Triadimefon (Bayleton, Amiral, Bay MEB6447) — A chlorophenoxy-dimethyl-trizol-butanone systemic fungicide. If you can pronounce that, you might want to know it works against rust and powdery mildew for about 28 days, but its overuse can cause short bloom stems.
Benomyl (Benlate, Tersan 1991) — A methyl-bensimidazole carbamate systemic fungicide effective for rust and powdery mildew. If you like carbamates like Sevin as an insecticide, you might like this material as a fungicide. What you should also know is these products may affect your kidneys after prolonged and repeated exposures. Some are known teratogenics and mutagenics. (Note: Some forms of benomyl are not labeled for roses in the U.S.)
Triforine (Funginex, Saprol) — A trichloroethylene formamide systemic fungicide long considered the rosarian's favorite. Unfortunately, despite its low oral lethal toxicity, more detailed studies have shown it will metabolize into chloralformamide, four per cent of which remains in your body. This latter chemical is potentially life-threatening in that it has psychogenic and cardiovascular effects after prolonged use. If you like this stuff, stock up now. It won't be around much longer.
