About Thistlex Pro

Outstanding control of creeping thistle and spear thistle
Excellent control of buttercup species even when flowering

Grazing can resume 14 days after application - this may need to be longer if foliage of poisonous weeds, such as ragwort, are present
Rainfast in 4 hours
Excellent grass safety

Apply to healthy, actively growing weeds at the optimum growth stage.
For best results apply when thistles are actively growing and are 150 mm – 300 mm in size.
If the thistles reach flowering stage, top the thistles and spray when 150 mm – 300 mm in size. This helps to achieve optimal root kill.
