Decomposes on heating. This produces toxic fumes including hydrogen bromide and nitrogen oxides. Decomposes on contact with acids or oxidants.

Stable to 0 deg F, but water-soluble formulations become less soluble with exposed to air.

Active ingredient and dry formulations are non-flammable; the liquid formulation (HYVAR-XL) is a combustible mixture which should be kept away from heat and open flame.BROMACIL is incompatible with the following: Strong acids (decomposes slowly), oxidizers, heat, sparks, open flames (NIOSH, 2016).

AEROBIC: The microbial degradation of bromacil in aerobic soil is slow with a half-life of 275 days in silty clay loam soil incubated for up to 12 months. Carbon dioxide was the major degradate with 5-bromo-6-methyluracil, 5-bromo-3-(alpha-hydroxymethylpropyl)-6-methyluracil, 5-bromo-3-sec-butyl-6-hydroxymethyluracil, 5-bromo-3-(2-hydroxy-1-methylpropyl)-6-methyluracil and 3-sec-butyl-6-methyluracil found as minor metabolites(1). Bromacil was degraded within 4 to 6 months when single applications were made to soil; however, when two applications were used, bromacil persisted in the top 75 mm of soil for nearly a year(2). The mineralization half-life of (14)C-labeled bromacil, incubated in loamy sand and mucky peat soils, was estimated to range from 5,429 to 46,200 days(3). Bromacil estimated half-life is 12-46 days in two New Zealand soils; Motupiko silt loam (pH 5.7, 24% sand, 57% silt, 19% clay, 2.4% organic content) Waikiwi silt loam (pH 5.5, 7% sand, 69% silt, 24% clay, 3.9% organic content)(4).

The bioconcentration of bromacil in bluegill sunfish (Lepomis macrochirus) was studied over a 28-day period using flow-through conditions(1). Bluegill sunfish exposed to 10.6 ppm bromacil had BCF values for muscle, viscera, carcass, and whole fish of 49, 72, 22, and 26.5, respectively(1). At 1.0 ppm, maximum BCF values were 4.6, 8.3, 2.2, and 2.8 for muscle, viscera, carcass, and whole fish, respectively(1). Depuration was rapid, with >96% of the accumulated residues eliminated from the fish tissues by day 3 of the depuration period. A BCF of 3.2 was measured in fathead minnow(2). A log BCF of 0.35242 in bluegill sunfish exposed for 28 days has also been reported(3), corresponding to a BCF of 2.20(SRC). According to a classification scheme(4), these BCF values suggest that bioconcentration in aquatic organisms is low. [

Bromacil is very mobile in sand, sandy loam, clay loam and silt loam soils; aged bromacil residues are very mobile in silt loam soils(1). Extensive data exists as evidence that bromacil leaches to ground water as a result of normal agricultural use(1). An average Koc value of 23 was determined from experimental values determined in 8 soils and 4 sediments(2). Koc values of 25 to 50 for for Israeli soils(3), 55 to 126(4), 46 to 93 for 7 sandy Florida soils(5), and 76 to 129 for a mucky peat and a loamy sand Oregon soils incubated at temperatures of 4 and 25 deg C(6) have been reported. Koc values in sand (FL), sandy loam (CA), clay loam (MD), and silt loam (DE) were 12, 33, 2.3, and 14, respectively(7). According to a classification scheme(8), these Koc values suggest that bromacil is expected to have very high to moderate mobility in soil. In soil column leaching studies, bromacil readily leached from loess and sandy soils, but was retained in organic-rich soils(6). As the pH increased from 3 to 12, less adsorption of bromacil to Ca-montmorillonite was measured(4). In 7 sandy soils, a rainfall of 20-23 cm displaced over 96% of applied bromacil(5). Koc values were slightly higher at lower temperatures(6). Maximum bromacil concentrations of 1.25 ppm were detected in groundwater (depths of 4.5-6 meters) three months after the herbicide was applied to a surface of Lakeland, FL sandy soil bearing scrub vegetation of small oaks and poor grasses(9). The pKa of bromacil is 9.30(10), indicating that this compound will exist partially in the anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(11). Desorption of bromacil from Cuban soils were reported as 51.98 and 67.00% from a red ferralitic soil and a brown plastic soil, respectively; the specific adsorption constants are 2.89 and 23.9 ug/g, respectively(12). Adsorption coefficients 1.79 and 4.59 for Motupiko topsoil (1-10 cm) and subsoil (40-50 cm), respectively, and 1.57 for Waikiwi topsoil (1-10 cm) have been reported for two Wakefield, Nelson, New Zealand soils. Soil characteristics are as follows: Motupiko silt loam (pH 5.7, 24% sand, 57% silt, 19% clay, 2.4% organic content) Waikiwi silt loam (pH 5.5, 7% sand, 69% silt, 24% clay, 3.9% organic content)(13).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
