Controlling roadside noncrop pine in SE Oklahoma using selected glyphosate formulations with and without LI 700 and Milestone VM Plus

Noncrop pine control is a major issue confronting managers of openings along roadsides and in clearcuts.Herbicides containing glyphosate are commonly used for pine control. Traditionally, managers have applied 4 quarts product/acre with inconsistent results. LI 700 is a penetrating non-ionic surfactant that contains lecithin. Selected treatments of Makaze, Accord Concentrate and Accord XRT II, some with and without LI 700 or Milestone VM Plus, were tested for control of loblolly (Pinus taeda L) and shortleaf (P. echinata Mill) pines in southeastern OK. Herbicides were applied at 15 GPA on 10-Jun-08. Plots were evaluated for control on 14- Jun-09. Three glyphosate formulations at 4 quarts product/acre produced dramatically different results exemplifying the state of operations today. All 6-quart and 8-quart formulations provided \u3e89 percent control. Treatments with LI 700 exhibited more control than comparable treatments without LI 700. Adding 4 quarts product/acre of Milestone VM Plus to 4 quarts product/acre of Accord XRT II increased control numerically over Accord XRT II alone. Managers seeking to control unwanted pines while using less product, should consider Makaze (6 quarts product/acre). This treatment required less active ingredient to provide statistically similar pine control as higher rates of glyphosate

Defining the optimal dose of rifapentine for pulmonary tuberculosis: Exposure-response relations from two phase II clinical trials.

Rifapentine is a highly active antituberculosis antibiotic with treatment-shortening potential; however, exposure-response relations and the dose needed for maximal bactericidal activity have not been established. We used pharmacokinetic/pharmacodynamic data from 657 adults with pulmonary tuberculosis participating in treatment trials to compare rifapentine (n = 405) with rifampin (n = 252) as part of intensive-phase therapy. Population pharmacokinetic/pharmacodynamic analyses were performed with nonlinear mixed-effects modeling. Time to stable culture conversion of sputum to negative was determined in cultures obtained over 4 months of therapy. Rifapentine exposures were lower in participants who were coinfected with human immunodeficiency virus, black, male, or fasting when taking drug. Rifapentine exposure, large lung cavity size, and geographic region were independently associated with time to culture conversion in liquid media. Maximal treatment efficacy is likely achieved with rifapentine at 1,200 mg daily. Patients with large lung cavities appear less responsive to treatment, even at high rifapentine doses

Growth Response from Herbicide, Prescribed Fire and Fertilizer Treatments in Midrotational Loblolly Pine: First-Year Results

This study was initiated to determine growth response resulting from the application of prescribed fire and herbicide, with and without fertilizatio.n. In. southeast Texas, herbicide, prescribed fire and fertilizer treatments were applied in m1d:rotat1onal loblolly pine plantations 1.5 years after thinning. Five replications were established at. each of two study sites located on similar soils, aspects and slopes. Half of each replication. was randomly selected and fertilized. Eight treatment plots were established 1n e~ch replication with one of each of the four treatments of control, herbicide, fire, and herb1c1de/flre randomly applied to fertilized plots and one of each of the four treatments randomly applied to non-fertilized plots. Pre-treatment measurements were taken in a 0.04 ha measurement plot nested within each treatment plot. A late season herbicide treatment of. lmazapyr and Arsenal was applied in October 1999. Burning was conducted in early spring of 2000 followed by fertilizer applications of diammonium phosphate and urea. ~osHreatment measurements were taken in December 2000. Growth response and s1gnif1cant treatment differences are presented in this paper
