dc.description At time of writing, Leafy spurge infested over 1.2 millions acres of untilled, non-cropland habitats such as pastures, abandoned cropland, rangeland, roadsides and waste areas. cattle avoid these fields, which reduces natural feeding sites. Leafy spurge chokes out other forage attempting to grow in these areas, also. Leafy spurge cost North Dakota over $14.4 million in reduced herbage production and carrying capacity. A $75 million loss annually to the state in foregone business activity can be attributed to this weed's presence. It is difficult to eradicate. Picloram (Tordon) appeared to be the most effective herbicide against leafy spurge. It is most effective in killing leafy spurge in high flowering time, mid-June, and during regrowth in late August to the first killing frost of October. Varying herbicide absorption rates due to changes in the environment may result in inconsistent leafy spurge control. In leafy spurge, the deepest translocation (travel/flow) of picloram to the roots appeared to be during the true flowering time and carbohydrate stage.
