The photodecomposition of bromacil

Archives of Environmental Contamination and Toxicology, 1974
The action of sunlight on dilute (1–10 ppm) aqueous solutions of the herbicide bromacil (5-bromo-3-sec-butyl-6-methyluracil) resulted in the formation of only one detectable photoproduct, 5-bromo-6-methyluracil, in very low yield. The almost quanitative recovery of starting material, even after prolonged periods of irradiation, indicated that bromacil ...

Kinetics of Bromacil Ozonolysis

Journal of Agricultural and Food Chemistry, 1998
Chemical oxidation processes have been used successfully in the degradation of organic pollutants, yet information is limited concerning the kinetic descriptions of the reaction mechanisms. In this study, the kinetics of bromacil (5-bromo-3-sec-butyl-6-methyluracil, a herbicide) ozonolysis was examined.

The banning of bromacil in Costa Rica

Weed Science, 2020
AbstractBromacil was introduced at the beginning of the 1960s for PRE and early POST control of grasses and broadleaf weeds, particularly in citrus (Rutaceae spp.) orchards and pineapple [Ananas comosus (L.) Merr.] plantations as well as in noncultivated areas.

Bromacil in Lakeland Soil Ground Water

Journal of Environmental Quality, 1978
AbstractThe objective of this study was to evaluate the probable magnitude of the problem of the leaching of pesticides into ground water under extreme conditions: a sandy soil low in organic matter, a persistent and mobile herbicide applied at a high rate, plentiful rainfall, and a water table within 6 m.

Uptake of bromacil by isolated barley roots

Environmental Monitoring and Assessment, 1984
A study of bromacil uptake by excised barley (Hordeum vulgare) roots was used to evaluate this procedure as a tool to learn the uptake characteristics of toxic organic chemicals. Bromacil uptake was shown to be a passive process with an uptake rate (at 0.8 mg l(-1)) of 0.64 μg bromacil g(-1) fresh root hr(-1). A Q10 for the process was determined to be
