Mode of action of organosilicone surfactants in enhancing the performance of Triclopyr herbicide
Triclopyr formulations in the presence or absence of added surfactants were evaluated in relation to optimum control of gorse (Ulex europaeus L.). From a wide range of non-ionic surfactants, superior formulations of triclopyr butoxyethyl ester were selected on the basis of radio labelled uptake and …

Effects of Mid-Rotation Release on Forest Structure, Wildlife Habitat, and Pine Yield
… were examined: aerial imazapyr and basal triclopyr application. Imazapyr measurement plots were installed in nine Piedmont and twelve Coastal Plain plantations operationally released with imazapyr, and triclopyr measurement plots were installed within a controlled fertilization/release …

Ecosystem impacts of tamarisk (Tamarix spp.) management in the Arkansas River watershed, Colorado: effects of disturbance and herbicide residues on passive plant community restoration
… quantify soil degradation rates for imazapyr and triclopyr from six sites in Colorado. A dose response study was then conducted at two of these sites to determine the relative sensitivity of important restoration plant species to the two herbicides. Exponential decay models estimated imazapyr …

Characterizing Oxadiazon Resistance and Improving Postemergence Control Programs for Goosegrass (Eleusine indica) in Bermudagrass (Cynodon spp.)
… topramezone, with or without the addition of triclopyr, controls goosegrass while maintaining commercially-acceptable bermudagrass quality. In field trials, topramezone rate did not significantly affect goosegrass cover at 56 and 70 days after initial treatment (DAIT). All treatments reduced …

Comparison of chemical and manual methods of precommerical thinning oak stump-sprouts
… treatments and application methods. 2,4-D and triclopyr were applied to competing stump-sprouts using stem injection and low volume basal spray techniques. Kerosene, the carrier for the ester formulations, was also tested for its efficacy properties. One growing season following treatment, …

Evaluation of Screening Techniques for Woody Plant Herbicide Development
… as the independent data. Rapid screens using triclopyr produced more statistically significant regressions compared to those involving imazapyr. Significant regressions were produced that could predict field response of several species using both herbicides and either rapid screening …

The effects of fertilization and release on growth, physiology, nutrition, and sapwood quality of young yellow-poplar
… The crop trees were either released, using a 4% triclopyr ester in kerosene basal spray. fertilized with 224, 291 and 243 kg/ha of N, P, and K; released and fertilized, or left untreated. These treatments were repeated in June of 1992. In 1992, treatments were slightly different. Crop trees were …

Even-aged regeneration alternatives for low quality oak hardwood forests in the Virginia Piedmont
… One regeneration alternative included either a triclopyr basal bark spray or hexazinone soil applied spot treatment for releasing loblolly pine at age one. Both release treatments significantly reduced natural regeneration basal area and density when used two years after the herbicide stump …
