Daconil Causes Cancer? Says Who?
Can we substantiate the claim that chlorothalanil is a proven carcinogen? Where?
Most contact fungicides will lose their labels soon. For political reasons, not scientific or medical reasons. Since something like 90+% of all fungicides for turf & ornamental use get sprayed on golf courses, there isn't much point in attempting to pay for the toxoicological testing requirements mandated by the post-Clinton-era EPA.
It is therefor cheaper to drop residential use from the label. It's the money. Not the science.
