The Q&A Archives: lawn disease?

Question: My grass is always thick & healthy. Now there are brown patches all over the yard. I used Grubex earlier this year so i don't think it is a grub problem. I usually water Monday, Wednesday & Friday around 5 a.m. for 20 minutes. I also water after i cut the grass on Saturdays.

Any ideas?

Answer: It sounds like it could be a fungal disease called Brown Patch. The disease is favored by excess thatch, high temperatures (75? F - 95? F) high humidity (99 - 100%), excess moisture, and lush growth caused by excess nitrogen. Closely mowed turf are especially susceptible and easily damaged by brown patch. If brown patch is present in the lawn, it will first appear as brown patches in circular patterns a few inches across. As the disease spreads, the affected areas will grow to several feet in diameter. The center of the spots may recover, leaving a ring of infected grass. If this sounds like what is happening with your lawn, you can use a fungicide such as Daconil or Banner.
