Hi, several days ago I used some weed killer on the weeds in my lawn, a couple of days later all the grass around the weeds started to die as well, and it's spreading quickly, my lawn is approx 150 foot by 30 foot and Approx 20% is now brown and dying,

the birds are going crazy, pecking at the infected areas and digging it up, looking online that would suggest the chafer grub but I can't find anything that relates weed killer to chafer grubs or would that just be coincidence??

Im trying to get as much water as I can on the infected areas but that might be the wrong thing to do

Any help appreciated

thanks

Lee
