Treating with 2,4-D . This can provide control of most broadleaf pasture weeds. Apply 

 a half quart to a quart per acre (4 -pounds -per-gallon formulation) of 2,4-D amine or 

 ester when the weed leaves are fully grown. This treatment should be applied before 

 the weeds mature and produce seed. Perennial weeds, such as Canada thistle, will need 

 to be retreated as soon as new growth occurs . 



Using 2,4,5-T, or mixtures of 2,4,5-T and 2,4-D . This may be necessary to control some 

 species of brush and weeds. 2,4,5-T is still registered for use on grass pastures. 



Following the grazing restrictions . Be sure to do this when using any herbicide. Keep 

 dairy cattle out of pastures treated with 2,4-D for seven days after application, and 

 do not graze dairy cattle on pastures treated with 2,4,5-T for six weeks. Beef cattle 

 should not be allowed to graze on pastures that have been treated with 2,4,5-T within 

 two weeks of slaughter. Restrictions on grazing areas treated with Banvel depends on 

 the rate. Check the restrictions on the label. 



Applying amitrole and Tordon . They are not registered for use on pastures. 



All of the herbicide treatments listed in this section will injure forage legumes as 

 well as controlling broadleaf weeds. Use these treatments on only grass pastures or 

 where injury to the legume is permissible.
