AU 531541 B2 25 Aug 1983, 26 pp. (English). (Australia). CODEN: ALXXAP. CLASS: IC: A01N053-00; A01N057-14; A01N057-16. APPLICATION: AU 80-57855 11 May 1979. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Compns. contg. pyrethroids I (X = F, Cl, Br, WF2C; W = H, F, Cl; Y = H, F, Cl; Z = H or CN) and organophosphates are synergistic acaricides for tick control. Thus, a compn. contg. a-cyano-3-phenoxybenzyl 3-(2-chloro-3,3,3-trifluoroprop-1-en-1-yl)-2,2-dimethylcyclopropane carboxylate [68085-85-8] and ethion [563-12-2] at 50 and 100 ppm, resp., was synergistically active against an organophosphate-resistant strain of Boophilus microplus engorged adults. .

Determination of synthetic pyrethroid residues in wheat grain and flour, rice and tea

Determination of synthetic pyrethroid residues in wheat grain and flour, rice and tea. Kocourek, Vladimir; Havlikova, Ludmila (Vyzk. Ustav Potravinar. Prum., Prague 150 38, Czech.). Sb. UVTIZ, Potravin. Vedy, 4(3), 205-12 (Czech) 1986. CODEN: SUPVE6. DOCUMENT TYPE: Journal CA Section: 17 (Food and Feed Chemistry) Section cross-reference(s): 5 A multiresidual analytic method based on EtOAc extn.In this article, certain chemicals are used. Some of their cas registry numbers are 52645-53-1 and 52315-07-8 , shaking in hexane and MeCN, and purifn. on Florisil deactivated with 3% H2O was developed for the detn. of the residues of cyhalothrin [68085-85-8], permethrin [52645-53-1], cypermethrin [52315-07-8], and deltamethrin [52918-63-5] in wheat grain and flour, rice, and tea. The exts. were purified on Al2O3; conditions suitable for all pyrethroids were not found. The detn. was made by gas chromatog. on a non-polar stationary phase with the use of an electron-capture detector. Reproducibility ranged 87-105%, and the coeffs. of variation were ￡5%. The limit of detection was 0.01 mg/kg. .
