Members conducted research trials in 2014 across multiple environments. Research indicated that fungicide seed treatment products varied in efficacy and some products may reduce final colonization rates of M. phaseolina compared to the non-treated control.

Fungicides applied in-furrow may reduce populations in some environments, but not others, and the result of in-furrow applications on final yield was inconsistent.

Research indicates foliar fungicides applied at any timing between V4 and R5 did not significantly impact plant stand, fungal colonization, or improve yield compared to the non-fungicide treated control.

Results indicate foliar fungicides applied to reduce plant stress and manage charcoal rot would not provide a consistent economic benefit.
