Description of Problem:

• Lawn develops circular spots with green center.

• Damaged area forms a ring shaped.

• Usually during hot summers.

• The size can be from a few inches to a few feet in size.

   

    Cause of Problem:

• This fungus is attracted to the lawn because of the rapid lush new growth of a high nitrogen feed lawn.

• The chemical fertilizer kills off all beneficial bacteria and attracts these harmful bacteria and fungus.

• The root cause of all fungal diseases is dead soil.

• Over fertilized soil, improperly cared for soil, will die and along with it goes the support system needed by lawn to grow healthy and disease free.

• The city water you use has chlorine (usually) added to it to control bacteria in the water. It is this very anti-bacterial water that kills off all beneficials in the soil further adding to the damage caused by chemical usage. Get a good chlorine garden filter or make your own from a good shower filter.

• Get a in-line feeding unit that supplies bacteria back to soil.

   

  
  

    The Organic Solution:

• Take better care of your soil!

• Top dress with compost several times per year.

• Top dress with rock dust several times per year.

• Aerate each time before topdressing is done.

• Composted horse manure makes a good lawn topdressing.

• Avoid using all chemical fertilizers, etc on the lawn.

      Using Compost Tea to control fungus:

1. A good strong compost tea can be sprayed on the effected lawn to control most fungus related problems.

2. Allow the tea to sit for a few days before using.

3. Add some natural ( a few drops per gallon) to increase effectiveness as the soap becomes a wetting agent.

4. Adding Nitron A-35 and Superseaweed to this mixture will greatly improve its effectiveness.
