does anyone know how to get rid of "red thread" disease in lawns?

Question

I tried several of the products available, is there any one that you have had sucess with?

Answer 1

Greenview makes one with Bayleton that works well. Scotts also makes one that lists red thread but I like the bayleton better because it can also control rust. The important thing about treating a lawn disease is that you need multiple treatments. Its one of the most expensive things that can happen to your lawn. Make sure you use the curative rate and not the preventive rate when you apply it. These products destroy the fungus causing the disease but they do not kill the spores. You need to reapply every 2-3 weeks (read the package for instructions for the product you settle on) so that you can kill the disease "again" when the spores germinate. If you are doing a single treatment you may as well save your time and money because it won't work. Usually 3 treatments will get rid of it.

Also if you have had it for 2 or more years you may want to try a preventive treatment before the disease appears. It's easier and cheaper to prevent it than it is to cure it.

Answer 2

Maintain adequate soil fertility. The actual fertilization rates will depend upon the types of grass(es) grown, soil texture, and the specific rates recommended in your area. Where red thread has been a problem in the past, maintain a soil pH of 6.5 to 7.0.

Avoid overwatering. Do not water the lawn in the late afternoon or evening. Provide good soil drainage. Plant trees
and shrubs far enough apart so that large areas of grass do not remain shaded for long periods during the day and so that dew and other moisture on the grass will readily evaporate. Selective pruning of established trees and shrubs may also help.

You can also try fertilizing your lawn with nitrogen to make certain the lawn isn't nitrogen deficient; prevent prolonged leaf wetness by watering infrequently; provide good soil drainage and encourage air movement; and control thatch development.
