    Can anybody tell me how to get rid of the brown spots in St. Augustine grass? I just started noticing them a few days ago but they seem to be spreading rapidly.

    I know it's not dog piss at least. I never let them get into this part of my yard. To look at it, it looks like someone soaked their shoes in Roundup and then walked across the yard. At least that's how it looked at first. Now there are additional brown spots to both sides of the &quot;footprints&quot;.

    Gunner,to check for chinchbugs cut the bottom out of a coffee can place it in the ground about 2&quot;(over the new spots).Fill the can with water and keep the water at least 2&quot; above thegrass for about 5 min and see what floats up.The chinch bugs are tiny black/white,young ones will still have some red in them.Happy hunting!!!<p>----------<br>DON<br>LIANNES' MOWING<br><p><font size="1">Edited by: DMC300

    Your brown spots could be due to drought, lack of irrigation coverage in that area, lack of moisture retention due to runoff or inadequate watering. Assuming you are located somewhere in the SE with SA. Needs water. To determine if it is chinch bugs, check the outer, greener portion of the turf as they will have moved outward to suck the juices. Look for insects about ant size with white wings. They can fly short distances to the good neighbor. If you find them treat with a liquid pesticide as granual dursban will not be watered in as required with a coverage problem. Check the sprinkler system.
