This potent aniseed oil based liquid is used for treating wheat or pellets. One litre treats one tonne of food- although since this oil is the strongest on the market- some people mix it with up to five litres of cooking oil to make it go further - it will still smell strongly at this mix. This aniseed oil is one of the best products of its type on the market. It is supplied in a litre bottle. Also available with added Garlic- choose stock code 2167 from the drop down box.
