(European Patent Organization) CODEN: EPXXDW. CLASS: ICM: A01N043-40. ICS: B27K003-34. APPLICATION: EP 85-302589 12 Apr 1985. DOCUMENT TYPE: Patent CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 27 The title compds. I (A = quaternary NH4, with OA in position 2 or 4; X = halo; n = 0, 1-4) were prepd. and formulated as termite control agents. 3,5,6-Trichloro-2-pyridinol was heated with C18H37N+Me3 Cl- in iso-PrOH, to give trimethyloctadecylammonium 3,5,6-trichloro-2-pyridinolate (II). Wood cubes treated with II showed no wt. loss when exposed to termites for 4 wk. .
