Dylox on Lawn in Subdivision

Dylox is actually Dimethyl Phosphonate. It is an insecticide.
You are right to be concerned. It is a toxic code of 2, with 1 being the worst (poison) and 5 being the least toxic. Some states prohibit use, at least for agricultural applications. Other states are following suit. There are MANY safer alternatives. Frankly, I suspect this lawn company, or at least the supplier, knows this will be banned and is trying to get rid of it (probably for a cheap price) before it IS banned.
ANYWAY, it is troublesome that you cannot get in touch with your association. I suggest you immediately get a petition up, with signatures from your neighbors, to at least put a hold on doing anything until there can be discussion about it. Hand deliver it to your association president. Most of the big lawn product companies, like Scott, have a series of organic/safer products that can be used. There are numerous small companies (and "homemade" products)that work as well, too, but sometimes the bigger "names" are an easier sell to a group. You are in RED ALERT here. Good luck.

Normally Dylox is used for grub treatment and not recommended for large areas.

Here is a link that I found. It is from 2003 but it was very scary!! Print it out and take it to your association president and do something about it!! The best thing I can tell you is to do your research!! Here are a couple of sites I found when I googled it.
