Headline's not recommended round here for rust. Its just a preventative (labeled at 6-12 oz). If you sprayed it early, then it did you no good by the time rust came in. (This of course is the situation here) Rust showed up around Sept. 15th or so in my county. Most of the beans here were at late R5 early R6, with the exception of some late wheat beans. Because of it showing up late, it was more than likely already here but just not found, so we recommended a triazole (prev. and curative).
