    • Aerial Application of Herbicides for Control of Sand Sagebrush

      Bovey, R. W. (Society for Range Management, 1964-09-01)
      Single aerial applications of 2,4-D; 2,4,5-T; and a 1:1 mixture of the two gave excellent control of sand sagebrush at some locations in western Nebraska. Repeat applications were necessary for best results to kill regrowth the following year. Silvex consistently gave excellent control from a single application.

      Four things must be known to estimate cost of chemical tree treatment: labor performance rates, quantity of material, wage rate, and unit cost of material. Labor and material requirements are related to tree diameter, stand density, and species treated.

    • Herbicide residues and perennial grass on establishment perennial pepperweed sites

      Young, J. A.; Clements, C. D.; Blank, R. R. (Society for Range Management, 2002-03-01)
      Perennial pepperweed (Lepidium latifolium L.) is a creeping rooted exotic weed that has infested native hay meadows, riparian areas and agronomic fields throughout the western United States. This highly invasive species causes major losses in forage quality and creates numerous management problems. On many sites infested with perennial pepperweed, a near mono-culture exist. Sustainable suppression programs require the establishment of a competitive perennial species. You can not establish seedlings of a perennial competitive species without some initial substantial reduction in perennial pepperweed stands through weed control. Because tillage is not feasible with this creeping rooted species, herbicidal weed control is the primary option. Experience has shown, that the massive and extensive root system of perennial pepperweed can not be completely eliminated with one application of a herbicide. This means that repeated applications of a selective herbicide are required after the perennial seedlings of a competitive species are established. Perennial pepperweed is a broadleaf species that is some what susceptible to applications of 2,4-D. Therefore, the choice revegetation species is limited to a perennial grass that is resistant to 2,4-D applications at low rates as a seedlings and moderate rates once established. The saline/alkaline nature of the soils where perennial pepperweed is often found limit the adapted perennial grasses to tall wheatgrass (Elytriga elongata [Host] Nevski). The herbicide chlorsulfuron has been shown to be more effective in initially controlling perennial pepperweed than 2,4-D. We determined that applications of chlorsulfuron at rates sufficient to control perennial pepperweed resulted in herbicidal residues that severely reduced or eliminated the establishment of tall wheatgrass seedlings. Application of 2,4-D at flower budding for perennial pepperweed (June), followed by seeding tall wheatgrass in the fall (October), and application of low rates of 2,4-D over the wheatgrass seedlings the next spring (May), gave the best grass seedling establishment and suppression of the perennial weed.

    • Spotted knapweed and grass response to herbicide treatments

      Sheley, R. L.; Duncan, C. A.; Halstvedt, M. B.; Jacobs, J. S. (Society for Range Management, 2000-03-01)
      Picloram at 0.28 kg ai ha(-1), clopyralid plus 2,4-D at 0.21 kg ai ha(-1) plus 1.12 kg ai ha(-1), or dicamba plus 2,4-D at 0.56 kg ai ha(-1) plus 1.12 kg ai ha(-1) were applied to spotted knapweed (Centaurea maculosa Lam.) at the spring-rosette, bolt, bud, flower, or fall-rosette growth stages in 1991 on 2 sites in Montana. Treatments (3 herbicide treatments, 5 growth stages) were applied in a randomized-complete-block design and replicated 3 times at each site. Effects of herbicides on mature and seedling spotted knapweed density depended upon spotted knapweed growth stage at the time of application and the number of years after application. Picloram consistently reduced mature spotted knapweed density to low levels (5 plants m(-2)), regardless of growth stage, and its effect persisted through 1994. Clopyralid plus 2,4-D applied at the bolt or bud stage reduced spotted knapweed densities similar to that of picloram (95%) at the Avon site, while providing about 50% reduction in density 3 years after application at Missoula. This treatment may provide an alternative to picloram in environmentally sensitive areas. Dicamba plus 2,4-D was most effective when applied during the bud and bolt growth stages, and least effective when applied during the spring- and fall-rosette stages. In most situations, picloram and clopyralid plus 2,4-D provided greater control of spotted knapweed than dicamba plus 2,4-D. Herbicide treatments increased perennial grass biomass from 173 kg ha(-1) in the nontreated controls to 494,880, and 1,309 kg ha(-1) for dicamba plus 2,4-D, clopyralid plus 2,4-D and picloram, respectively.
