Diagnosing A Disease or Fungal Infection In Your Lawn Turf or Grass

The lawn disease information listed below is simply for self-diagnosing to better understand problem areas in your lawn, grass or turf. If you are experiencing any of these symptoms we highly recommend contacting a Feasel's Lawn Care Expert right away to get a professional opinion before treating any type of fungal infection or lawn disease. An improper self-diagnosis and treatment could potentially harm your lawn even more or create mutations in the disease which could make it immune to certain types of treatment making it very difficult to cure. Due to the nature of lawn diseases and the commonality of their symptoms, identifying the disease visually may be difficult. If our Lawn Care Experts can't diagnosis the problem on the scene we will gather samples and take them back our Disease and Pest Control Lab to further investigate the disease or infection affecting your lawn. You will be provided with a report outlining our findings and we will work to rid your lawn of any and all diseases.
