D created favorable conditions for the development of downy mildew and purple blotch. Herbicides of the si/m-triazine group that have a strong effect on com also stimulate the dangerous illness common smut (Ustilago maydis) [31]. 

CASRN 5234-68-4 molecular formula C12H13NO2S FW 235.31 Biological. The sulfoxidation of carboxin to carboxin sulfoxide by the fungus Ustilago maydis was reported by Bollag and Liu (1990).

Two fluorescent siderophore analogs, one based on ferrichrome 173 and the second on ferrioxamine 188, were used to study iron transport in the fungus Ustilago maydis that has an uptake system for ferrichrome but lacks a defined ferrioxamine receptor. Nevertheless, ferrioxamine can be utilized by the fungus albeit at a slower rate. 

Combining fluorescence spectroscopy with fluorescence microscopy, confocal microscopy could be used to elucidate the pathway of siderophore-mediat iron uptake in the fungus Ustilago maydis, and visualize this pathway by providing unique fluorescent microscopic images. Using these techniques, clear images of two independent iron-uptake mechanisms have become visualized as well as their cellular compartment locahzed.

Triarimol almost completely suppressed the biosynthesis of ergosterol by Ustilago maydis,162 although total sterol production was unaltered, and (88), obtusifoliol (93), and 14a-methylergosta-8,24(28)-dien-3j8-ol accumulated. These three sterols may be the first intermediates in ergosterol biosynthesis in this organism, although alternative interpretations of the inhibition effects are possible.
