How can this weed be eradicated???? We have spent many many weeks over the past 16 years pulling out the weeds by hand (a 4 acre paddock) and get about 90% of it out this way - ensuring we get the bulb as well and pulling out before they flower. However after so many years we dont seem to be making any progress #( Are there any sprays that can be used? Who is the best person to contact to get it done professionally. I contacted the Ag dept and they were not very helpful There are no horses on the paddock at the moment and wont be for another 2 years - perfect time to get it under control! Any advice would be much appreciated!
