Grub Control and reseeding

Post by allin7614 » Fri Sep 23, 2011 7:58 pm

I believe I have a grub problem. Can I apply a grub control agent (Triazicide / Gamma Cyhalothrin) when I reseed. If not, how long after germination should I wait to apply.

By this time of year the grubs have grown pretty large. The best product to use now to kill these larger grubs is one containing trichlorfon (Dylox) such as Bayer Advanced 24 Hour Grub Killer Plus or one containing carbaryl (Sevin). Products containing only gamma cyhalothrin and Triazicide will not work for grub control because they bind with the soil and do not make it down to where the grubs are - so stay away from those.
As far as reseeding, from what I have read, it is better to wait a week or so after applying trichlorfon or carbaryl before you reseed especially if you have a grub problem. These products can take up to 14 days to begin killing the grubs and you want to make sure the grubs are dead before the tender young roots of the new grass begin to grow!
