Ragwort Control

Ragwort control requires a strategic approach because this weed is toxic to livestock and spreads rapidly. Here are the main control methods:

Chemical Control Of Ragwort

The best timing for herbicide application is in spring before the plant bolts, or in fall when new seedlings are still rosettes. Chemical control is often considered the most effective method, though chemical spraying needs to be done routinely as ragwort seeds can remain dormant in the soil for up to 15 years 

For grazing areas, treating with a 2,4-D + dicamba combination at 3.5 litres/ha before the end of the month can form part of an eradication programme. Use precision application methods like spot spraying or weed wiping to minimize environmental impact.

Mechanically Removing Ragwort With A Fork

Commonly used management practices include mechanical removal, grazing, pasture management, biological control and chemical control  Manual pulling can work but has limitations - if plants have been pulled out, it will only solve the problem temporarily as the remaining root will produce new shoots.

Cultural methods include the general avoidance of bare ground areas, pulling/levering, cutting, and the use of burners 

Prevention Of Ragwort and Management Of Your Paddocks

The best defense against tansy ragwort is a strong stand of grass. Maintaining healthy pastures prevents ragwort establishment. Avoid mowing after seeds have set, as this can spread the problem.

Important Timing In The Managment of Ragwort

Summer is not ideal for spraying - focus control efforts in spring or autumn when plants are more vulnerable. The timing is crucial for effectiveness.
