of watering will vary depending on the weather conditions and the type of grass you have. A good rule of thumb is to water your lawn deeply and infrequently, rather than frequently and shallowly. Deep watering encourages deep root growth, which makes your lawn more tolerant of drought and less susceptible to disease.

How much water should you give your lawn?

The amount of water you give your lawn will also vary depending on the weather conditions and the type of grass you have. A good rule of thumb is to water your lawn until the water penetrates to a depth of 6 inches. You can check the depth of penetration by inserting a screwdriver into the ground. If the screwdriver goes in easily, your lawn has been watered deeply enough.

How to promote good drainage

Good drainage is essential for preventing lawn rust. If your lawn has poor drainage, water can pool on the surface and create a moist environment that is ideal for the fungus.

There are a number of things you can do to improve drainage on your lawn, including:

  • Aerating your lawn: Aeration helps to improve drainage by creating holes in the soil. You can aerate your lawn with a manual or power aerator.
  • Dethatching your lawn: Thatch is a layer of dead grass and other organic matter that can accumulate on your lawn. Thatch can impede drainage and create a moist environment that is ideal for the fungus. Remove thatch from your lawn by dethatching it with a dethatching rake or a power dethatcher.
  • Installing drainage ditches: If your lawn has a lot of low spots, you may need to install drainage ditches to help water drain away from your lawn.

Balanced Fertilization

Balanced fertilization is essential for a healthy lawn. Fertilizing your lawn too much or too little can make it more susceptible to disease.

How often should you fertilize your lawn?

The frequency of fertilization will vary depending on the type of grass you have and the climate you live in. A good rule of thumb is to fertilize your lawn every 4-6 weeks during the growing season.

How much fertilizer should you apply to your lawn?

The amount of fertilizer you apply to your lawn will vary depending on the type of grass you have and the soil conditions. A good rule of thumb is to apply 1 pound of nitrogen per 1,000 square feet of lawn per year.

What type of fertilizer should you use?

There are many different types of fertilizer available on the market. When choosing a fertilizer for your lawn, it is important to choose one that is balanced and contains all of the nutrients that your grass needs.

Slow-release nitrogen sources

Slow-release nitrogen sources are a good choice for lawns because they release nitrogen slowly over time. This helps to prevent the grass from getting too much nitrogen all at once, which can make it more susceptible to disease.

Organic fertilizers

Organic fertilizers are a good choice for lawns because they are made from natural ingredients and do not contain any harsh chemicals. Organic fertilizers can help to improve the soil health and make your lawn more resistant to disease.

Resistant Grass Varieties

Choosing the right grass variety for your lawn is important for many reasons. One important factor to consider is the grass variety’s resistance to lawn rust.
