Best Fungicide For Necrotic Ring Spot

Introduction

I’m going to be honest with you, if your lawn has necrotic ring spot it’s highly unlikely you’ll ever be able to get rid of it. I realize that may not sound very optimistic but the truth is that there are no fungicides on the market for killing this particular fungus. If you really want to learn about how to successfully treat and kill necrotic ring spot then keep reading because in this article I’m going to share with you some basic tips on what it takes

What is Necrotic Ring Spot

Necrotic ring spot is a disease that affects turfgrasses. It is caused by a fungus, which causes lesions on the leaves of plants. Necrotic ring spot can be more common in high-traffic areas, like golf courses and athletic fields where there is frequent mowing or traffic that disturbs the turfgrass.

The most common symptoms of necrotic ring spot are small brown rings with water-soaked margins that usually appear on the leaf blades and occasionally on stems. Sometimes these symptoms will appear as dead spots in the center of healthy turfgrass (Figure 1). The affected areas may be smaller than ½ inch wide but can grow larger over time if not treated properly (Figure 2).

The Best Way to Prevent Necrotic Ring Spot Organically

• Use a good quality organic fertilizer. Organic fertilizers will help your plants thrive, providing them with the nutrients that they need to grow strong and healthy.
• Use a good quality organic soil amendment. When you amend your soil, you are adding more organic matter to it which improves drainage and helps retain moisture while allowing air in so the roots can breathe! It also adds nutrients back into the soil that might have been depleted over time due to repeated plantings or overwatering/overfertilizing issues.*Avoid overwatering or overfertilizing (basically treat them just as if they were humans: give them enough but not too much). If you find out that either of these two things are happening, then fix it ASAP!

The Best Way to Prevent Necrotic Ring Spot Chemically

Fungicides are not the best way to prevent necrotic ring spot. Fungicides can be harmful to your environment, as well as the health of humans. In addition, fungicides are not organic. They are also not the most effective or reliable method for preventing necrotic ring spot due to their potential for resistance development in pathogenic fungi and their potential for harm when used incorrectly by homeowners.

A Simple Phosphorous Fungicide Recipe You Can Make at Home

In a small container, mix together:

• 1 cup phosphorous acid (available at most farm stores)
• 2 cups warm water (no more than 120 degrees F)
• 1 teaspoon dishwashing liquid.

Pour the mixture into a sprayer and apply it to the affected area.

Mycorrhizae fungi are better than fungicides for preventing diseases in grass

Mycorrhizae fungi are beneficial to grass, and can be applied to it. They’re not expensive, and they’re easy to use. You can apply them yourself or have a professional do it for you. In some cases, mycorrhizae fungi can even be sprayed onto the grass as an aerosol spray!

Mycorrhizae fungi are safe for humans, animals, birds—and even other plants! But if you don’t want any of these things on your yard (like maybe if you have only one tree?) then perhaps don’t try this option out just yet…

Conclusion

We hope that you have been able to find some valuable information in this article, and that you will be able to use this information to help your grass resist necrotic ring spot.
