[QUOTE="Campground Cattle, post: 32734, member: 195"] Dun I might be wrong on 2-4d have to back and check my book on restricted herbicides. The secret of successful weed control in fields that have been planted to perennial grasses is timeliness. Most winter and summer annual broadleaf weeds can be controlled if the herbicides are applied when the weeds are less than 6 inches tall. If weeds are killed early, competition is reduced and the seeded grasses can make more rapid growth. Ally can be applied at 0.1 oz/acre to the following grasses after the 3- to 4-leaf stage: blackwell switchgrass; blue grama; big, little, plains, sand, ww spar bluestem; buffalograss; green sprangletop; Indiangrass; kleingrass; altherstone, sand, weeping, and Wilman lovegrass; sideoats grama; orchardgrass; Russian wildrye; and bluebunch, crested, intermediate, pubescent, Siberian, slender, streambank, tall, thickspike, and western wheatgrass. Do not use on soils with a pH greater than 8.0 or on legumes. Add a surfactant at 0.25% v/v. To improve the spectrum of weeds controlled add 2,4-D LVE at 0.25 pt/acre. Grasses must be in 5-leaf stage. Some broadleaf weeds have become tolerant to Ally and other ALS herbicides. If Ally, Amber, Finesse, or Glean have been used in the past, ALS-resistant kochia or other broadleaf weeds may be present. Amber at 0.28 to 0.56 oz/acre controls many broadleaf weeds. Use 60 days after emergence of desirable grasses. The grasses should be in 3 to 4-leaf stage. If 2,4-D is added, wait until after grasses are in 5-leaf stage. The following grasses are listed on the label: bermudagrass, big bluestem, little bluestem, smooth brome, buffalograss, sheep fescue, blue grama, sideoats grama, redtop, timothy, and bluebunch, intermediate and pubescent wheatgrass. Do not use on grass/legume mixture. Add surfactant at 0.25% v/v. The possibility of ALS-resistant weeds exists. Banvel plus 2,4-D amine is a good combination if 2,4-D tolerant weeds are present, such as wild buckwheat, triazine-resistant kochia, or ALS-resistant weeds. Apply 0.5 pt/acre of Banvel plus 1 pt/acre of 2,4-D amine for cool-season grasses after the 5-leaf stage.

Buctril 2EC controls many broadleaf weeds and will not injure most grasses after the 3-leaf stage.
