  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: The ultimate biodegradation rate constant of diflubenzuron at 28°C was measured to be 0.037 day-1 in a sandy loam and 0.026 day-1 in muck soil(1) which correspond to half-lives of about 19 and 27 days, respectively(SRC). In the same study, 80-87% diflubenzuron (initial concentration of 10 ppm) remained in sterile soil after 12 weeks; therefore, soil microorganisms play a major role in the disappearance of diflubenzuron(1). Based on several screening tests, the biodegradation half-life averaged 2.4 days using freshwater sediment and 15 days in sterile freshwater sediment(2). Biodegradation half-lives averaged 14 and 32 days using marine-sediment and marine-water, respectively(2). There were no differences in the disappearance of diflubenzuron from sewage water, whether boiled or unboiled; a 14-15% reduction from 0.1 ppm initial concentration was observed immediately following treatment. Reductions of 30% at 6 hr and 42% at 24 hr were probably due to adsorption(3). When applied to a sandy loam soil under aerobic conditions at 24°C, diflubenzuron had half-lives ranging from 2-14 days (depending on soil texture) with the major degradates being 4-chlorophenyl urea and CO2(4); three minor degradates were 2,6-difluorobenzoic acid, 2,6-difluorobenzamide, and 4-chloroaniline(4).

12.3 Bioaccumulative potential

Reported bioconcentration factors for diflubenzuron in bluegill sunfish (Lepomis macrochirus) ranged from 34 to 200 for fillet and 78 to 360 for whole fish(1). According to a classification scheme(2), these BCF ranges suggest the potential for bioconcentration in aquatic organisms is moderate to high. Diflubenzuron depurates rapidly in fish tissue(1); the depuration rate indicates a rapid decrease (99%) of accumulated residues in tissue during a 14-day depuration period.

12.4 Mobility in soil

Diflubenzuron has reported Koc values of 6,790 and 10,600(1). According to a classification scheme(2), these Koc values suggest that diflubenzuron is expected to be immobile in soil. Binding to soil is an important transport process for diflubenzuron based on soil Kd values for sand clay, silty clay loam, silt loam, sand loam, sandy clay loam, clay, clay hydrosoil, and peat hydrosoil of 40, 40, 20, 25, 130, 110, 150, and 3500, respectively(3). Diflubenzuron is classified as relatively immobile in soil based on Rf values were 0.01, 0.07, 0.14, and 0.34 for silty clay loam, clay loam, and two sand loam soils, respectively(3). In field tests, diflubenzuron was not detectable below the 0-15 cm soil depth segment over a 60-day period(3). In water tank studies, diflubenzuron adsorbed to sediment showed no detectable diffusion from the sediment to water over a 204-day observation period(4).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

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.

Contaminated packaging

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.
