| | Phosalone Usage And Synthesis |
| Uses | Insecticide, acaricide. | | Uses | Insecticide; acaracide | | Uses | Phosalone is a organophosphate compouund used as insecticide and acaricide. Phosalone is a weak inhibitor of acetylcholinesterase. | | Uses | Phosalone is used to control codling moth, aphids, beetles and
thrips on fruit trees | | Definition | ChEBI: A member of the class of 1,3-benzoxazoles carrying a [(diethoxyphosphorothioyl)sulfanyl]methyl group at the nitrogen atom, an oxo group at position 2 and a chloro group at position 6. It is an organothiophosphate insecticide. | | Safety Profile | Poison by ingestion, skin contact,and possibly other routes. A cholinesterase inhibitor. Seealso PARATHION. When heated to decomposition itemits very toxic fumes of Cl-, NOx, POx, and SOx. | | Environmental Fate | Plant. Degrades in plants to chlorbenzoxazolone, formaldehyde and diethyl phosphorodithioate (Hartley and Kidd, 1987)
Soil. Ambrosi et al. (1977a) studied the persistence and metabolism of phosalone in
both moist and flooded Matapeake loam and Monmouth fine sandy loam. Phosalone rapidly
degraded (half-life 3 to 7 days) but mineralization to carbon dioxide accoun
Chemical/Physical. Emits toxic fumes of chlorine, phosphorus, nitrogen and sulfur
oxides when heated to decomposition (Sax and Lewis, 1987) | | Metabolic pathway | Photodegradation of phosalone in solvent yields
dechlorinated phosalone. Irradiation in methanol
affords O,O-diethyl-S-methylphosphorothioate and 6-
chloro-3-methoxymethyl-2-oxobenzoxazoline with other
common products. Photolysis of phosalone in the solid
state as a thin film on a glass surface produces a
number of photoproducts including 6-chloro-3-
mercaptomethyl-2-oxobenzoxazoline and its dimeric
disulfide. | | Metabolism | Orally administered phosalone in mammals is rapidly
degraded by oxidation and hydrolysis to give O,O-diethyl
hydrogen phosphorothioate and phosphorodithioate and
6-chloro-2,3-dihydro-2-oxobenzoxazole, which is further
metabolized and excreted in the urine. It is strongly
adsorbed to soil and rapidly degraded with DT50 values
of 1–4 d. | | Degradation | Phosalone is hydrolysed by strong acids and alkalis with a DT50, of
9 days at pH 9 (PM). |
