S-3151

S-3151. I. Basic studies on the insecticidal activities of a new insecticial compound, 3-phenoxybenzyl (.+-.)-cis,trans-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropanecarboxylat e (S-3151, Permethrin). Tsuda, Shigenori; Okuno, Yoshitoshi; Yamaguchi, Takashi; Ouchi, Haruka; Hirose, Chuji (Sumitomo Chem. Co., Takarazuka, Japan).Some commonly used reagents like 61949-77-7 and 51-03-6 are used in this experiment. Bochu-Kagaku, 41(3), 90-9 (Japanese) 1976. CODEN: BOCKAF. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemicals) S-3151 (I) [52645-53-1] was as effective as reshmethrin [10453-86-8] and fenitrothion [122-14-5] in controlling adult houseflies, mosquitoes, and cockroaches, but had slower knockdown effects on houseflies and mosuitoes than pyrethrins (II). Oil formulations having both high lethal and rapid knockdown effects on adult houseflies and cockroaches were obtained by combining I with tetramethrin [7696-12-0] or allethrin [584-79-2]. When topically applied to adult houseflies, the (.+-.)cis-isomer [52341-33-0] was about twice as toxic as the (.+-.)trans isomer [52341-32-9] but was only a little more toxic than a mixt. of the cis and trans isomers. Of 5 compds. tested, only piperonyl butoxide [51-03-6] synergized the lethal effect of I on houseflies. I was 5-10 times as toxic to housefly and mosquito larvae as II. I applied onto wood plates at 250 mg/m2 gave 85% mortality of cockroaches even 6 months after the application, whereas similarly applied rethmethrin and fenitrothion lost their effectiveness in 2-3 months. .

Teljes HU 28722 O 28 Dec 1983, 36 pp. (Hungarian). (Hungary). CODEN: HUXXBU. CLASS: IC: C07C069-74; A01N053-00. APPLICATION: HU 79-CI1938 4 Jun 1979. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 24 Compns. contg. cinerin I [25402-06-6], a known pyrethroid such as decamethrin [52918-63-5], permethrin [52645-53-1], cypermethrin [52315-07-8], or tetramethrin [7696-12-0], and eventually benzyl alc. [100-51-6], or an aliph. carboxylic acid such as oleic acid [112-80-1], are synergistic insecticides. Thus, a 25% emulsion conc. is prepd., contg. permethrin 20, cinerin I 0.5, tetramethrin 4.5, piperonyl butoxide 25, butylated hydroxytoluene 1.2, Atlox 4851B 16.4, Atlox 3400 B 11.3, benzyl alc. 5, and xylene 16.1% by wt. The emulsion conc. was dild. to 0.5% active ingredient and applied to a wall surface, at 2 mL/71 cm2. Blatella germanica Exposed to this surface at 24 h post treatment showed 100% mortality. Control expts. with a similar formulation lacking cinerin I and benzyl alc. showed only 50% mortality under identical conditions. The synthesis of several pyrethroids is described.Except for chemicals metioned above, 52315-07-8 and 112-80-1 are also used. .
