The link above gives the details.

     This is just another reason to grow your own compost, at least you would know what you put into it. I have never sold Forefront or heard of it so it must be something that is not used in the landscape or vineyard  industries out here in Calif very much.  But then there are plenty of nasties that out there. Buyer beware of what you buy.

    We are also having problems with Grazon in old hay and manure. I showed some photos of tomatoes at the ADS in Chicago where the manure had been put into the garden area two years before and it was still affecting these plants after 60 inches of rainfall.

    If that herbicide (aminopyralid) is still present in the manure of animals that have consumed forage tainted with the chemical, one would assume it to de detectable in their meat as well.  Scary stuff, it sounds like.

    Thanks for the article link.
