NOVELTY - Sulfur substituted triazole compounds (Q) and their salts are new.    USE - (Q) is useful for: controlling harmful fungi, treating cancer or viral infections, preparing an antimycotic medicaments, and combating zoopathogenic or human pathogenic fungi (all claimed) on cultivated plants e.g. wheat, rye, barley, oats and rice. (Q) are useful to protect technical and non-living materials such as adhesives, glues, wood, paper and paperboard, textiles, leather, paint dispersions, plastics, fiber or fabrics, against the infestation and destruction by harmful microorganisms, such as fungi and bacteria. (Q) are useful to treat retroviral infections such as HIV, human T-lymphotropic viral, influenza viral infection, rhino viral infections and herpes. The ability of (Q) to control soy bean rust caused by Phakopsora pachyrhizi was tested on soy beans. The results showed that the plants treated with 300 ppm of 2-(2-(2-chloro-4-(4-chloro-phenoxy)-phenyl)-4-methyl-(1,3)dioxan-2-yl-methyl)-2H-(1,2,4)triazole-3-thiol exhibited an infection of at most 15%, where the untreated plants were 60% infected.    ADVANTAGE - (Q) exhibits high crop plant compatibility. (Q) are nontoxic, environmentally safer and less costly. (Q) have high effectiveness against broad spectrum of fungi. (Q) provide crops with high yield (e.g. increased biomass and/or increased content of valuable ingredients), improved plant growth, greening effect, quality and tolerance to abiotic and/or biotic stress. (Q) in combination with other active agents e.g. azoxystrobin, benalaxyl, azaconazole, fluazinam and mancozeb exhibit high synergistic effect to combat fungus.    DETAILED DESCRIPTION - Sulfur substituted triazole compounds (Q) of formulae (I) and (II) and their salts are new.    A = 1-5C-alkylene bridge (optionally substituted);    Y1 = e.g. O or S;    R1-R4 = e.g. phenyl, phenyl-1-4C-alkyl, phenyl-1-4C-alkoxy or phenoxy;    R5 = e.g. phenyl, halo, OH, SH or NO2;    R6 = e.g. phenyl, phenyl-1-4C-alkyl or H;    R6a = e.g. phenyl, phenyl-1-4C-alkyl, H or 1-10C-(halo)alkyl;    m = 0-2; and    n = 0-5.    With provisos. Full Definitions are given in the DEFINITIONS (Full Definitions) Field. An INDEPENDENT CLAIM is included for a triazole compound of formula (IV).
