Sorption Behavior and Competition of Bromacil, Napropamide, and Prometryn
Journal of Environmental Quality, 1997AbstractGroundwater contamination by pesticides is a problem of major and increasing concern. Detailed field measurements reveal that leaching of pesticides from soils is often faster than predicted using simple models. This discrepancy is likely due to a combination of physical effects (e.g., preferential pathways) and complexities in the chemical ...

Microbial Degradation of 2‐Carbon‐14 Bromacil and Terbacil
Soil Science Society of America Journal, 1974Abstract Studies were conducted to determine the degradation rate of 2.88 ppm 2‐ 14 C bromacil, 3‐ sec ‐butyl‐5‐bromo‐6‐methyluracil, and terbacil, 3‐ tert ‐butyl‐5‐chloro‐6‐methyluracil, in a ...

Science of The Total Environment, 2016
With the wide application of chiral herbicides and the frequent detection of photosystem II (PSII) herbicides, it is of great importance to assess the direct effects of PSII herbicides on photosynthesis in an enantiomeric level. In the present study, the enantioselective phytotoxicity of bromacil (BRO), typical photosynthesis inhibition herbicide, on ...

GROWTH AND STRUCTURAL MODIFICATIONS OF OATS INDUCED BY BROMACIL
Weed Research, 1969Summary. Dry seeds of oat (Avena sativa L.) were placed in various concentrations of bromacil for 4 hr and then placed either on glasscloth which dipped into the herbicide solution, or with the roots in aerated herbicide solution. Root elongation was measured by two methods. Alter various exposure periods, selected portions of the plants were prepared

Numerical analysis of field-scale transport of bromacil
Advances in Water Resources, 1998Abstract Field-scale transport of bromacil (5-bromo-3-sec-butyl-6-methyluracil) was analyzed using two different model processes for local description of the transport. The first was the classical, one-region convection dispersion equation (CDE) model while the second was the two-region, mobile-immobile (MIM) model.

Movement of bromacil and hexazinone in a municipal site
Bulletin of Environmental Contamination and Toxicology, 1991Herbicides provide a convenient means of weed control because of their effectiveness, low cost (relative to alternative strategies) and ease of application. 'Hyvar x'| and ~elpar'| weed killers are very effective broad spectrum herbicide treatments for general weed control in non-cropland amas such as forests, industrial and right-of-way weed control ...

Field Study of Bromacil Transport under Continuous‐Flood Irrigation
Soil Science Society of America Journal, 1991Abstract The transport processes of sorbing chemicals in field soils are poorly understood. This study characterized the leaching behavior of the weakly sorbing herbicide bromacil (5‐bromo‐3‐ sec ‐butyl‐6‐methyluracil) in comparison to Br ‐
