Description

For the first time in 14 years of testing fungicides for efficacy on com, we examined the potential for control of naturally occurring leaf diseases in commercial com fields. In 1994 gray leaf spot had developed extensively over Iowa and there was a high potential for inoculum of the fungus for 1995. The pathogen overwinters on com residue and the disease potential was especially high where com was planted into com stubble.
