Persistence and degradability
Mixed cultures from soil and water were able to use benomyl as a sole carbon source but the degradation rate was slow(1). A proposed pathway for the bacterial degradation of benomyl proceeds by 2-aminobenzimidazole(1). Strains of Psuedomonas were isolated from soil and water that could grow on a mineral salts medium with benomyl as the sole carbon source(2). In another study, four strains of bacteria and 2 of fungi, which decomposed benomyl to non-fungistatic compounds, were isolated from loamy garden soil(3). Decomposition (16-34%) of 14C ring-labeled benomyl, during 6 and 12 months incubation periods, occurred only in nonsterilized soil. Ring cleavage of the benzimidazole nucleus and metabolism of this moiety to CO2 is apparently related to the presence of microorganisms(4).
Bioaccumulative potential
An estimated BCF of 9 was calculated for benomyl(SRC), from a log Kow of 2.12(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Mobility in soil
In a field study on the fate of benomyl applied to bare soil and to turf, benomyl and its degradation products showed little or no downward movement through the soil (Keyport silt loam, Cecil loamy sand, and Leon Immokalee fine sand)(1). Lab and greenhouse experiments showed that benomyl and its two soil metabolites, methyl 2-benzimidazole carbamate (MBC) and 2-aminobenzimidazole (2-AB), were immobile in soils (organic matter ranged from 0.7 to 83.5 percent) and did not leach or move significantly from the site of application(2). The Koc of benomyl measured in soil is 2,000(3). According to a classification scheme(4), this Koc value suggests that benomyl is expected to have slight mobility in soil(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
