The Brown Patch Fungus
Have you heard of brown patch fungus? Known as Rhizoctonia solani, it can be a problem for lawns. The growth of this bothersome fungus tends to be accelerated when the weather is warm and humid. Kentucky bluegrass, tall fescue, and perennial ryegrass are some of the cool-season grasses that it particularly enjoys upsetting.
The thing about brown patch fungus is it’s not very picky. It’ll sneak its way into grass plants through any little openings or wounds in the foliage, causing all sorts of trouble. It grows and spreads there rapidly in good conditions.
Ever wondered what causes brown patch? Your lawn can get it if you use too much nitrogen, not enough air, your soil is too squished, you’re drowning it in water, or you’re using an old mower blade. Keep an eye out if your lawn has a lot of thatch or piles of debris.
To tackle a brown patch, you’ve got to spot the signs early. When you catch it early, it’s easier to deal with and stop spreading. Keep an eye out and take care of it ASAP to prevent brown patches on your lawn! Common symptoms of brown patch fungus include:
- The patches are circular or irregular. They are brown or yellowish. They range from a few inches to several feet in diameter.
- Smoky or halo-like rings of darkened grass at the edges of affected patches.
- The grass blades are thinning or wilting in the patches. They may look water-soaked or greasy in humid conditions.
- Fungi cause white or gray growth on grass blades. This happens, especially in humid periods.
You must tell brown patch fungus apart from other lawn issues. The main ones are drought stress, insect damage, and nutrient deficiencies. The brown patch fungus usually affects a lot of turfgrass. It does so in circular or irregular patterns. Other problems may have different patterns or cause damage in small areas. Ask a lawn care expert or extension specialist about the symptoms in your lawn if you’re not sure.
