The withdrawal is only temporary. I have checked this with DOW as I know at least one person who didn't believe this to be the case when I mentioned it elsewhere.

As you say even if it had been permanent gardeners will need to be careful when purchasing manure for the next couple of years. Grass will already have been sprayed this year and will be entering the silage chain. The chemical when stacked is a potential problems (according to vailable informatin at the moment) for several years to come. Also in seems some farmers don't know that they should no longer be using it so will continue unaware.
