Full Definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are included for: (1) (hetero)aryl-pyrazole compounds (X) of formulae (XA) and (XB) and their salts; (2) (hetero)aryl-pyrazole compounds (XI) of formulae (XIA) and (XIB) and their salts, where (XI) exclude 1-({4-[1-(2,2-difluoroethyl)-3-(trimethylstannyl)-1H-pyrazol-4-yl]pyrimidin-2-yl}amino)propan-2-ol; and (3) (hetero)arylamine-pyrazole compounds (III) of formulae (IIIA) and (IIIB) and their salts, where (III) exclude 4-[3-(4-fluorophenyl)-5-methyl-1H-pyrazol-4-yl]pyridin-2-amine, 4-[3-(4-chlorophenyl)-5-methyl-1H-pyrazol-4-yl]pyridin-2-amine, 4-[3-(4-methoxyphenyl)-5-methyl-1H-pyrazol-4-yl]pyridin-2-amine, 4-[3-(4-fluorophenyl)-1H-pyrazol-4-yl]pyrimidin-2-amine, 4-(5-methyl-3-phenyl-1H-pyrazol-4-yl)pyrimidin-2-amine and [4-(2-aminopyrimidin-4-yl)-3-(3-chloro-5-hydroxyphenyl)-1H-pyrazol-1-yl]acetonitrile. PG : tetrahydro-2H-pyran-2-yl; M3 : tributylstannyl, 4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl; and PG1 : tetrahydro-2H-pyran-2-yl or 2-(trimethylsilyl)ethoxymethyl. [Image] [Image] [Image] ACTIVITY : Fungicide; Antibacterial. MECHANISM OF ACTION : None given. The fungicidal activity of (A) against Botrytis cinereawas tested in cucumber plants. The results showed that 4-[3-(4-fluorophenyl)-1-(2-methylpropyl)-1H-pyrazol-4-yl]pyridine (500 ppm) exhibited an activity of 70%.
