Worried wheat growers who think they will lose their best defence
against wire worms this spring can rest easy.
Lindane, which is now banned from canola production, can still be used

Lindane was never registered for use on canola in the United States,
which has a much smaller canola crop for which chemical manufacturers
often don’t bother to register products.
But because it was an unregistered treatment in the U.S., Canadian
canola shipments into the U.S. were threatened because products
containing unregistered chemicals can be stopped at the border.
The Canadian canola industry asked the PMRA to stop allowing lindane to
be used on canola.
The situation is different for wheat. Lindane is registered in both the
U.S. and Canada for treatment against wire worms in that crop.
That could change. The PMRA is doing a safety review of lindane, but
Richard said any changes to its use will not be made until after the
coming growing season.
“For this year there’s definitely no problem.”
