A few days ago I posted on my blog an update on pest problems in our area; now there’s more to be concerned about, including:
Lawn Pests – Brown Patch – Look for distinct circular patches of yellow-brown colored turf with leaf spots that are surrounded by grey “frog eye” rings. Leaves pull easily out of leaf sheaths. Contact your local Extension Office on recommended fungicide to use. Depending on severity, repeat application may be needed.
Chinch Bugs – I’ve received several reports of heavy infestations, which feed on grass roots, especially St. Augustine varieties. Although the symptoms may be similar to brown patch, they lack the “frog eye” rings and the yellow-brown areas of declining turf continue to increase in size if left unchecked. To check for their presence, fill an empty gallon water jug with 1-2 tablespoons of dish detergent. Pour this mixture around the perimeter of the discolored areas. Wait a minute and look for emergence of this insect pest. If present, treat with appropriate soil insecticide, such as Triazicide or Talstar, which will also control other soil pests, including grubs, sod webworm, etc.
Although not a pest, centipedes and millipedes are also very active feeding on decaying plant tissue. You needn’t worry about these.
All of the problems noted above are due in part to our current weather conditions, (high temp, high humidity, and lots of rainfall).
