4-Halomethylpyridine derivatives having the general formula: <CHEM> wherein Y represents a trichloromethyl, dichloromethyl, or dichlorofluoromethyl group; X represents a chlorine, bromine or fluorine atom, an alkoxy group containing 1 to 4 carbon atoms, or the group OR; wherein each R independently represents an <CHEM> 2-furanylmethyl, 5-(C1-C4 alkyl)- 2-furanylmethyl, tetrahydro-3-furyl, tetrahydro-2-furylmethyl, tetrahydro-2- pyranylmethyl, 2-thiophenylmethyl, 2,3-dihydrobenzodioxin- 2-ylmethyl, or 2,2-dimethyl-1, 3-dioxolan-4-ylmethyl group; each R' independently represents a hydrogen atom or a methyl group; R<2> represents a hydrogen atom, an alkyl group containing 1 to 4 carbon atoms, or a phenyl group; R<3> represents a hydrogen atom or an alkyl group containing 1 to 4 carbon atoms; and each n independently represents an integer of from 1 to 12. These compounds and compositions containing them have been found to be useful as agronomic fungicides, especially useful and valuable for the control of soil-borne plant disease organisms which attack the root of plants. |
