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.
Differentiating Between The Two Varieties
Its important to note that there are two varieties: gray and pink. While both types are active underneath the snow, pink snow mold is more severe. It can invade and destroy grass crowns and roots, whereas gray snow mold tends to only damage the leaf blades of grass. As their names suggest, pink can be identified by its white-pinkish appearance and gray by its white-grayish look.

Apply Calcium To Lower Ph
The right pH balance for lawn soils should range between 6.2-6.8, but that doesnt mean they dont need calcium. Calcium helps the grass to resist diseases , absorb other micro-nutrients, and build strong cell walls. If you test your soil for calcium and it indicates a deficiency, apply calcium immediately.
An Ounce Of Prevention Is Worth A Pound Of Cure
This old adage holds true for lawn care too. One of the best ways to prevent a snow mold situation is by taking care of your turf grass in the late summer months. This means applying fall fertilizer at the proper time and maintaining a healthy length when mowing. Before winter, the lawn should be cut at no more than 3 and no less than 2 tall. Staying within these guidelines will keep your turf plant strong and healthy going into winter.

Can White Fungus Kill My Plants
Strictly speaking, no. White fungus is rarely fatal to your grass. However, if you leave the disease to spread, your grass will look highly unpleasant.
For starters, the white fungus causes the grass to turn brown and wilter. This is mainly because it blocks the sunlight from the grass blades. In turn, this will disrupt the photosynthesis cycle and cause the grass immense stress.
If you happen to have some plants on your lawn, youll quickly see the white funguss detrimental effect on the leaves and fruits. The fruits will change in color and become bland in taste. This is due to the lower amount of sugar because of the disrupted photosynthesis.
Finally, the white fungus can develop something called haustoria. This allows the fungus to latch onto the grass blades and start sucking out the nutrients.
