I have a large, growing dead spot on lawn. How can i stop it?
Question:It is a small putting green in the back yard. It started as asmall spot then rapidly grew outward -- now about half the green.
Is this disease? bugs? any ideas?
Answers:
It could be any number of things causing your dead spots but it sounds like lawn fungus. Check out this site: http://pestproducts.com
anything could be effecting it you need to take up the dirt and replace it then reseed it
It is most likely bugs. If you turn over just the very top of the dead grass/dirt you should be able to see ants or slugs. If so then you can treat the lawn to get rid of them. You can also buy packages of grass seed and fertlizer that are used just to fill in the dead spots so you don't have to seed the whole lawn. The main thing though is to isolate the problem first. We had this same problem and it was bugs that caused the problem. I don't know much about diseases that could cause this. Maybe someone else will. Good luck.
It could be several things, such as, a lawn fungus, Scotts makes a fungus control product that cures and prevents fungus from forming. Or it could be insects destroying it such as grubs, ants, etc. Try Grub Ex, or a Big B GON product. Good luck!
grubs.need to put down an insecticide
Probably fungus.Mole crickets may be a factor but they are the Hienas to the fungus ' kill.Did you fertilize in early spring (or even late fall?) Lawn fungus thrives on nitrogen. When a high nitrogen fertilizer (such as weed and feed) is applied to an area where a fungi is present, it is as if someone threw fuel on a fire. If this has happened to your lawn, you need to immediately treat the area with a good fungicide. Cheap fungicides might stem the tide a little but by using them you run the risk of losing your lawn to a fast moving fungus.When living in an area where molecrickets are a known pest, do not be too quick to blame molecrickets for lawn problems that occur in late winter or early spring - times that we know are too early for molecricket attacks.
Examine the damaged areas carefully. You need to know if the damaged area are expanding. Are the areas active or dormant?
Prevent lawn fungus problems with good cultural practices. Do not use too much nitrogen on the lawn when conditions are right for development of fungus.
Use a systemic fungicide at low, preventative rates to save money in the long run. Once you have a problem, it takes twice as much fungicide and two applications have to be made at two week intervals. Curing a fungus costs four times more than preventing a fungus problem in lawns.Good luck!
