In a statement the HSE said:
"Evidence has been obtained that the product is not being marketed in the permitted container and is not identical with the UK reference product, both of which are requirements for placing on the market."
The so-called "parallel permit" for Tevday allows it to be supplied only in a 10kg polyethylene-lined paper bag or aluminium foil and paper bag. But the HSE investigation found it marketed in string/twine tied plastic bags inside 15-litre plastic tubs.
"The product as marketed has not been subject to an evaluation to establish if it is safe to use and may present an additional hazard, particularly to users," the HSE statement warned.
Holders of Tevday have until the end of September to return unused stocks to the UK licence holder, AgChem Access of Norwich.
