The Q&A Archives: Dead patches of lawn that is spreading

Question: I have large patches of dead grass which are spreading. I have treated with grub control with merit by Bayer. I just purchased Ortho Bug Be Gone Max for Insects for long season control. Any other suggestions?

Answer: If you've applied insecticides, they should take care of any pests in your lawn. If the insecticides have not stopped the browning, your lawn may have a fungal disease. It's difficult to diagnose without being able to see and handle the lawn so perhaps the best thing for you to do is to take a sample of the lawn (try to cut a portion that has both healthy and brown lawn in it) and take it to your local cooperative extension office for positive identification and suggested remedies for your lawn.
