Detection of bromacil herbicide in ponderosa pine

Bulletin of Environmental Contamination and Toxicology, 1981
Bromacil is a substituted uracil herbicide, 5-bromo-3-sec-butyl-6-methyluracil. Because it is readily absorbed through the root system of plants, bromacil usually is applied to the soil as an aqueous solution or suspension during or just before periods of active plnt growth.

Persistence and mobility of bromacil in orchard soils

Weed Research, 1975
Summary: Résumé: ZusammenfassungBromacil was applied annually for 6 or 7 years in two apple‐orchard experiments. At intervals of a year after the last applications, concentrations at various depths down to more than 1 m were measured by gas‐liquid chromatography.

Sorption of Bromacil, Chlortoluron, and Diuron by Soils

Soil Science Society of America Journal, 1986
Abstract Sorption of bromacil (5‐bromo‐3‐ sec ‐butyl‐6‐methyluracil), chlortoluron [3‐(3‐chloro‐4‐methylphenyl),1,1‐dimethylurea], and diuron [3‐(3,4‐dichlorophenyl)1,1‐dimethylurea] by soils containing contrasting organic carbon (OC) content was studied.

Antagonistic Effects Between Picloram and Bromacil with Oats

Weed Science, 1972
Combinations of 4-amino-3,5,6-trichloropicolinic acid (picloram) and 5-bromo-3-sec-butyl-6-methyluracil (bromacil) pellets applied to the soil gave antagonistic responses on oats(Avena sativaL. ‘Clintland 64′) with either 5.6 plus 11.2 kg/ha or 11.2 plus 11.2 kg/ha of picloram plus bromacil.

Chlorination of bromacil: Kinetics and disinfection by-products

Separation and Purification Technology, 2019
Abstract Bromacil, a nonselective uracil compound, is applied to field crops, such as citrus and pineapple, to control annual and perennial grass weeds. In this study, the degradation kinetics and effects of influencing factors on the formation of disinfection by-products (DBPs) during bromacil chlorination were investigated.

Soil Water Potential and Bromacil Uptake by Wheat

Weed Science, 1975
The uptake of14C labeled bromacil [5-bromo-3-sec-butyl-6-methyluracil] by wheat plants (Triticum aestivumL. ‘Gaines’) grown in a Woodburn silt loam was studied at soil water potentials of −0.35 and −2.50 bars, and in solutions containing 2.0 and 4.5μg/ml bromacil.

Leaching of Terbuthylazine and Bromacil Through Field Soils

Water, Air, and Soil Pollution, 1999
A field experiment was designed to provide data on the effect of soil heterogeneity on the distribution of herbicides following leaching by irrigation and rain water. Terbuthylazine and bromacil, two nonconservative herbicides, together with CaBr2, a conservative chemical, were used in the reported experiment.

Mechanistic Investigations Concerning the Aqueous Ozonolysis of Bromacil

Journal of Agricultural and Food Chemistry, 1997
Bromacil ozonolysis was examined to determine the mechanism of product formation in an effort to optimize a chemical-microbial remediation strategy for contaminated waters. Two debrominated products, 3-sec-butyl-5-acetyl-5-hydroxyhydantoin (II) (24%) and 3-sec-butylparabanic acid (III) (56%), and a dibromohydrin, 3-sec-butyl-5,5-dibromo-6-methyl-6 ...

Bromacil and Picloram under Southern Upland Hardwoods

Weed Science, 1973
Bromacil (5-bromo-3-sec-butyl-6-methyluracil) was much more effective in killing post oak (Quercus stellata Wangenh.) and blackjack oak (Q. marilandica Muenchh.) trees than 4-amino-3,5,6-trichloropicolinic acid (picloram) when applied to soil at 5.6 and 11.2 kg/ha in spots, bands, or by broadcasting.

Dye‐Sensitized Photooxidation of Bromacil in Water

Journal of Environmental Quality, 1980
AbstractIrradiation of an aerated bromacil (3‐sec‐butyl‐5‐bromo‐6‐methyluracil) aqueous solution (250 ppm), by exposure to direct solar radiation in the presence of different dye‐sensitizers and an appropriate pH, led to complete and fast photodecomposition of the title compound. The photoreaction mixture spotted on TLC showed one major intermediate, 3‐
