The recent drought followed by wet weather has stressed our lawns. This can lead to problems. Here are a few pests that may take advantage of your weakened lawn. The first three are fungus diseases while the others are insects. Proper preventive or curative turf medicine should help your lawn through this critical time.
Brown patch creates a slowly enlarging weak or dying spot in the lawn.
It may have a grey border. The best way to control brown patch is by proper management. Use the least nitrogen you can and still have attractive turf. I have noticed brown patch in highly-fertilized centipede lawns. Water only when the soil is dry as outlined below and consider using a fungicide if you have the disease.
