Ethers of 4-halomethylpyridines

Abstract

Compounds are prepared which correspond to the formula ##STR1## wherein Y represents trichloromethyl, dichloromethyl or dichlorofluoromethyl; X represents chloro, bromo, fluoro, alkoxy of 1 to 4 carbon atoms or OR; each R independently represents --(CH.sub.2).sub.3 OR.sup.2, ##STR2## 2-furanylmethyl, 5-alkyl-2-furanylmethyl, tetrahydro-3-furyl, tetrahydro-2-furylmethyl, tetrahydro-2-pyranylmethyl, 2-thiophenemethyl, 2,3-dihydrobenzodioxin-2-ylmethyl or 2,2-dimethyl-1,3-dioxolan-4-ylmethyl; each R' independently represents hydrogen or methyl; R.sup.2 represents hydrogen, alkyl of 1 to 4 carbon atoms or phenyl; R.sup.3 represents hydrogen or alkyl of 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 roots of plants.
