Use

Buprofezin gradually decomposes in soils under flooded and upland conditions, with half-lives of 104 and 80 days, respectively. After 150 days, five degradation products are identified as 2-tert- butylimino-5-(4-hydroxyphenyl)-3-isopropylperhydro- 1,3,5-thiadiazin-4-one, 3-isopropyl-5-phenylperhydro- 1,3,5-thiadiazin-2,4-dione, 1-tert-butyl-3-ispropyl-5- phenylbiuret, 1-isopropyl-3-phenylurea, and phenylurea. As minor products, 2-tert-butylimino-5- phenylperhydro-1,3,5-thiadiazin-4-one or buprofezin sulfoxide are found in the flooded or in the upland soils. Since neither formation of 14CO2 nor hydroxylation is observed in the sterile soils, buprofezin seems to have undergone complete mineralization in soils under both conditions through biological transformation by soil microorganisms.
