Weed Control Challenge

Cereal yield and quality losses from Canada thistle

Canada thistle and sow thistle deliver aggressive in-crop problems for many growers. Capable of producing 14 shoots per square metre, and a root system that extends for 20 feet, Canada thistle can reduce cereal yields by up to 38%* and significantly affect crop quality.
