METHOD FOR CONTROLLING FUNGI,BACTERIA AND VIRUSES ON A NONHUMAN LOCUS USING CERTAN 2,3-DIHYDRO-1,4DITHIN1,1,4,4-TETRA USEFUL IN SUCH METHOD AND NOVEL 2,3-DIHYDRO1,4-DITHIIN1,1,4,4,-TETRAOXIDES

摘要

Fungi, bacteria and viruses are controlled, especially on plants, by application of chemicals of the formula: ##STR1## such as 2,3- dihydro-5- phenyl-1,4-dithiin 1,1,4,4-tetroxide, 2-ethyl-5,6-dihydro-3- methyl-1,4- dithiin 1,1,4,4-tetroxide and 2,3-dihydro-5-methyl-2-phenyl-1, 4-dithiin 1, 1,4,4-tetroxide.
