Method for selective determination of phthalophos and phosalone in fish and water. Trondina, G. A. (Vses. Inst. Eksp. Vet., Moscow, USSR). Veterinariya (Moscow), (6), 96-8 (Russian) 1978. CODEN: VETNAL. ISSN: 0372-5669. DOCUMENT TYPE: Journal CA Section: 4 (Toxicology) Phthalophos (I) [732-11-6] and phosalone (II) [2310-17-0] were detd. in water and in tissue samples of fish by thin-layer chromatog. on silica gel plates using a petroleum ether-acetone (9:1) mixt. as the eluting mixt. and bromphenol blue spray (followed by 1% citric acid soln.) as the developing agent. Spraying with 2% 4-aminoantipyrene and then 10% K4Fe(CN)6 selectively identified II. Chromatog. on Silufol plates was sensitive for the 2 pesticides in concns. of 0.005 mg/L in water and 0.025 mg/kg in fish and was specific for I and II in the presence of methylnitrophos, phosphamide, and anthio. A max. permissible concn. of II at 0.003 mg/L water is recommended.

Control of mesta flea beetle Nisotra orbiculata by insecticides under field condition. Pandit, Narayan Chandra; Chakravorty, Sanjib (Jute Agric. Res. Inst., Indian Counc. Agric. Res., Barrackpore 743101, India). Environ. Ecol., 3(1), 95-8 (English) 1985. CODEN: ENECEV. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) The chem. control of mesta flea beetle, (N. orbiculata) under field condition was ineffective with 2 sprayings. The order of effectiveness of insecticides, in the field was carbofuran [1563-66-2] > endosulfan [115-29-7] > chlorfenvinphos [470-90-6] > carbaryl [63-25-2] > phosalone [2310-17-0] > metacide [298-00-0].
