Brown patch or Rhizoctonia solani species is the most common type of fungus in warm-season turfgrasses such as St. Augustine grass and Zoysia. The fungus normally attacks the base of the grass blades close to where the plants meet the soil. As a result, the base of the leaf blades rot and have a distinctive dark shade. You can also sense a decaying smell if you pull out the affected blades and hold them close.

After a while, the problem spreads from the base of the grass blades to the rest of the blades, resulting in reddish-brown patches as the leaves die. With time, these brown patches can extend for up to several feet in diameter, leaving you with an unsightly lawn.

Rhizoctonia may inhabit the soil for a while before causing visible damage to your St. Augustine turfgrass. The fungus can stay inactive in the lawn thatch until conditions become favorable. You may also notice tan-colored lesions on the edges of individual grass leaf blades, each surrounded by brown or purple rings.

The fungi that cause this disease also produce fungal threads that are grayish-white and fluffy in texture. Home Pest Control came naturally. Entomology bug science was part of agronomy studies. Nearly every indoor pest problem starts outdoors. Crossing over to home pest control from lawn spraying was a natural process — the technology, methods, and materials used for home pest control are modifications of the ones used for lawn spraying.
