BASF Canada is short on supplies of Liberty, a key herbicide used on canola and other crops, due to a lack of sufficient raw materials to make the weedkiller at its Regina plant in Saskatchewan, according to a tweet by Western Producer.

According to the BASF website, the Liberty 200 SN herbicide is suitable for use on canola, corn and soyabeans.

BASF Canada is part of German multinational chemical company BASF.
