Date of Defense 1993-11-15 Availability restricted AbstractThe comprehensive environmental dynarnics of the heterocyclic Benzimidazole fungicides, Benomyl and Thiabendazole was investigated. This included examining their fate and distribution in the terrestrial and aquatic phases of a laboratory microcosm comprised of silty clay loam soil and plants. The soil component cogtituted a major rclocation site, with approximately
45 and 75% of initial Benomyl (recovered as MBC) and Thiabcndazole concentrations being recovered
from the soil component of the microcosm, respectively, while 53 and 27% translocated
into corn plants. The adsorption mechanism/s of these fungicides onto soil components were investigated using silty clay loam, silty loam and sandy soils as well as Ca-bentonite. These studies indicated that both fungicides were adsorbed to the highest degree on silty clay loam, followed by silty loam and sandy soils.
